This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2010, and conflicting national standards shall be withdrawn at the latest by August 2011. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive 89/106/EEC. For relationship with EU Directive 89/106/EEC, see informative Annex ZA, which is an integral part of this document. Locally responsible authorities and contracting entities, who are bound by EU Directives to specify their requirements using European harmonized product standards, are allowed to demand additional properties outside the provisions of this standard if this is technically necessary because of prevailing operational conditions of the building equipment or the industrial installation projected or because of safety regulations. This European Standard contains three annexes: Annex A (normative), Factory production control; Annex B (informative), Additional properties; Annex ZA (informative), Clauses of this European Standard addressing the provisions of the EU Construction Products Directive. This document includes a bibliography. This European Standard is one of a series of standards for insulation products used in building equipment and industrial installations, but this standard can be used in other areas, where appropriate. In pursuance of Resolution BT 20/1993 revised, CEN/TC 88 have proposed defining the standards listed below as a European package of standards, setting 21 months after availability as the date of withdrawal (dow) of national standards which conflict with the European Standards of this package.

4.2 For all applications 4.2.1 Thermal conductivity For flat specimens 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. They shall be declared by the manufacturer according to the measuring standards mentioned above covering the product service temperature range. The following conditions apply: the measured value shall be expressed with three significant figures; the declared thermal 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). 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 the 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 The length, l, width, b, and thickness, d, for flat products shall be determined in accordance with EN 822 and
EN 823. Length, thickness and inside diameter, Di for pipe sections shall be determined in accordance with
EN 13467. Thickness, d, of slabs/boards, lamella products, mats, mattresses, quilts, rolls, and wired mats shall be determined in accordance with EN 823. The load shall be as shown in Table 3.
For wired mats the manufacturer may declare the thickness under loads of 50 Pa or 1 000 Pa. The thickness declaration shall be accompanied by the relevant thickness measurement load.
NOTE The choice of load for thickness measurement for wired mats is not related to the compression behaviour. No test result shall deviate from the declared values by more than the tolerances given in Table 1 or Table 2 for the labelled level or class.

NOTE 1 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. 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.
Manufacturers declaring Euroclass A1 without further test shall demonstrate by testing in accordance with EN 13820 that the products do not contain more than 1,0 % by weight of organic matter.
NOTE 2 The commission decision 96/603/EC of 4 October 1996 amended by the commission Decision 00/605/EC of 26 September 2000 gives the list of products to be considered as reaction to fire class Euroclass A1 without the need for testing. SIST EN 14303:2010
EN 14303:2009 (E) 13 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 MW products does not change with time or when subjected to the declared maximum service temperature. 4.2.5.3 Durability of thermal resistance against ageing/degradation The thermal conductivity of MW products does not change with time. 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 MW products does not change with time at a high 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(+) shall be determined in accordance with EN 14706 for flat specimens and EN 14707 for cylindrical specimens. At the maximum service temperature, ST(+) no test result shall: exceed a deformation under
