Foreword
This document (EN 13986:2004/FprA1:2014) has been prepared by Technical Committee CEN/TC 112
“Wood-based panels”, the secretariat of which is held by DIN.
This document is currently submitted to the Unique Acceptance Procedure.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports basic work requirements of Regulation (EU) No
305/2011(CPR) and the essential requirements of EU Directive(s).
For relationship with EU Regulation and Directive(s), see informative Annex ZA which is an integral part of this
document.
This document amends EN 13986:2004.
Compared with EN 13986:2004 the following modifications have been made to take into account amendment
of mandate M113 (M444) made after the publication of the current 2004 version of the standard:
a) introduction of “Racking resistance”, “Embedment strength” and “Air permeability” in Tables 1 to 7, as
relevant;
b) introduction of a new sub-clause 4.8 to deal with dangerous substances other than those already covered
in the standard;
c) additional provisions for classification of reaction to fire included in Clause 5, Table 8;
d) Clause 6 and Annex ZA adapted to CEN/BT documents TF N 548 Rev1 and TF N 530 Rev. 2,
respectively, to meet the terminology and requirements of the Construction Products Regulation;
Note: Due to fact that the Framework Partnership Agreement between the Commission and CEN & CENELEC
is not signed yet, there are currently no New Approach Consultants in place for 2014. Therefore the provisions
of CEN-CENELEC Guide 15 cannot be met.
This shall not prevent the processing of draft standards nor the offering of harmonized standards to the
Commission. In particular, draft standards can be sent to vote without Consultant assessment.
This note will be removed from the Foreword of the finalized publication.

smoke production and flaming droplets/particles, if any) shall be determined, classified and declared:
1)
a) either without the need for further testing (CWFT), as given in Table 8 , if the panel meets the material
characteristics and the end use conditions given therein,
b) or based on testing of the panel according to the relevant test methods, given in standards referred to in
EN 13501-1, when the panel does not meet the requirements of Table 8 or where a higher classification
than the one in a) is sought.
When the option b) is applied and where required by the test method, the panels shall be mounted and fixed
in a manner representative of its intended end use.

Rd,max,k mean
based panels used as wall sheathing on studs shall be determined according to EN 594. The value can only
be used for the tested system.
Alternatively, those parameters which enable the racking strength to be calculated from EN 1995-1-1 can be
declared. For this calculation the panel thickness t and the characteristic lateral load carrying capacity F of
v,k
the actual combination of panel and fastener shall be declared.
NOTE Knowing the characteristic embedment strength f a lower bound for F can be calculated from EN 1995-1-1."
h v,k
Add the following new sub-clauses:
"
5.19 Embedment strength
Where required, the embedment strength f shall be determined according to EN 383 and declared as its
h
characteristic value in Newtons per square millimeter (N/mm ). In addition, the type and diameter of the
fasteners used for the test shall be declared.
The declared characteristic value for the embedment strength is valid only for the type and diameter of the
fastener used for the tests.
Alternatively,those parameters which enable the characteristic embedment strength to be calculated from e.g.
EN 1995-1-1 should be declared.
NOTE The use of other design codes is sometimes required by national provisions.
For plywood the characteristic density ρ should be declared, for hardboard, particleboard and OSB the panel
k
thickness t should be declared.
5.20 Air permeability
The air permeability of wood-based panels is relevant only for external use and shall be determined and
expressed, where required, as the air permeability coefficient according to EN 12114."
4 Modifications to Clause 6 "Evaluation of conformity"
Replace the existing Clause 6 with the following:
"
6 Assessment and verification of constancy of performance - AVCP
6.1 General
The compliance of wood-based panels with the requirements of this standard and with the performances
declared by the manufacturer in the DoP shall be demonstrated by:
 determination of the product type on the basis of type testing;
 factory production control by the manufacturer, including product assessment.
The manufacturer shall always retain the overall control and shall have the necessary means to take
responsibility for the conformity of the product with its declared performance(s).
6.2 Type testing
6.2.1 General
All performances related to characteristics included in this standard shall be determined when the
manufacturer intends to declare the respective performances unless the standard gives provisions for
declaring them without performing tests (e.g. use of previously existing data, CWFT and conventionally
accepted performance).
Assessment previously performed in accordance with the provisions of this standard, may be taken into
account provided that they were made to the same or a more rigorous test method, under the same AVCP
system on the same product or products of similar design, construction and functionality, such that the results
are applicable to the product in question.
For the purposes of assessment, the manufacturer's products may be grouped into families, where it is
considered that the results for one or more characteristics from any one product within the family are
representative for that same characteristics for all products within that same family.
NOTE 1 Products may be grouped in different families for different characteristics.
NOTE 2 Reference to the assessment method standards will be made to allow the selection of a suitable
representative sample.
In addition, the determination of the product type shall be performed for all characteristics included in the
standard for which the manufacturer declares the performance:
 at the beginning of the production of a new or modified wood-based panel (unless a member of the same
product range), or
 at the beginning of a new or modified method of production (where this may affect the stated properties);
or
they shall be repeated for the appropriate characteristic(s), whenever a change occurs in the wood-based
panel design, in the raw material or in the supplier of the components, or in the method of production (subject
to the definition of a family), which would affect significantly one or more of the characteristics.
Where components are used whose characteristics have already been determined, by the component
manufacturer, on the basis of assessment methods of other product standards, these characteristics need not
be re-assessed. The specifications of these components shall be documented.
Products bearing regulatory marking in accordance with appropriate harmonized European specifications may
be presumed to have the performances declared in the DoP, although this does not replace the responsibility
on the wood-based panel manufacturer to ensure that the wood-based panel as a whole is correctly
manufactured and its component products have the declared performance values.
6.2.2 Test samples, testing and compliance criteria
Where sampling of wood-based panels for type testing is required the general principles and definitions of EN
326-1 and EN 326-2 apply. The number of samples shall be in accordance with Table 11.

The minimum number of panels may be reduced to 6, if the product properties can be documented from internal records of at least

6.2.3 Test reports
The results of the determination of the product type shall be documented in test reports. All test reports shall
be retained by the manufacturer for at least 10 years after the last date of production of the wood-based panel
to which they relate.
6.2.4 Shared other party results
A manufacturer may use the results of the product type determination obtained by someone else (e.g. by
another manufacturer, as a common service to manufacturers, or by a product developer), to justify his own
declaration of performance regarding a product that is manufactured according to the same design (e.g.
dimensions) and with raw materials, constituents and manufacturing methods of the same kind, provided that:
– the results are known to be valid for products with the same essential characteristics relevant for the
product performance;
– in addition to any information essential for confirming that the product has such same performances related
to specific essential characteristics, the other party who has carried out the determination of the product
2)
type concerned or has had it carried out, has expressly accepted to transmit to the manufacturer the
results and the test report to be used for the latter’s product type determination, as well as information
regarding production facilities and the production control process that can be taken into account for FPC;
– the manufacturer using other party results accepts to remain responsible for the product having the
declared performances and he also:
– ensures that the product has the same characteristics relevant for performance as the one that has
been subjected to the determination of the product type, and that there are no significant differences
with regard to production facilities and the production control process compared to that used for the
product that was subjected to the determination of the product type; and
– keeps available a copy of the determination of the product type report that also contains the
information needed for verifying that the product is manufactured according to the same design and
with raw materials, constituents and manufacturing methods of the same kind.

2) The formulation of such an agreement can be done by licence, contract, or any other type of written consent.
6.2.5 Cascading determination of the product type results
For some construction products, there are companies (often called “system houses”) which supply or ensure
3)
the supply of, on the basis of an agreement some or all of the components (e.g. in case of windows:
4)
profiles, gaskets, weather strips) to an assembler who then manufactures the finished product (referred to
below as the “assembler”) in his factory.
Provided that the activities for which such a system house is legally established include
manufacturing/assembling of products as the assembled one, the system house may take the responsibility
for the determination of the product type regarding one or several essential characteristics of an end product
which is subsequently manufactured and/or assembled by other firms in their own factory.
When doing so, the system house shall submit an “assembled product” using components manufactured by it
or by others, to the determination of the product type and then make the determination of the product type
report available to the assemblers, i.e. the actual manufacturer of the product placed on the market.
To take into account such a situation, the concept of cascading determination of the product type might be
taken into consideration in the technical specification, provided that this concerns characteristics for which
either a notified product certification body or a notified test laboratory intervene, as presented below.
The determination of the product type report that the system house has obtained with regard to tests carried
out by a notified body, and which is supplied to the assemblers, may be used for the regulatory marking
purposes without the assembler having to involve again a notified body to undertake the determination of the
product type of the essential characteristic(s) that were already tested, provided that:
– the assembler manufactures a product which uses the same combination of components (components with
the same characteristics), and in the same way, as that for which the system house has obtained the
determination of the product type report. If this report is based on a combination of components not
representing the final product as to be placed on the market, and/or is not assembled in accordance with
the system house’s instruction for assembling the components, the assembler needs to submit his finished
product to the determination of the product type;
– the system house has notified to the manufacturer the instructions for manufacturing/assembling the
product and installation guidance;
– the assembler (manufacturer) assumes the responsibility for the correct assembly of the product in
accordance with the instructions for manufacturing/assembling the product and installation guidance
notified to him by the system house;
– the instructions for manufacturing/assembling the product and installation guidance notified to the
assembler (manufacturer) by the system house are an integral part of the assembler’s Factory Production
Control system and are referred to in the determination of the product type report;
– the assembler is able to provide documented evidence that the combination of components he is using,
and his way of manufacturing, correspond to the one for which the system house has obtained the
determination of the product type report (he needs to keep a copy of the system house’s determination of
the product type report);
– regardless the possibility of referring, on the basis of the agreement signed with the system house, to the
latter’s responsibility and liability under private law, the assembler remains responsible for the product
being in compliance with the declared performances, including both the design and the manufacture of the
product, which is given when he affixes the regulatory marking on his product.

3) This can be, for instance, a contract, license or whatever kind of written agreement, which should also contain clear
provisions with regard to responsibility and liability of the component producer (system house, on the one hand, and the
assembler of the finished product, on the other hand.
4) These companies may produce components but they are not required to do so.
6.3 Factory production control (FPC)
6.3.1 General
The manufacturer shall establish, document and maintain an FPC system to ensure that the products placed
on the market comply with the declared performance of the essential characteristics.
The FPC system shall consist of procedures, regular inspections and tests and/or assessments and the use of
the results to control raw and other incoming materials or components, equipment, the production process and
the product.
All the elements, requirements and provisions adopted by the manufacturer shall be documented in a
systematic manner in the form of written policies and procedures.
This factory production control system documentation shall ensure a common understanding of the evaluation
of the constancy of performance and enable the achievement of the required product performances and the
effective operation of the production control system to be checked. Factory production control therefore brings
together operational techniques and all measures allowing maintenance and control of the compliance of the
product with the declared performances of the essential characteristics.
In case the manufacturer has used shared or cascading product type results, the FPC shall also include the
appropriate documentation as foreseen in 6.2.4 and 6.2.5.
6.3.2 Requirements
6.3.2.1 General
The manufacturer is responsible for organizing the effective implementation of the FPC system in line with the
content of this product standard. Tasks and responsibilities in the production control organization shall be
documented and this documentation shall be kept up-to-date.
The responsibility, authority and the relationship between personnel that manages, performs or verifies work
affecting product constancy, shall be defined. This applies in particular to personnel that need to initiate
actions preventing product non-constancies from occurring, actions in case of non-constancies and to identify
and register product constancy problems.
Personnel performing work affecting the constancy of performance of the product shall be competent on the
basis of appropriate education, training, skills and experience for which records shall be maintained.
In each factory the manufacturer may delegate the action to a person having the necessary authority to:
− identify procedures to demonstrate constancy of performance of the product at appropriate stages;
− identify and record any instance of non-constancy;
− identify procedures to correct instances of non-constancy.
The manufacturer shall draw up and keep up-to-date documents defining the factory production control. The
manufacturer's documentation and procedures should be appropriate to the product and manufacturing
process. The FPC system should achieve an appropriate level of confidence in the constancy of performance
of the product. This involves :
a) the preparation of documented procedures and instructions relating to factory production control
operations, in accordance with the requirements of the technical specification to which reference is made;
b) the effective implementation of these procedures and instructions;
c) the recording of these operations and their results;
d) the use of these results to correct any deviations, repair the effects of such deviations, treat any resulting
instances of non-conformity and, if necessary, revise the FPC to rectify the cause of non-constancy of
performance.
Where subcontracting takes place, the manufacturer shall retain the overall control of the product and ensure
that he receives all the information that is necessary to fulfill his responsibilities according to this European
Standard.
If the manufacturer has part of the product designed, manufactured, assembled, packed, processed and/or
labelled by subcontracting, the FPC of the subcontractor may be taken into account, where appropriate for the
product in question.
The manufacturer who subcontracts all of his activities may in no circumstances pass the above
responsibilities on to a subcontractor.
NOTE Manufacturers having an FPC system, which complies with EN ISO 9001 standard and which addresses the
provisions of the present European Standard are considered as satisfying the FPC requirements of the Regulation (EU)
No 305/2011.
6.3.2.2 Equipment
6.3.2.2.1 Testing
All weighing, measuring and testing equipment shall be calibrated and regularly inspected according to
documented procedures, frequencies and criteria.
6.3.2.2.2 Manufacturing
All equipment used in the manufacturing process shall be regularly inspected and maintained to ensure use,
wear or failure does not cause inconsistency in the manufacturing process. Inspections and maintenance shall
be carried out and recorded in accordance with the manufacturer’s written procedures and the records
retained for the period defined in the manufacturer's FPC procedures.
6.3.2.3 Raw materials and components
The specifications of all incoming raw materials and components shall be documented, as shall the inspection
scheme for ensuring their compliance. In case supplied kit components are used, the constancy of
performance system of the component shall be that given in the appropriate harmonized technical
specification for that component.
6.3.2.4 Controls during manufacturing process
The manufacturer shall plan and carry out production under controlled conditions.
6.3.2.5 Product testing and evaluation
The manufacturer shall establish procedures to ensure that the stated values of the characteristics he
declares, are maintained. The characteristics, and the means of control, are given in Table 11. The
manufacturer shall sample the wood-based panels for the FPC testing according to EN 326-1 and shall control
the required performance characteristics of the panel according to EN 326-2. The performance characteristics
given in Tables 1 to 7, that are relevant to the intended end-use conditions, shall be controlled using
frequencies of testing equal to or greater than the frequencies given in Table 12. Sampling shall be carried out
at random.

NOTE 1 These characteristics are controlled by indirect testing of either the panel’s density according to EN 323 and its thickness
according to EN 325 (or any other parameter shown to correlate with the appropriate characteristic) with a frequency sufficient to ensure
that the panel remains representative of that used for initial type testing.
NOTE 2 All periods of time in this table are production times.
NOTE 3 For biological durability, the conformity of preservative treated panels marked PT are assessed either by direct or by indirect
testing of each batch of treated panels. Guidance is given in EN 351-1 and EN 351-2.
a
If several thickness ranges are produced in one 8 h shift, the factory production control shall be organised so that at least one panel
of each thickness range is tested in one week’s production.
b
Certain types of OSB, particleboard, fibreboard, plywood and solid wood panels release little or no formaldehyde. In these cases, the
test intervals may be increased. However, it remains the responsibility of the manufacturer to ensure compliance with the declared
release of formaldehyde class.
c
If required.
6.3.2.6 Non-complying products
The manufacturer shall have written procedures which specify how non-complying products shall be dealt
with. Any such events shall be recorded as they occur and these records shall be kept for the period defined
in the manufacturer’s written procedures.
Where the product fails to satisfy the acceptance criteria, the provisions for non-complying products shall
apply, the necessary corrective action(s) shall immediately be taken and the products or batches not
complying shall be isolated and properly identified.
Once the fault has been corrected, the test or verification in question shall be repeated.
The results of controls and tests shall be properly recorded. The product description, date of manufacture, test
method adopted, test results and acceptance criteria shall be entered in the records under the signature of the
person responsible for the control/test.
With regard to any control result not meeting the requirements of this European Standard, the corrective
measures taken to rectify the situation (e.g. a further test carried out, modification of manufacturing process,
throwing away or putting right of product) shall be indicated in the records.
6.3.2.7 Corrective action
The manufacturer shall have documented procedures that instigate action to eliminate the cause of non-
conformities in order to prevent recurrence.
6.3.2.8 Handling, storage and packaging
The manufacturer shall have procedures providing methods of product handling and shall provide suitable
storage areas preventing damage or deterioration.
6.3.3 Product specific requirements
The FPC system shall address this European Standard and ensure that the products placed on the market
comply with the declaration of performance.
The FPC system shall include a product specific FPC, which identifies procedures to demonstrate compliance
of the product at appropriate stages, i.e:
a) the controls and tests to be carried out prior to and/or during manufacture according to a frequency laid
down in the FPC test plan;
and/or
b) the verifications and tests to be carried out on finished products according to a frequency laid down in the
FPC test plan.
If the manufacturer uses only finished products, the operations under b) shall lead to an equivalent level of
compliance of the product as if FPC had been carried out during the production.
If the manufacturer carries out parts of the production himself, the operations under b) may be reduced and
partly replaced by operations under a). Generally, the more parts of the production that are carried out by the
manufacturer, the more operations under b) may be replaced by operations under a).
In any case the operation shall lead to an equivalent level of compliance of the product as if FPC had been
carried out during the production.
NOTE Depending on the specific case, it can be necessary to carry out the operations referred to under a) and b),
only the operations under a) or only those under b).
The operations under a) refer to the intermediate states of the product as on manufacturing machines and
their adjustment, and measuring equipment etc. These controls and tests and their frequency shall be chosen
based on product type and composition, the manufacturing process and its complexity, the sensitivity of
product features to variations in manufacturing parameters etc.
The manufacturer shall establish and maintain records that provide evidence that the production has been
sampled and tested. These records shall show clearly whether the production has satisfied the defined
acceptance criteria and shall be available for at least three years.
6.3.4 Initial inspection of factory and of FPC
Initial inspection of factory and of FPC shall be carried out when the production process has been finalized
and in operation. The factory and FPC documentation shall be assessed to verify that the requirements of
6.3.2 and 6.3.3 are fulfilled.
During the inspection it shall be verified:
a) that all resources necessary for the achievement of the product characteristics included in this European
standard are in place and correctly implemented;
and
b) that the FPC-procedures in accordance with the FPC documentation are followed in practice;
and
c) that the product complies with the product type samples, for which compliance of the product
performance to the DoP has been verified.
All locations where final assembly or at least final testing of the relevant product is performed, shall be
assessed to verify that the above conditions a) to c) are in place and implemented. If the FPC system covers
more than one product, production line or production process, and it is verified that the general requirements
are fulfilled when assessing one product, production line or production process, then the assessment of the
general requirements does not need to be repeated when assessing the FPC for another product, production
line or production process.
All assessments and their results shall be documented in the initial inspection report.
