W/(m·K);  the lowest reference mean test temperature required is - 170 °C. The declared equation/limit curve is the "declared reference" with three significant figures, that is to 0,000 1 W/(m·K) for values below 0,1 W/(m·K) and in 0,001 W/(m·K) for 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 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 the metering area, include joints as defined in EN ISO 23993. 4.2.2 Dimensions and tolerances 4.2.2.1 Linear dimensions The length, l, width, b, and thickness, d, of sheets, rolls and tapes shall be determined in accordance with EN 822 and EN 823.

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 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. EN 13501-1:2007, Table 3, is applicable for products applied on linear objects or with a diameter below or equal 300 mm. SIST EN 14304:2010+A1:2013

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;
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 test results of the water absorption Wp, shall exceed 0,1 kg/m2 (WS01). 4.3.5 Water vapour diffusion resistance The water vapour transmission properties shall be determined in accordance with EN 12086 for flat products and in accordance with EN 13469 for tubes and declared as the water vapour diffusion resistance factor, µ. The Water vapour diffusion resistance factor (µ.) shall be declared in levels (MU) with steps of 1 000 up to a value of 15 000. No value shall be less then the declared level (e.g. MU 1 000 (µ ≥ 1 000), MU 15 000 (µ ≥ 15 000) etc.). NOTE 1 The water vapour transmission property and the water vapour diffusion resistance factor, µ, are a function of temperature, see Annex D. NOTE 2 Alternatively, for the declaration of the water vapour transmission properties, the values quoted in
EN ISO 10456 may be used. 4.3.6 Trace quantities of water soluble ions and the pH-value Trace quantities of water soluble chloride, fluoride, silicate and sodium ions and the pH-value shall be determined in accordance with EN 13468. The manufacturer shall declare one or more as appropriate as levels in mg/kg of product and the pH-value as levels in steps of 0,5. For chloride and fluoride, no test result shall exceed the declared value. For silicate and sodium, no test result shall be below the declared value. For the pH-value, no test result shall deviate from the declared value by more than 1,0. NOTE
Due to the fact that traces of halogens may be found in halogen-free Flexible Elastomeric Foam material caused by the inevitable impureness of compounds, the term “halogen-free” should be determined according to DIN/VDE0472-815 (Testing of cables and insulated conductions – halogen-freeness): “plastic materials are halogen-free if the sum of their amount of chloride, bromine and iodine is less then 0,2 % and the amount of fluoride less then 0,1% by weight”. 4.3.7 Structure-borne sound transmission Structure-borne sound transmission shall be determined in accordance with EN 14366 and/or EN ISO 3822-1. SIST EN 14304:2010+A1:2013

2,0 l/s. For comparison the LSC,A of the uninsulated pipe shall also be declared. 4.3.8 Sound absorption The sound absorption coefficient shall be determined in accordance with EN ISO 354 but always without a plenum. The sound absorption characteristics shall be calculated in accordance with EN ISO 11654 using the values for the practical sound absorption coefficient, αp, 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, αw (weighted sound absorption coefficient). αp and αw shall be rounded to the nearest 0,05 (αp > 1 shall be expressed as αp = 1) and declared in levels with steps of 0,05. No result of αp and αw shall be lower than the declared level. 4.3.9 Release of dangerous substances NOTE See Annex ZA. 4.3.10
Continuous glowing combustion Where subject to regulation a manufacturer shall declare the continuous glowing combustion according to national test method where available. NOTE
A European test method is under development and the standard will be amended when this is available. 5 Test methods 5.1 Sampling Flat test specimens shall be taken from the same sample with a total area of not less than 1 m2 or one full-sized sheet and sufficient to cover the needed tests. The shorter side of the sample shall not be less than 300 mm or the full size of the product, whichever is the smaller. Pipe section specimens shall be taken from a sample consisting of at least three full size sections. 5.2 Conditioning No special conditioning of the test specimens is needed 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 at least
6 h prior to testing. 5.3 Testing 5.3.1 General Table 2 gives the dimensions of the test specimens, the minimum number of test specimens required to get one test result and any specific conditions, which are necessary. Self-adhesive products shall be tested without the release liner. The test may be performed on the unfaced/uncoated product if the facing/coating is known to have no influence on the property.
