Solid wood panelling and cladding - Characteristics, requirements and marking
This European Standard defines and specifies the relevant characteristics and the appropriate test methods to determine these characteristics for solid wood products to be used as panelling and cladding (including siding) for: • wall and ceiling panelling for internal use, • wall and ceiling cladding for external uses. It provides for the evaluation of conformity and the requirements for marking these products. This European Standard does not cover panels intended for use as stiffening elements. This European Standard does not cover suspended ceiling in wood panelling and cladding. This European Standard does not cover the processes for treatment, surface coating or modification. NOTE Prescriptions for surface coating and treatment can be found in documents valid in the place of use. This European standard does not cover products which are produced from laminated layer section. This European Standard covers treated, untreated and surface coated products, including those made of thermally or chemically modified wood, as well as finger jointed and edge glued products. This European Standard covers products in compliance with EN 14519, EN 15146 and EN 14951,and other solid timber products manufactured for use as panelling and cladding

European foreword
This document (EN 14915:2013/FprA1:2016) has been prepared by Technical Committee CEN/TC 175
“Round and sawn timber”, the secretariat of which is held by AFNOR.
This document is currently submitted to the Unique Acceptance Procedure.
This amendment modifies EN 14915:2013 identifying those clauses of the standard which are needed
for the compliance of the European Standard with the Construction Products Regulation (CPR).
This amendment introduces:
a) a new title;
b) an alternative conditioning in 5.1 "reaction to fire";
c) a new Clause 6 "Assessment and verification of constancy of performance – AVCP" replacing the
existing clause "Evaluation of conformity";
d) a new Annex ZA;
e) editorial changes.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For the relationship with EU Directive(s) see informative Annex ZA, which is an integral part of this
document.
1 Modifications to the title of the European Standard

6 Assessment and verification of constancy of performance - AVCP
6.1 General
The compliance of solid wood panelling product and cladding product with the requirements of this
standard and with the performance 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.
6.2 Type testing
6.2.1 General
All performance related to characteristics included in this standard shall be determined when the
manufacturer intends to declare the respective performance 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-type, such that the results are applicable to the product in question.
NOTE 1 Same AVCP system means testing by an independent third party laboratory where relevant, under the
responsibility of a notified product certification body where relevant.
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 2 Products may be grouped in different families for different characteristics.
Reference to the assessment method standards should be made to allow the selection of a suitable
representative sample.
In addition, the determination of the product-type shall be performed for all essential characteristics
included in the standard for which the manufacturer declares the performance:
at the beginning of the production of a new or modified solid wood panelling product and cladding
product (unless it is a member of a 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 essential characteristic(s), whenever a change occurs in
the solid wood panelling product and cladding product 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 performance.
Where components are used whose performance have already been determined, by the component
manufacturer, on the basis of assessment methods of other product standards, these performance 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 performance declared in the DoP, although this does not
replace the responsibility on solid wood panelling product and cladding product manufacturer to
ensure that the solid wood panelling product and cladding product as a whole is correctly
manufactured and its component products have the declared performance values.
6.2.2 Test samples, testing and compliance criteria
The number of samples of solid wood panelling product and cladding product to be tested/assessed
shall be in accordance with Table 5.
