PU includes both PIR and PUR products. The products are manufactured in the form of boards. !This European Standard includes PU multi-layered insulation products, see Annex D." Products covered by this standard are also used in prefabricated thermal insulation systems and !composite insulation products"; the performance of systems incorporating these products is not covered. This standard describes product characteristics and includes procedures for testing, evaluation of conformity, marking and labelling. This standard does not specify the required level of a given property to be achieved by a product to demonstrate fitness for purpose in a particular application. The levels required for a given application are to be found in regulations or non-conflicting standards. Products with a declared thermal resistance lower than 0,25 m2„K/W or a declared thermal conductivity greater than 0,060 W/(m„K) at 10 °C are not covered by this European Standard. This standard does not cover in situ insulation products and products intended to be used for the insulation of building equipment and industrial installations (covered by EN 14308). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

16 NOTE 1 Referring to the designation code CC(i1/i2/y)1c, according to Clause 6, a declared level CC(3/2/25)40, for example, indicates a value not exceeding 2 % for compressive creep and 3 % for total thickness reduction after extrapolation at 25 years (i.e. 30 times three hundred and four days of testing) under a declared stress of 40 kPa. NOTE 2 Testing times. According to EN 1606, the procedure at 10, 25 and 50 years respectively requires the following testing times: Extrapolation time years Minimum testing time days 10 122 25 304 50 608 4.3.7 Water absorption 4.3.7.1 Short term water absorption Short term water absorption by partial immersion, Wsp, shall be determined in accordance with EN 1609.

No test result shall exceed the declared value. 4.3.8 Flatness after one-sided wetting Change in deviation from flatness after one-sided wetting shall be determined from measurements of flatness made in accordance with EN 825 before and after conditioning the specimen in accordance with 5.3.3. Both sides of the specimen shall be tested. The change in deviation from flatness for each side shall not exceed the value, given in Table 10, for the declared level.

All test results of
and/or all test results of Z shall be within the range declared by the manufacturer. Alternatively, for the declaration of the water vapour diffusion resistance factor,
of PU products, the value quoted in EN ISO 10456 may be used. 4.3.10 Sound absorption Sound absorption coefficient shall be determined in accordance with EN ISO 354. The sound absorption characteristics shall be calculated in accordance with EN ISO 11654 using the values for the practical sound absorption coefficient, .p, at the frequencies: 125 Hz, 250 Hz, 500 Hz, 1 000 Hz, 2 000 Hz and 4 000 Hz and the single number value for the weighted sound absorption coefficient, .w.

No result of .p and .w shall be lower than the declared level. 4.3.11 Release of dangerous substances !National regulations on dangerous substances may require verification and declaration on release, and sometimes content, when construction products covered by this standard are placed on those markets. In the absence of European harmonized test methods, verification and declaration on release/content should be done taking into account national provisions in the place of use. NOTE An informative database covering European and national provisions on dangerous substances is available at the Construction web site on EUROPA accessed through: http://ec.europa.eu/enterprise/construction/cpd-ds/." 4.3.12 Reaction to fire of the product in standardized assemblies simulating end-use applications Reaction to fire classification of products in standardized assemblies simulating end-use applications excluding pipe insulation, shall be determined in accordance with EN 13501-1 and the mounting and fixing rules given in EN 15715. This classification offers the opportunity to give a complementary and optional declaration on reaction to fire for standard test configurations of assemblies, which include the insulation product. The number of the selected test configuration of assembly (Table 5 of EN 15715:2009), which is used in the test, shall be quoted with the Euroclass. Detailed information about the test conditions and the field of application of the classification as stated in the reaction to fire classification report shall be given in the manufacturer’s literature. 4.3.13 Continuous glowing combustion NOTE A test method is under development and the standard will be amended when this is available. 5 Test methods 5.1 Sampling Test specimens shall be taken from the same sample with a total area not less than 1 m2 and sufficient to cover the needed tests. The shorter side of the sample shall not be less than 300 mm or full size of the product, whichever is the smaller. 5.2 Conditioning Conditioning of the test specimens shall be at least 6 h at (23 ± 5) °C unless otherwise specified in the test standard. In case of dispute, the test specimens shall be stored at (23 ± 2) °C and (50 ± 5) % relative humidity for 7 days prior to testing. For FPC no special conditioning of the test specimens is needed. 5.3 Testing 5.3.1 General Table 11 gives the dimensions of the test specimens, the minimum number of measurements required to get one test result and any specific conditions, which are necessary. The test may be performed on the unfaced/uncoated product, if the facing/coating is known to have no relevance to the test result. SIST EN 13165:2013+A1:2015

18 5.3.2 Thermal resistance and thermal conductivity Thermal resistance and thermal conductivity shall be determined in accordance with EN 12667 or EN 12939 for thick products and under the following conditions: — at a mean temperature of (10 ± 0,3) °C; — after conditioning in accordance with 5.2; — taking into account the effect of ageing according to Annex C. Thermal resistance and thermal conductivity may also be measured at mean temperatures other than 10 °C, providing that the accuracy of the relationship between temperature and thermal properties is well documented. Thermal resistance and thermal conductivity shall be determined directly at measured thickness. In the event that this is not possible, they shall be determined by measurements on other thicknesses of the product providing that: — the product is of similar chemical and physical characteristics and is produced on the same production unit, — and it can be demonstrated in accordance with EN 12939 that the thermal conductivity does not vary more than 2 % over the range of thicknesses where the calculation is applied. When measured thickness is used for testing of thermal resistance and thermal conductivity, the test thickness should be the smallest of the measured points on the test specimen (and not the mean) as far as possible to avo
