DIN EN 14313:2013-04

This European Standard specifies the requirements for factory made flexible polyethylene foam products which are used for the thermal insulation of building equipment and industrial installations with an operating temperature in the range of approximately -80 °C to +150 °C. Tensile stress in the insulation product should be avoided when applying PEF. This is even more important when applying PEF on lines with operating temperatures between -50 °C and -80 °C. The tensile stress should be kept at the minimum by applying the foam "under pressure", that is, cutting the parts in a generous way. Manufacturer's advice should be heeded in all cases. The products are manufactured in the form of tubes, profiles, sheets, rolls and tapes with or without coating and/or self-adhesive backing and/or different closure systems. This European Standard describes product characteristics and includes procedures for testing, evaluation of conformity, marking and labelling. Products covered by this European Standard are also used in prefabricated thermal insulation systems and composite panels; the performance of systems incorporating these products is not covered. This European Standard does not specify the required level of a given property that shall be achieved by a product to demonstrate fitness for purpose in a particular application. The levels required for a given application can be found in regulations and invitations to tender. Products with a declared thermal conductivity greater than 0,050 W/(m · K) at 10 °C are not covered by this standard. This standard does not cover products for the insulation of the building structure. The normative part of this standard does not cover compressive stress (see Annex C, C.4). This standard differs from DIN EN 14313:2010-03 as follows: a) Table ZA.1 has been supplemented by "Water permeability"; b) ZA.2 has been supplemented. The standard has been prepared by CEN/TC 88 "Thermal insulating materials and products" secretariat: DIN, Germany. The responsible national committee at the Building and Civil Engineering Standards Committee is NA 005-56-69 AA "Dämmstoffe für betriebstechnische Anlagen in Gebäuden und in der Industrie (SpA zu CEN/TC 88/WG 10)" ("Thermal insulation materials for building equipment and industrial installations (Mirror Committee of CEN/TC 88/WG 10))".
