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
33、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
34、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 Fr
35、ee 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 floori
36、ng 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; Licensed Copy: AUB User, na, Thu May 03 04:48:08 GMT+00:0

38、sses in which a product may be used are specified in EN 335-1 and EN 335-2. See also Annex A. 5 Determination of the performance characteristics 5.1 Reaction to fire Products meeting the definition given in Table 1 are considered to be classified without further testing in the class(es) shown. Other
39、 products shall be tested and classified (as flooring) in accordance with EN 13501-1 with, in addition to any specific provisions on mounting and fixing given in the test standards, the products being mounted and fixed in a manner representative of their intended end use.

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 chem
48、ical 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 so
49、ft 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.
