No result of αp and αw shall be lower than the declared level. 4.3.11 Release of dangerous substances Thermal insulation products shall not release any regulated dangerous substances in excess of the maximum permitted levels specified in relevant European or national regulations.
NOTE 1 European test methods are under development. NOTE 2 See Annex ZA. 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

185.3.2 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 avoid any air gaps during testing. 5.3.3 Flatness after one-sided wetting – Conditioning procedure The conditioning procedure referred to in 4.3.8 is as follows:  place the test specimen in a water tank at (23 ± 5) °C, in such a way that partial immersion is 5 mm;  dispose a load on the test specimen to avoi
