6.2 Initial type testing !!!!deleted text"""" !The initial type testing shall be performed to show conformity with 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 the purpose of the 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 values of Clause 5 are used. !Where wood and parquet 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 !manufacturer" 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 !factory production 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. !Any FPC system complying with EN ISO 9001:2000, and made specific to the requirements of this standard, is deemed to satisfy the requirements of FPC." 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 !manufacturer". 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 !ten" 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 SIST EN 14342:2005+A1:2008
EN 14342:2005+A1:2008 (E) 11 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 !products" 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 (e.g. some surface coated products) 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, used for classification, 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 A.1 or A.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 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) (only apply to self supporting floorings)"""" Where a manufacturer claims a breaking strength value, tests shall be made according to EN 1533 !deleted text". 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 of the wood and parquet flooring product is declared, tests shall be made according to the instructions given in 5.5. If a change in the product is made such that it would significantly affect the slipperiness performance of the product, the initial type test shall be repeated." 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 !± 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 !shall be 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 initial type test shall be repeated." SIST EN 14342:2005+A1:2008
EN 14342:2005+A1:2008 (E) 12 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 !characteristics" for the intended application (refer to 4.1 to 4.3) and shall be completed by the product standard information on marking. !The information shall be placed on the product itself, or on a label attached to it, or on the packaging or on the accompanying technical and/or commercial documents. This order in which the list is presented clearly reflects a hierarchy of preference." The marking shall include: – !a reference to this European Standard (i.e. EN 14342:2005+A1) and the information according to (a), (b) and (c), as follows:" (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: !

Such products may be classified E1 without testing. The limit values for the formaldehyde Class E1 are given in !Table A.1" and for Class E2 are given in !Table A.2".
