1 Scope This document defines and specifies for wood and parquet flooring the relevant characteristics and the appropriate test methods to determine these characteristics for internal use as flooring. It also applies to wood veneer floor coverings. This document covers flooring defined in EN 13226, EN 13227, EN 13228, EN 13488, EN 13489, EN 13990, EN 13629, prEN 14761 and EN 14354. It does not specify dimensional limits or tolerances, which are given by these same standards. It provides for the evaluation of conformity and the requirements for marking these products.

Not applicable. 4 Performance characteristics required for wood and parquet flooring 4.1 General For construction precautions see Annex A. For moisture content, the equilibrium of wood and parquet flooring will depend on the surrounding temperature and relative humidity of the site before installation and on the service conditions. Dimensional characteristics of products shall be respected in accordance with those defined in the product standard to which the product belongs. Furthermore the type of laying may limit the use of the product. Consequently, indications of use linked to the type of laying (nailed, glued, floating) has to be indicated and it is linked to the type of use. NOTE The following characteristics, mentioned in the mandate issued to CEN by the European Commission and the European Free Trade Association, under the EU Construction Products Directive (see Annex ZA), listed hereafter are not relevant to wood flooring: emission of radioactivity, release of asbestos, water tightness or tactility/visibility. 4.2 List of performance characteristics required for wood and parquet flooring The following performance characteristics shall, where the manufacturer wishes to claim performance (e.g. where the product is subject to regulatory requirements), be determined: – reaction to fire: see 5.1; – release of formaldehyde: see 5.2; SIST EN 14342:2005

6 Evaluation of conformity 6.1 General The conformity of wood flooring products with the requirements of this standard shall be demonstrated by: - initial type testing or assessment; - factory production control by the manufacturer. 6.2 Initial type testing or assessment The initial type testing/assessment shall be performed to demonstrate conformity with this standard or be demonstrated according to information given in this standard. Tests previously performed in accordance with the provisions of this standard (same product, same characteristic, test method, system of attestation of conformity, etc.) may be taken into account for initial type testing. For the purposes of testing, products may be grouped into families, where it is considered that a given property or properties is/are common for all products within the family. When the product specification is amended, which could significantly change one or more of the characteristics (listed in 4.2 and Clause 5), the type assessment or testing shall be repeated for the appropriate characteristic(s). The verification of the characteristic(s) itself is not necessary when tabulated SIST EN 14342:2005

The producer shall maintain, establish, document and have a production control system to ensure that the products placed on the market conform with the stated performance characteristics. The control system shall consist of procedures, regular inspections and test/or assessment; the results shall be used to control raw and other incoming materials or components, equipment, the production process and the product shall be sufficiently detailed to ensure that the conformity of the product is apparent. If a manufacturer claims compliance with FPC requirements by operating an EN ISO 9001 system,
EN ISO 9001 shall be applied in full and shall be made specific to the requirements of this standard.
The performance characteristics relevant to the intended application shall be controlled according to the provisions of 6.3.4. 6.3.2 Procedures when control criteria are not met Procedures to be followed when control values and criteria are not met shall be established by the producer. 6.3.3 Record of documentation The result of inspections, tests or assessments requiring action shall be recorded. Records shall be kept for at least two years, but shall also fulfil the regulatory system and/or the legal requirements of the country concerned. 6.3.4 FPC testing 6.3.4.1 General For the purposes of factory production control (FPC) according to this standard, indirect testing and documentary control may be used as an alternative to the test methods used for initial type testing, as long as the manufacturer is able to demonstrate a relationship between the indirect method(s) and the characteristic in question. 6.3.4.2 For reaction to fire (expressed in term of classes) The manufacturer shall control regularly the composition of the elements produced, at a sufficient frequency to ensure that, for CWFT products, the requirements of Table 1 are satisfied and, for tested products, to ensure that the product remains in the same class as that obtained in the initial type test. If a fire retardant treated product is used, the indications given by the manufacturer to maintain the characteristics shall be observed. The classification requirements shall be satisfied with a probability Pk of 100 % that the test value is no less than that required, with an allowable probability of acceptance, CR, of the product not conforming of 5 %, i.e. a confidence level of 0,95. 6.3.4.3 For formaldehyde content (expressed in term of classes) Where the manufacturer uses no formaldehyde containing materials, the manufacturer shall continue to check, with a frequency defined in his FPC manual, that no such material is used. For formaldehyde containing materials, the manufacturer shall use the provisions of Table B.1 or B.2 with a frequency sufficient to ensure that the class is obtained, with a probability Pk of 90 % and with an allowable probability of acceptance, CR, of the product not SIST EN 14342:2005

Where a manufacturer claims a breaking strength value, tests shall be made according to EN 1533 with a sampling of 30 elements or strips. For FPC, the manufacturer shall ensure that the species used remain the same, and elements have the same composition and class (visual class) on a continuous basis, so that no faults likely to reduce the breaking strength are present. 6.3.4.6 Slipperiness (expressed in term of values or classes) If a slipperiness value is declared, the manufacturer shall ensure that the wood used in the wear layer, and the surface finish or finishing (e.g. the addition of varnish or polish) remain the same as that submitted for initial type testing. Tests shall be made according to the indications given in 5.5 with a sampling of
30 elements. No FPC testing is necessary as long as the wood used in the wear layer, the surface finish or the surface finishing do not change. If they do change, the manufacturer shall repeat the initial type test.
6.3.4.7 Thermal conductivity (expressed in terms of values) Where a thermal conductivity value is declared, the manufacturer shall ensure that the continuous mean density of the material does not change by more than ± 5 % (wit
