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 reduction in thickness, ∆εd, shall not exceed 3,0 %. The relative changes in length, ∆εl, and width, ∆εb, shall not exceed 2,0 %. This test shall not be performed when the more severe test, described in 4.3.2 is used. 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.

This is covered by 4.2.1 thermal conductivity, 4.2.2 dimensions and tolerances and 4.2.3 dimensional stability or 4.3.2 maximum service temperature (dimensional stability). 4.2.5.4 Durability of thermal resistance against high temperature The thermal conductivity of FEF products does not change with time or when subjected to the declared maximum service temperature. 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 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. 4.3.2 Maximum service temperature The maximum service temperature, ST(+), for sheets and rolls shall be determined in accordance with EN 14706. For tubes it shall be determined in accordance with EN 14707 respectively.
At the maximum service temperature, ST(+), the mean value of relative change in thickness (reduction), ∆εd shall not exceed 7 %. The maximum service temperature, ST(+), shall be declared below 100 °C in steps of not less than 5 °C and above 100 °C in steps of not less than 10 °C. 4.3.3 Minimum service temperature The manufacturer of an insulation material can choose which minimum service temperature he intends to declare for his product.
This minimum service temperature does not represent any specific physical property and can not be determined by any single standardized test method.
If a minimum service temperature is declared by the manufacturer the following physical properties in line with European test standards have to be declared at the declared minimum service temperature:
a) Thermal conductivity as a function of temperature;
SIST EN 14304:2010+A1:2013
EN 14304:2009+A1:2013 (E) 13 b) Coefficient of thermal expansion as a function of temperature (see Annex B); c) Tensile strength and/or compressive strength and Young's modulus as a function of temperature as agreed between the parties.
Other physical properties may be agreed upon by the concerned parties in addition.
Using these temperature dependent physical data, the suitability of any specific insulation can be estimated at a given low operational temperature for industrial installations in relation to application related design features.
A low operational temperature cannot be below the minimum service temperature. The minimum service temperature, ST(-), shall be declared in levels with steps of 10 °C. Minimum service temperature within the scope of this standard but above 0 °C need not be tested. 4.3.4 Water absorption Short term water absorption by partial immersion, Wp, shall be determined in accordance with EN 1609 for sheets and rolls or by EN 13472 for tubes. Tests shall be run with specimens of ≥ 15 mm thickness from one sample each being representative for flat products and tubes. No te
