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

EN 14342:2005 (E) 8 5.2 Release of formaldehyde The formaldehyde release of wood flooring products shall be determined according to annex B. The declared values are expressed in term of classes. Solid wood as such, without chemical treatment, without adhesive, without coating or finishing, has no formaldehyde release of significance. 5.3 Content of pentachlorophenol Parquet and wood flooring normally contains less than 5 ppm of pentachlorophenol (PCP). If the product contains raw materials that include PCP (may concern soft wood treated against blue stain), then the product shall be tested according to methods valid in the country of use of the product. In case the value of 5 ppm is exceeded, the indication “PCP > 5 ppm" shall be added to the marking. NOTE CEN/TR 14823 has been developed by CEN/TC 38. 5.4 Breaking strength If breaking strength is required, it shall be tested for the installation required according to EN 1533 depending on the risk, if any. The result shall be expressed in terms of maximum load. This requirement does not apply to veneer floor coverings. 5.5 Slipperiness Where the manufacturer wishes to declare a slipperiness value (e.g. where subject to regulatory requirements), the slipperiness shall be determined in accordance with the pendulum test described in EN 1339:2003, Annex J. 5.6 Thermal conductivity The thermal conductivity shall be determined only for uses subject to thermal insulation requirements. It shall either be determined according to EN 12664 or given by using tabulated values related to density as shown in Table 2, taken from EN 12524. For multi-layer flooring take the summation of the values of thermal resistance for each layer. The thermal resistance R (m2 K/W) of solid wood flooring is given by the formula:
where t is the thickness of the wood flooring in m and λ is the thermal conductivity in W/m K. The thermal resistance R of a multi-layer parquet is given by the formula: where each layer is characterised by its thickness t and its thermal conductivity λ.

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
EN 14342:2005 (E) 10 values of Clause 5 are used. Where wood flooring products are made from raw materials for which one or more of the characteristics in 4.2 and Clause 5 are already known (e.g. by the material being CE marked), the testing or assessment of such characteristics does not need to be repeated for the finished flooring product, as long as the manufacturing process does not change these characteristics. 6.3 Factory production control 6.3.1 General
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
EN 14342:2005 (E) 11 conforming of 10 %, i.e. a confidence level of 0,90. A manufacturer declaring Class E2 need perform no FPC testing, unless he wishes to change this declaration. 6.3.4.4 For pentachlorophenol content (expressed in term of value) Where the manufacturer uses no pentachlorophenol containing materials, he shall continue to check, with a frequency defined in his FPC manual, that no such material is used. For pentachlorophenol containing materials, the manufacturer shall use the provisions of 5.3 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 conforming of 10 %, i.e. a confidence level of 0,90. A manufacturer declaring "PCP > 5 × 10-6 (ppm)" need perform no FPC testing, unless he wishes to change this declaration. 6.3.4.5 Breaking strength (expressed in term of maximum load) (does not apply to veneer floor covering)
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 % (with no individual test result more than
± 10 %) from that of the product used in the initial type evaluation (whether tested or using reference data). Tests shall be made according to indications given in 5.6. 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. 6.3.4.8 Biological durability (expressed in term of use classes) For biological durability, the manufacturer shall ensure that the timber species used in the finished flooring product remain the same or do not change to an extent which would change the declared use class. For natural durability the classification is given for species in EN 350-2. For a composite element and if a value has to be declared, it depends on the composition of the element. For conferred durability classes, no FPC testing is necessary as long as the wood used does not change and the preservative characteristics and the application method are maintained. For preservative use, the parquet manufacturer shall follow indications of internal control expressed by the preservative manufacturer. If the product, the characteristics of the product or the method of application of the preservative are different, the manufacturer shall repeat the initial type test using 3 samples. 7 Marking The marking shall include the relevant properties for the intended application (refer to 4.1 to 4.3) and shall be completed by the product standard information on marking. SIST EN 14342:2005
EN 14342:2005 (E) 12 The accompanying information shall be placed on the product itself, on a label attached to it, on the packaging or on the accompanying commercial documents. The order in which the list is presented clearly reflects a hierarchy of reference. The marking shall include: – a reference to this standard (EN 14342) and the information according to (a), (b) and (c) below; (a) marking requirements based on classes: – reaction to fire: A1fl, A2fl, Bfl, Cfl, Dfl,, Efl, or Ffl. and value of smoke production s1 or s2 where the class requires this; – formaldehyde class E1 or E2; – content of pentachlorophenol (no indication if pentachlorophenol ≤ 5 ppm and "PCP > 5 ppm" in all other cases); (b) marking requirements based on declared values: performance characteristics unit of declared value or class – breaking strength

General considerations regarding durability of wood
A.1 General precautions (extract from EN 335-2:1992, Annex 3) If the use class for a component when in use cannot be determined accurately, or when different parts of the same component are deemed to be in different classes, decisions should be taken with regard to the more severe of the possible use classes. Where a wood component is inaccessible or where the consequences of its failure would be particularly serious, it may be more appropriate to consider a more durable timber or a more intensive preservative treatment than is usual for the perceived use class. The different durability and treatability of sapwood and heartwood should always be considered. A.2 Natural or conferred durability of sound wood (extract from EN 335-2:1992, Annex 4) The natural durability of solid wood can depend to a large extent upon: – species, see EN 460; – the presence of heartwood or sapwood. Improved durability may be conferred on solid wood by preservative treatment. The methods of treatment that may be used depend upon: – species; – the presence of heartwood or sapwood; – the preservative product used and the penetration and retention values selected from EN 351-1. For the natural durability of wood, see EN 350-2. For the penetration and retention combinations available, see EN 351-1. For the performance of wood preservatives, see EN 599-1. SIST EN 14342:2005

Formaldehyde classes
B.1 Product to be tested When a product has to be tested, the test to be applied is EN 717-1 except for referring to EN 326-1 for test pieces so that the test is done only on the face exposed. For an initial type testing, one sample is required by type of product (type means same adhesive type, same finishing and same panel (if the panel has been itself controlled or characterised)). B.2 Materials to be tested Where formaldehyde-containing materials, particularly aminoplastic resins, have been added to the product as a part of the production process, the product shall be tested and classified into one of two classes: E1 or E2. The test requirements for both initial type testing and factory production control/continuous surveillance are laid down in Table B.1 for Class E1 products and Table B.2 for Class E2 products. NOTE 1 Boards of Class E1 can be used without causing an indoor air concentration greater than 0,1 x 10-6 (ppm) HCHO in conditions according to EN 717-1. The test requirement does not apply to wood flooring to which no formaldehyde containing materials were added during production or in post-production processing. Such products may be classified E1 without testing. The limit values for the formaldehyde Class E1 are given in Table B.1 and for Class E2 are given in Table B.2. NOTE 2 Experience has shown that to ensure compliance with the limits in Table B.1 the rolling average of the EN 120 values (see EN 326-2) found from the internal factory control over a period of ½ year should not exceed 6,5 mg HCHO/100g panel mass for particleboards and OSB or 7 mg HCHO/100g panel mass for MDF. NOTE 3 The corresponding upper requirement limits for Class E2 boards are found from the EN 120 or EN 717-2 factory production/external control tests. SIST EN 14342:2005
