CEN/TS 1317-7 :2023 (E)
Introduction
The design purpose of safety barriers installed on roads is to contain errant vehicles that either leave the
carriageway or are likely to encroach into the path of oncoming vehicles. EN 1317-2:2010 deals with the
impact performance of a safety barrier to which a terminal may be attached.
Terminals, which are defined as the beginning and/or end treatment of a safety barrier, are required to
have specified impact performances without introducing additional hazards for passenger cars.
The description of a terminal conforming to this document incorporates the relevant categories and
restraint categories of the product.
Turned down terminals are particular end-treatments that have, historically, been designed to ‘anchor’
and ‘end’ sections of safety barrier. Turned down terminals consisting of modified components of the
barrier do not generally offer a significant level of energy absorbing capacity but can be tested according
to this technical specification if required.
NOTE Some National Road Authorities have in the past years developed national rules that, when satisfied,
allow the use of such systems within their national jurisdiction without the need of further testing.
In this document reference is made to the use of virtual testing according to EN 16303:2020. Therefore
it may be necessary to arrange further rules for the use of virtual testing.

5 Terminal performance
5.1 General
Axial forces to the barrier should be measured or evidence should be given by static calculation or by
virtual testing using models according to EN 16303:2020, if it is intended to use the terminal with
different barriers, unless the terminal does not transfer any load to the connecting barrier.
5.2 Determination of the Datum Point and Structural Length
The structural length of the terminal (Ls) should be determined by the test house, after the Approach 1
test has been performed if this approach is required (or, after that of Approach 2 if no Approach 1 test is
required) before the other required tests are performed. Some designs of terminal might incorporate a
non-structural beginning (nose) which offers no significant influence (for example resistance) to an
impact. The first point at which the terminal offers significant influence (for example resistance) to an
impact with Approach 1 is defined as the datum point. For restraint categories T50 and T80/1/2/3, this
information can be derived from Approach 2.
The datum point should be chosen by the test house according to the definition given in 3.5 and identified
as described above and justified in the test report. If the datum point cannot be chosen directly from the
CEN/TS 1317-7 :2023 (E)
design of the terminal or the manufacturer does not agree to the chosen datum point the datum point
should be determined by the test house on the basis of the results of the Approach 1 test if this approach
is required (or, on that of Approach 2 if no Approach 1 test is required).For energy absorbing terminals
the datum point is the foremost point of the test item where the test vehicle hast lost 5 % of the nominal
impact speed.
For turned down terminals, the terminal datum point should be defined as the first point 200 mm above
ground level.
NOTE The speed of the test vehicle could be derived from the vehicle instrumentation or from high speed video
and the corresponding vehicle position from high speed video or another suitable method can be used.
If a part of the barrier overlaps with the terminal or is required to deform in a controlled manner as part
of the normal functioning of the terminal, then this length of the barrier should be included in Ls. For
turned down terminals the length of the terminal should be the longitudinal length from the beginning of
the terminal to the first point of the barrier with unchanged design (including full height of the barrier).
The total length of the terminal (Lt) should conform to the design specification. For tests, the terminal
should be installed with the terminal manufacturer’s minimum specified length of safety barrier (Lb) so
as to demonstrate the full performance of the terminal but not shorter than 20 m. For tests that were
carried out in accordance with ENV 1317-4:2001 before this document was published, a shorter length
is acceptable, provided the full performance of the terminal is demonstrated. The same barrier type
should be used within all of the testing for a particular terminal product.
5.3 Restraint and direction categories
5.3.1 General
Terminals should be tested in accordance with Table 1 and Table 3. The restraint categories given in
Table 1 are classified according to an increasing containment capacity.
A successfully tested installation at a given restraint category, should be considered as having met
conditions of lower restraint categories with the same direction category (see Table 2).
The impact test configurations are specified in Table 3.
NOTE 1 Some of the performances of terminals are common to crash cushions. Accordingly, some of the tests
specified for terminals in the present document have the same impact conditions specified in EN 1317-3:2010 for
crash cushions. Nevertheless, some other tests are different. The main differences between terminals and crash
cushions are:
• for terminals:
o a terminal is designed to be installed at the beginning and/or at the end of a barrier whereas a
crash cushion is intended to avoid or attenuate vehicle impacts with different types of obstacle,
o a terminal should be joined to a barrier, with a smooth alignment with no risk of snagging or
pocketing,
o in general a terminal is designed to provide an anchorage to the barrier and to have adequate
reaction to the axial tensile force from the barrier under impact.
The above three points might also apply to crash cushions connected to a barrier.
• for crash cushions:
o a crash cushion can be connected to the obstacle that it protects,
o a crash cushion is always energy absorbing while a terminal can be NEAT.

CEN/TS 1317-7 :2023 (E)
Category T80/3 should only be used for the testing of non-energy absorbing terminals. Category T80/3
offers a lower level of safety than categories T80/2, TB80/1 and TB80.
5.3.2 Impact points
The CIP should be chosen along 5 m section of the connecting safety barrier as presented in the Figure 4.
The initial vehicle impact in all tests should generally be at the points indicated in Figure 4.
The impact points should be identified as shown in Figure 4 unless these do not demonstrate the worst-
case testing conditions of the terminal, in terms of the performance of the terminal to be determined
according to Clause 5 (e.g. restraint category, total permanent displacement zone, impact severity
category) and should include any sensitive feature of the design, following the guidelines set out in
Annex B. If the test house chooses an impact point other than those outlined below, in order to ensure
worst-case conditions, then this choice should be justified in the test report.
The impact points on a terminal should be determined considering only its structural parts.
a) Approach 1: Frontal, 0° centre of terminal head
b) Approach 2: Frontal, offset by ¼ of the vehicle width to the traffic side
c) Approach 3: 15° vehicle centreline on centre of terminal head
CEN/TS 1317-7 :2023 (E)
d) Approach 4: 15° vehicle impact at 2/3 LS on terminal traffic side
e) Approach 5: 165° vehicle impact at ½ LS on terminal traffic side
f) Approach 6: 165° vehicle impact on barrier before connection to terminal, at critical impact
point

Figure 4 — Vehicle approach paths
Approaches 4 and 5 should be run after determination of Ls on the basis of the terminal behaviour from
Approach 1 test or, in the case of categories T80/1 or 2, from the Approach 2 test.
CEN/TS 1317-7 :2023 (E)
Approach 5 will not be run for a terminal which is not parallel to the line of the original traffic face of the
barrier if the angle β of the vehicle path to the traffic face of the terminal is less than 5°, at the relevant
impact point and from this point to the head of the terminal (Figure 5).
Terminals should be classified as either single sided (ST) or double sided (DT) systems. This classification
should be reported within the test report.
In the case of non-symmetrical double sided terminals, tests for Approaches 2, 3, 4, and 5 required for
the corresponding restraint and direction categories should be carried out on both sides of the terminal.
Figure 5 — Terminal configuration not requiring an Approach 5 test (if β<5°)
5.4 Tests for ranges of terminals
A group of terminal products of comparable design covering a range of restraint categories can be derived
from a parent terminal, once the latter has been successfully tested to the present document and
providing that all products in this range (parent and derived terminals):
a) are assembled from the same set of components;
b) have the same root product name;
c) have the same working mechanism for the complete product system and for its constituent
components.
The group, specified by the drawings of all the models, may be tested as a range, i.e. a product with
multiple performance possibilities. If the tests specified by the group test matrix are passed, the terminal
should be accepted as a multiple performance product range, i.e. each member is accepted in the relevant
restraint category.
The parent terminal should be of direction category BDT. The parent terminal should belong to the
highest restraint category of the range.
If the highest restraint category of the range is to be increased, the test matrix of Table 1 should be fully
completed for the parent terminal, taking into account any tests which may have already been completed.
CEN/TS 1317-7 :2023 (E)
The test matrix for child terminals, that is to say terminals in a range of products other than the parent,
should be as shown in Tables 4, 5, 6, 7, 8, 9, 10 and 6d depending on the highest restraint category of the
range.
NOTE A range of terminals could for example be built in the following way:
In this example the parent terminal named “Term(10)” consists of 10 energy-absorbing components and is
classified as T110 BDT.
A child terminal, named “Term(9)” could be constructed for example by reducing the length of “Term(10)” and
reducing the number of energy absorbing-components to 9. Apart from that, “Term(9)” is identical to “Term(10)”.
“Term(9)” could be classified for example as T80 BDT according to Table 4a if “Term(9)” passes the tests TT1.2.80,
TT3.1.80 and TT4.2.80. If no more child terminals are added to the range of terminals this is given by: “Term(10)”
– T110 BDT and “Term(9)” – T80 BDT.
Note that in this example “Term(10)” could also be used un-modified as a T100 BDT – terminal or any lower
restraint category according to Table 2.

If the terminal connection-transition is modified, this modification should be assessed in accordance with
CEN/TR 1317-10.
5.5 Impact severity
The vehicle occupant impact severity assessment indices, ASI and THIV, should be evaluated. ASI and
THIV should conform to the requirements of Table 7 for the tests indicated in Table 1 and 3.
These indices are defined in EN 1317-1.
Two severity categories are determined in Table 11 as a function of the values of ASI and THIV.
Table 11 — Terminals: Vehicle impact severity categories
Impact severity
Index values
categories
A ASI ≤ 1,0 and THIV ≤ 44 km/h in Approach 1, 2 and 3
THIV ≤ 33 km/h in Approach 4, 5 and 6
B ASI ≤ 1,4 and THIV ≤ 44 km/h in Approach 1, 2 and 3
THIV ≤ 33 km/h in Approach 4, 5 and 6
NOTE 1 Impact severity category A affords a greater level of safety for the occupants of an errant vehicle than category B.
NOTE 2 The limit value for THIV is higher in Approach 1, 2 and 3 because experience has shown that higher values can be
tolerated by occupants in frontal impacts (also because of better passive safety in this direction). Such a difference in human
tolerance between frontal and lateral impacts is already considered in the ASI parameter, which therefore does not need to
be changed.
5.6 Static, dynamic and total permanent displacements of terminal
The dynamic and the static lateral displacement of the terminal test installation including the attached
barrier and the static displacement of any detached part of the terminal should be measured. The
measurements should be taken separately for the traffic and the departure sides (Figure 6).
The dynamic displacement is the maximum lateral distance, during the test, between the foremost point
of the undeformed traffic side of the test installation including terminal and barrier and the maximum
dynamic position of any part of the terminal or barrier on the departure side.
The static displacement is measured in the same way as the dynamic displacement but not less than 10
min and no more than two hours after the impact.
The static displacement of the detached parts is measured in the same way as the static displacement of
the terminal but with reference to any detached part of the terminal with a mass greater than or equal to
2,0 kg instead of reference to the deformed terminal.
The total permanent displacement is given by the maximum of the static displacement of the terminal
and the static displacements of detached parts.
The dynamic and the static displacement of the terminal, the static displacement of the detached parts
and the total permanent displacement should be recorded in the test report, separately for the traffic and
the departure side.
For tests that were carried out in accordance with ENV 1317-4:2001 before this document was published,
the total permanent lateral displacement determined according to the ENV 1317-4:2001 is acceptable.
NOTE Terminals can be made with materials that slowly recover towards their original shape following a test.
The minimum time of 10 min after the test is allowed for any self restoring motion. The maximum time of two hours
is prescribed to prevent any change of the final configuration from external factors.
To meet a category S or T, the total permanent displacement of the terminal, under all the tests required
by its restraint categories, should remain within distances S and T from the traffic side of the barrier, as
shown in Table 12. The distances S and T are shown in Figure 6.

5.7 Impact test acceptance criteria
5.7.1 General
In order to consider that a terminal has performed acceptably in a test and to determine product
performance on the basis of all test required by the present document for the specified performance
categories, the following impact acceptance criteria should be met.
CEN/TS 1317-7 :2023 (E)
5.7.2 Terminal behaviour
No element of the terminal test installation (including barrier) should penetrate the passenger
compartment of the vehicle. Any penetration or deformation of the passenger compartment should be
recorded in the test report.
Although any deformation of the passenger compartment should be reported, the present document does
not currently provide a method to assess the resulting risk of injury to vehicle occupants. The level of
deformation considered to be acceptable should be determined at a national level.
All totally detached parts of the terminal with a mass greater than or equal to 2,0 kg should be included
in the determination of the displacement classification (see 5.6).
For approaches 4, 5 and 6 there should be no complete breakage of any of the principal longitudinal
elements of either the terminal or the connected safety barrier system.
Anchorages and fixings should perform to the terminal design specifications and other specified
requirements as listed in the test report.
5.7.3 Test vehicle behaviour
5.7.3.1 General
The vehicle should not roll over (including rollover of the vehicle onto its side) during or after impact.
The post-impact trajectory of the test vehicle should be reported by means of the redirection zone shown
in Figures 7,8 and 9 and in Table 13.

CEN/TS 1317-7 :2023 (E)
Introduction
The design purpose of safety barriers installed on roads is to contain errant vehicles that either leave the
carriageway or are likely to encroach into the path of oncoming vehicles. EN 1317-2:2010 deals with the
impact performance of a safety barrier to which a terminal may be attached.
Terminals, which are defined as the beginning and/or end treatment of a safety barrier, are required to
have specified impact performances without introducing additional hazards for passenger cars.
The description of a terminal conforming to this document incorporates the relevant categories and
restraint categories of the product.
Turned down terminals are particular end-treatments that have, historically, been designed to ‘anchor’
and ‘end’ sections of safety barrier. Turned down terminals consisting of modified components of the
barrier do not generally offer a significant level of energy absorbing capacity but can be tested according
to this technical specification if required.
NOTE Some National Road Authorities have in the past years developed national rules that, when satisfied,
allow the use of such systems within their national jurisdiction without the need of further testing.
In this document reference is made to the use of virtual testing according to EN 16303:2020. Therefore
it may be necessary to arrange further rules for the use of virtual testing.

5.1 General
Axial forces to the barrier should be measured or evidence should be given by static calculation or by
virtual testing using models according to EN 16303:2020, if it is intended to use the terminal with
different barriers, unless the terminal does not transfer any load to the connecting barrier.
5.2 Determination of the Datum Point and Structural Length
The structural length of the terminal (Ls) should be determined by the test house, after the Approach 1
test has been performed if this approach is required (or, after that of Approach 2 if no Approach 1 test is
required) before the other required tests are performed. Some designs of terminal might incorporate a
non-structural beginning (nose) which offers no significant influence (for example resistance) to an
impact. The first point at which the terminal offers significant influence (for example resistance) to an
impact with Approach 1 is defined as the datum point. For restraint categories T50 and T80/1/2/3, this
information can be derived from Approach 2.
The datum point should be chosen by the test house according to the definition given in 3.5 and identified
as described above and justified in the test report. If the datum point cannot be chosen directly from the
CEN/TS 1317-7 :2023 (E)
design of the terminal or the manufacturer does not agree to the chosen datum point the datum point
should be determined by the test house on the basis of the results of the Approach 1 test if this approach
is required (or, on that of Approach 2 if no Approach 1 test is required).For energy absorbing terminals
the datum point is the foremost point of the test item where the test vehicle hast lost 5 % of the nominal
impact speed.
For turned down terminals, the terminal datum point should be defined as the first point 200 mm above
ground level.
NOTE The speed of the test vehicle could be derived from the vehicle instrumentation or from high speed video
and the corresponding vehicle position from high speed video or another suitable method can be used.
If a part of the barrier overlaps with the terminal or is required to deform in a controlled manner as part
of the normal functioning of the terminal, then this length of the barrier should be included in Ls. For
turned down terminals the length of the terminal should be the longitudinal length from the beginning of
the terminal to the first point of the barrier with unchanged design (including full height of the barrier).
The total length of the terminal (Lt) should conform to the design specification. For tests, the terminal
should be installed with the terminal manufacturer’s minimum specified length of safety barrier (Lb) so
as to demonstrate the full performance of the terminal but not shorter than 20 m. For tests that were
carried out in accordance with ENV 1317-4:2001 before this document was published, a shorter length
is acceptable, provided the full performance of the terminal is demonstrated. The same barrier type
should be used within all of the testing for a particular terminal product.
5.3 Restraint and direction categories
5.3.1 General
Terminals should be tested in accordance with Table 1 and Table 3. The restraint categories given in
Table 1 are classified according to an increasing containment capacity.
A successfully tested installation at a given restraint category, should be considered as having met
conditions of lower restraint categories with the same direction category (see Table 2).
The impact test configurations are specified in Table 3.
NOTE 1 Some of the performances of terminals are common to crash cushions. Accordingly, some of the tests
specified for terminals in the present document have the same impact conditions specified in EN 1317-3:2010 for
crash cushions. Nevertheless, some other tests are different. The main differences between terminals and crash
cushions are:
• for terminals:
o a terminal is designed to be installed at the beginning and/or at the end of a barrier whereas a
crash cushion is intended to avoid or attenuate vehicle impacts with different types of obstacle,
o a terminal should be joined to a barrier, with a smooth alignment with no risk of snagging or
pocketing,
o in general a terminal is designed to provide an anchorage to the barrier and to have adequate
reaction to the axial tensile force from the barrier under impact.
The above three points might also apply to crash cushions connected to a barrier.
• for crash cushions:
o a crash cushion can be connected to the obstacle that it protects,
o a crash cushion is always energy absorbing while a terminal can be NEAT.

For this test condition, the ATD required by EN 1317-1 should be located at the more distant location from the
centre line of the terminal. For tests that were carried out in accordance with ENV 1317-4:2001 before the present
document was published, a different location of the ATD is acceptable.
The vehicle width should be the maximum width of the vehicle at its widest point, excluding any side
mirrors.
CEN/TS 1317-7 :2023 (E)
Category T80/3 should only be used for the testing of non-energy absorbing terminals. Category T80/3
offers a lower level of safety than categories T80/2, TB80/1 and TB80.
5.3.2 Impact points
The CIP should be chosen along 5 m section of the connecting safety barrier as presented in the Figure 4.
The initial vehicle impact in all tests should generally be at the points indicated in Figure 4.
The impact points should be identified as shown in Figure 4 unless these do not demonstrate the worst-
case testing conditions of the terminal, in terms of the performance of the terminal to be determined
according to Clause 5 (e.g. restraint category, total permanent displacement zone, impact severity
category) and should include any sensitive feature of the design, following the guidelines set out in
Annex B. If the test house chooses an impact point other than those outlined below, in order to ensure
worst-case conditions, then this choice should be justified in the test report.
The impact points on a terminal should be determined considering only its structural parts.
a) Approach 1: Frontal, 0° centre of terminal head

Approaches 4 and 5 should be run after determination of Ls on the basis of the terminal behaviour from
Approach 1 test or, in the case of categories T80/1 or 2, from the Approach 2 test.
CEN/TS 1317-7 :2023 (E)
Approach 5 will not be run for a terminal which is not parallel to the line of the original traffic face of the
barrier if the angle β of the vehicle path to the traffic face of the terminal is less than 5°, at the relevant
impact point and from this point to the head of the terminal (Figure 5).
Terminals should be classified as either single sided (ST) or double sided (DT) systems. This classification
should be reported within the test report.
In the case of non-symmetrical double sided terminals, tests for Approaches 2, 3, 4, and 5 required for
the corresponding restraint and direction categories should be carried out on both sides of the terminal.
Figure 5 — Terminal configuration not requiring an Approach 5 test (if β<5°)
5.4 Tests for ranges of terminals
A group of terminal products of comparable design covering a range of restraint categories can be derived
from a parent terminal, once the latter has been successfully tested to the present document and
providing that all products in this range (parent and derived terminals):
a) are assembled from the same set of components;
b) have the same root product name;
c) have the same working mechanism for the complete product system and for its constituent
components.
The group, specified by the drawings of all the models, may be tested as a range, i.e. a product with
multiple performance possibilities. If the tests specified by the group test matrix are passed, the terminal
should be accepted as a multiple performance product range, i.e. each member is accepted in the relevant
restraint category.
The parent terminal should be of direction category BDT. The parent terminal should belong to the
highest restraint category of the range.
If the highest restraint category of the range is to be increased, the test matrix of Table 1 should be fully
completed for the parent terminal, taking into account any tests which may have already been completed.
CEN/TS 1317-7 :2023 (E)
The test matrix for child terminals, that is to say terminals in a range of products other than the parent,
should be as shown in Tables 4, 5, 6, 7, 8, 9, 10 and 6d depending on the highest restraint category of the
range.
NOTE A range of terminals could for example be built in the following way:
In this example the parent terminal named “Term(10)” consists of 10 energy-absorbing components and is
classified as T110 BDT.
A child terminal, named “Term(9)” could be constructed for example by reducing the length of “Term(10)” and
reducing the number of energy absorbing-components to 9. Apart from that, “Term(9)” is identical to “Term(10)”.
“Term(9)” could be classified for example as T80 BDT according to Table 4a if “Term(9)” passes the tests TT1.2.80,
TT3.1.80 and TT4.2.80. If no more child terminals are added to the range of terminals this is given by: “Term(10)”
– T110 BDT and “Term(9)” – T80 BDT.
Note that in this example “Term(10)” could also be used un-modified as a T100 BDT – terminal or any lower
restraint category according to Table 2.

If the terminal connection-transition is modified, this modification should be assessed in accordance with
CEN/TR 1317-10.
5.5 Impact severity
The vehicle occupant impact severity assessment indices, ASI and THIV, should be evaluated. ASI and
THIV should conform to the requirements of Table 7 for the tests indicated in Table 1 and 3.
These indices are defined in EN 1317-1.
Two severity categories are determined in Table 11 as a function of the values of ASI and THIV.
Table 11 — Terminals: Vehicle impact severity categories
Impact severity
Index values
categories
A ASI ≤ 1,0 and THIV ≤ 44 km/h in Approach 1, 2 and 3
THIV ≤ 33 km/h in Approach 4, 5 and 6
B ASI ≤ 1,4 and THIV ≤ 44 km/h in Approach 1, 2 and 3
THIV ≤ 33 km/h in Approach 4, 5 and 6
NOTE 1 Impact severity category A affords a greater level of safety for the occupants of an errant vehicle than category B.
NOTE 2 The limit value for THIV is higher in Approach 1, 2 and 3 because experience has shown that higher values can be
tolerated by occupants in frontal impacts (also because of better passive safety in this direction). Such a difference in human
tolerance between frontal and lateral impacts is already considered in the ASI parameter, which therefore does not need to
be changed.
5.6 Static, dynamic and total permanent displacements of terminal
The dynamic and the static lateral displacement of the terminal test installation including the attached
barrier and the static displacement of any detached part of the terminal should be measured. The
measurements should be taken separately for the traffic and the departure sides (Figure 6).
The dynamic displacement is the maximum lateral distance, during the test, between the foremost point
of the undeformed traffic side of the test installation including terminal and barrier and the maximum
dynamic position of any part of the terminal or barrier on the departure side.
The static displacement is measured in the same way as the dynamic displacement but not less than 10
min and no more than two hours after the impact.
The static displacement of the detached parts is measured in the same way as the static displacement of
the terminal but with reference to any detached part of the terminal with a mass greater than or equal to
2,0 kg instead of reference to the deformed terminal.
The total permanent displacement is given by the maximum of the static displacement of the terminal
and the static displacements of detached parts.
The dynamic and the static displacement of the terminal, the static displacement of the detached parts
and the total permanent displacement should be recorded in the test report, separately for the traffic and
the departure side.
For tests that were carried out in accordance with ENV 1317-4:2001 before this document was published,
the total permanent lateral displacement determined according to the ENV 1317-4:2001 is acceptable.
NOTE Terminals can be made with materials that slowly recover towards their original shape following a test.
The minimum time of 10 min after the test is allowed for any self restoring motion. The maximum time of two hours
is prescribed to prevent any change of the final configuration from external factors.
To meet a category S or T, the total permanent displacement of the terminal, under all the tests required
by its restraint categories, should remain within distances S and T from the traffic side of the barrier, as
shown in Table 12. The distances S and T are shown in Figure 6.

5.7 Impact test acceptance criteria
5.7.1 General
In order to consider that a terminal has performed acceptably in a test and to determine product
performance on the basis of all test required by the present document for the specified performance
categories, the following impact acceptance criteria should be met.
CEN/TS 1317-7 :2023 (E)
5.7.2 Terminal behaviour
No element of the terminal test installation (including barrier) should penetrate the passenger
compartment of the vehicle. Any penetration or deformation of the passenger compartment should be
recorded in the test report.
Although any deformation of the passenger compartment should be reported, the present document does
not currently provide a method to assess the resulting risk of injury to vehicle occupants. The level of
deformation considered to be acceptable should be determined at a national level.
All totally detached parts of the terminal with a mass greater than or equal to 2,0 kg should be included
in the determination of the displacement classification (see 5.6).
For approaches 4, 5 and 6 there should be no complete breakage of any of the principal longitudinal
elements of either the terminal or the connected safety barrier system.
Anchorages and fixings should perform to the terminal design specifications and other specified
requirements as listed in the test report.
5.7.3 Test vehicle behaviour
5.7.3.1 General
The vehicle should not roll over (including rollover of the vehicle onto its side) during or after impact.
The post-impact trajectory of the test vehicle should be reported by means of the redirection zone shown
in Figures 7,8 and 9 and in Table
...
