To comply with this standard, products shall meet the requirements of 4.2, and the requirements of 4.3 as appropriate. NOTE 1 Information on additional properties is given in Annex C. One test result for a product property is the average of the measured values on the number of test specimens given in Table 5. NOTE 2 Apparent density is a useful parameter, among others, for the identification but it should not be used as a basis for the quality assessment of XPS products. Apparent density of XPS boards and billets, if voluntary declared by the manufacturer will be determined in accordance with EN 1602, Thermal insulating products for building applications – Determination of the apparent density. Apparent density of pipe sections, if voluntary declared by the manufacturer will be determined in accordance with EN 13470, Thermal insulating products for building equipment and industrial installations – Determination of the apparent density of preformed pipe insulation. Products manufactured from XPS can have the same thermal and mechanical properties at different densities. For this reason, product density is not quoted as requirement in this standard. 4.2 For all applications 4.2.1 Thermal conductivity For flat specimens, the thermal conductivity shall be based upon measurements carried out in accordance with EN 12667 or EN 12939 for thick products. For cylindrical specimens EN ISO 8497 shall be used as specified in 5.3.2.
In both cases, the thermal conductivity values shall be determined by the manufacturer and verified in accordance with EN ISO 13787, Subclause 5.3.1, and Annex B of this standard. They shall be declared by the manufacturer at reference mean temperatures covering the product service temperature range. The following conditions apply: the measured values shall be expressed with three significant figures; the declared conductivity curve shall be given as a limit curve, defined in EN ISO 13787; the value of the declared thermal conductivity, λD, shall be rounded upwards to the nearest
0,001 W/(m·K); SIST EN 14307:2010
EN 14307:2009 (E) 11 the lowest reference mean test temperature required is - 170 °C, where relevant. The declared equation/limit curve is the “declared reference” with three significant figures, that is to
0,000 1 W/(m.K) for λ values below 0,1 W/(m.K) and in 0,001 W/(m.K) for λ
values above 0,1 W/(m.K). This shall be used as a reference for the verification of the declaration. When thermal conductivity is declared as a table derived from the equation, rounding upwards to the next 0,001 W/(m.K) has to be done for the full range of the thermal conductivity. NOTE Determinations of the declared thermal conductivity of pipe sections, following EN ISO 8497, having joints in metering area, include the effects of these joints as defined in EN ISO 23993.
4.2.2 Dimensions and tolerances 4.2.2.1 Linear dimensions of boards The length, l, and width, b, shall be determined in accordance with EN 822, the squareness,Sb , in accordance with EN 824, and flatness, Smax, in accordance with EN 825.

The greater value applies.
NOTE Smaller tolerances may be declared by a producer. 4.2.3 Dimensional stability Dimensional stability under specified temperature and humidity conditions shall be determined in accordance with EN 1604. The test shall be carried out after storage for 48 h at (23 ± 2) °C and (90 ± 5) % relative humidity. The relative changes in length, û0l, in width, û0b, and in thickness, û0d, shall not exceed 2 %. SIST EN 14307:2010
EN 14307:2009 (E) 13 4.2.4 Reaction to fire of the product as placed on the market Reaction to fire classification of the product as placed on the market shall be determined in accordance with EN 13501-1 and the basic Mounting and Fixing rules given in EN 15715:2009. NOTE This classification is compulsory and always included in the CE marking label. EN 13501-1:2007, Table 1, is applicable to products applied to flat surfaces or to curved surfaces with a diameter greater than 300 mm. If a flat product which has a classification according to EN 13501-1:2007, Table 1, is used in a linear application, it does not require further classification. EN 13501-1:2007, Table 3, is applicable to products applied on linear objects or with a diameter below or equal 300 mm. 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. 4.2.5 Durability characteristics 4.2.5.1 General The appropriate durability characteristics have been considered and are covered in 4.2.5.2, 4.2.5.3 and 4.2.5.4. 4.2.5.2 Durability of reaction to fire against ageing/degradation and high temperature The reaction to fire performance of XPS products does not change with time within their range of service temperature. 4.2.5.3 Durability of thermal resistance against ageing/degradation The declared thermal conductivity of XPS products does not change with time. This is covered by 4.2.1 thermal conductivity, Annex B determination of the aged value of thermal conductivity and 4.2.2 dimensions and tolerances. 4.2.5.4 Durability of thermal resistance against high temperature The thermal conductivity of XPS products does not change with time at a high temperature within their declared operating temperature range. This is covered by 4.3.2 maximum service temperature (dimensional stability). 4.3 For specific applications 4.3.1 General If there is no intended requirement for a property described in 4.3, for a product in use, then that property does not need to be determined and declared by the manufacturer. XPS pipe sections and prefabricated ware are sawed or abraded from flat boards. If not specified hereafter, the declarations for the specific characteristics correspond to the flat boards used for their fabrication. 4.3.2 Maximum service temperature The maximum service temperature, ST(+), shall be determined in accordance with EN 14706. At the maximum service temperature, ST(+), no test result shall have a variation of dimensions exceeding ± 3 %. SIST EN 14307:2010
EN 14307:2009 (E) 14 The maximum service temperature, ST(+), shall be declared in levels with steps of 5 °C. The rate of increase of temperature shall be 50 °C/h. NOTE XPS pipe sections and prefabricated ware are sawed or abraded from boards. Consequently, the maximum service temperature, ST(+), should be determined only on flat boards, in accordance with EN 14706. In case of need, direct determination of maximum service temperature for prefabricated pipe shells should be carried out in accordance with EN 14707. 4.3.3 Minimum service temperature Minimum service temperatures within the scope of this standard but above 0 °C, need not be tested. For minimum service temperature within the scope of this standard, but below 0 °C, a test is necessary that shall be agreed upon between the parties. Where relevant, the minimum service temperature, ST(-), shall be declared in levels with steps of 5 °C, mentioning the test method used.
4.3.4 Compressive stress or compressive strength The compressive stress at 10 % deformation, σ10, or the compressive strength, σm, shall be determined in accordance with EN
