Weigh the pyrotechnic composition not contained in pyrotechnic unit(s). Record the mass.
If applicable, remove the pyrotechnic composition from each pyrotechnic unit, and weigh each portion.
Record the mass of each portion.
When safe dismantling is not possible, alternative procedures may be applied.
5.4 Angle of ascent and height of effects
5.4.1 General
The following test method is applicable to articles which are fired vertically or within an angle of ± 15°
from the vertical. In other cases, the test method shall be determined according to the performances of
the article.
5.4.2 Apparatus
— Universal surveying instrument = USI (for instance theodolite) or comparable instruments (4.14).
— Test area (4.2) for the launching of the article.
— A mounting rack, which can be used to fix hand-held articles, might be needed.
5.4.3 Procedure
When determining effect, rising, or bursting height, firing shall take place only in the vertical direction,
i.e. 90° ± 2° from the ground (test area). Measurements shall only take place with a wind velocity of less
than 5 m/s (4.7).
Suitable apparatus for height measurement is any kind of regular device for measuring two angles at the
same time (4.14), specifically the elevation angle (0° - 90°, 1° steps) and the horizontal angle (0° - 360°,
1° steps). The measurement of heights may be made according to one of the methods described in
Annex C as equivalent systems are allowed.
For articles that project pyrotechnic units beyond 30 m or contain pyrotechnic units that are self-
propelling two measuring positions are required. For all other cases one measuring point is adequate. If
two measuring points are necessary, vertical and horizontal angles shall be recorded. In case of one
measuring point, at least the vertical angle shall be recorded.
In order to achieve a reasonable accuracy the distance between firing point and measurement location,
referred to as base length here, shall be adjusted to the measurement device. The vertical angle should
be within the range of 30° to 60° (optimal 45°). If the monitoring position(s) is / are not in the same
horizontal plane as the article, appropriate corrections shall be made in the calculation of heights.
Generally the measuring distance should be adapted to the article (height of ascent expected).
When using two positions for monitoring the height of ascent and angle of flight, they shall be positioned
at a measured distance and, depending on the method of measurement and calculation of the heights,
either at an angle of 90° to each other in relation to the article (See Method 2 of Annex C) or a sufficient
angle to ensure a good validity of the measurement (See Method 1 of Annex C).
5.5 Measurement of sound pressure level
5.5.1 Apparatus
A sound level meter (4.10) and a measuring tape (4.6) are needed.
5.5.2 Procedure
Set up the microphone of the sound level meter (4.10) in the test area (see 4.2) at the safe firing distance
or at a known distance from the main effect point and at a height of 1 m.
Record the maximum C-weighted peak or maximum A-weighted impulse sound pressure levels as
measured by the sound level meter (4.10).
5.6 Timing measurement
5.6.1 Apparatus
Timing device (4.3).
5.6.2 Procedure
5.6.2.1 Ignition time

complete, unopened packs. Cover the test samples or packs and secure them to the platform around its
edges. Run the machine for 1 h.
At the end of the conditioning period stop the machine and remove the test samples or primary packs.
For samples which have been conditioned in primary packs, carefully open the packs, remove the samples
and empty any loose material on to the sheet of paper. Separate any pyrotechnic composition from the
loose material and weigh this pyrotechnic composition with the balance.
Record the mass of loose pyrotechnic composition.
If applicable, verify and record whether the test samples and primary pack exhibit any visible damage
and the safety features are still in the safe position.
For the articles equipped with visible safety features, the safe position shall be verified after the
mechanical conditioning by visual examination.

— the burning time and, where appropriate, the thermal flow rate during the maximum exposure time
specified by the manufacturer.
5.10.3.2 High temperature
When required the test sample shall be placed in a temperature chamber for 24 h at the maximum use
temperature specified by the manufacturer before the function test according to 5.10.3.1.
The articles shall be removed from extreme temperature storage no more than 2 min before the test. This
time interval may be increased for large and massive articles according to acquired experience of testing
bodies.
5.10.3.3 Low temperature
When required the test sample shall be placed in a temperature chamber for 24 h at the minimum use
temperature specified by the manufacturer before the function test according to 5.10.3.1.
The articles shall be removed from extreme temperature storage no more than 2 min before the test. This
time interval may be increased for large and massive articles according to acquired experience of testing
bodies.
5.10.3.4 Verification of safe position
For the articles equipped with integral safety features, the safe position shall be verified after each of the
following tests: mechanical conditioning (5.7), mechanical impact test (5.8) and electrostatic discharge
test (5.13.1.2).
When the safety features are not visible, verification of the safe position require the tested items to be
initiated by functioning the initiating pyrotechnic train before the safety features. This might require a
specific preparation of the tested items depending on their means of ignition. Record any initiation of the
main charge or the pyrotechnic train after the safety features.
5.11 Measurement of thrust
5.11.1 Apparatus
A strain gauge or a piezoelectric type of load cell (4.20) and a timing device (4.3) are needed.
5.11.2 Procedure
Testing of the rocket motor shall be performed to confirm that the rocket motor is within the
manufacturer’s defined tolerances.
The peak thrust, the thrust impulse and burn time shall be measured and recorded.
5.12 Resistance to ignition by an abrasive surface
5.12.1 Apparatus
Abrasive sheet (see 4.16).
5.12.2 Procedure
Strike the friction head of the test sample in the test area (see 4.2) on the rough surface of the abrasive
sheet. Record whether the friction head ignites.
5.13 Further tests
5.13.1 Sensitiveness of pyrotechnic composition
5.13.1.1 General
This test shall be applied when the user might have contact with bare pyrotechnic composition or if
composition is likely to become exposed during normal conditions of handling or use.
