ČSN EN 14304

This European Standard specifies the requirements for factory made flexible elastomeric foam products which are used for the thermal insulation of building equipment and industrial installations with an operating temperature in the range of approximately - 200 °C to + 175 °C. Below an operating temperature of - 50 °C, tests regarding the suitability of the products in the intended application should be performed. Manufacturer's advice should be heeded in all cases. The products are manufactured in the form of sheets, tubes, 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 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 should 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 European Standard does not cover products for the insulation of the building structure. The normative part of this European Standard does not cover compressive stress (see D.5). This document is identifying those clauses of the standard which are needed for the compliance of the European Standard with the Construction Products Regulation (CPR). The main technical changes that have been made in this new edition of EN 14304 are the following: a) an addition to the foreword; b) an addition in Clause 3; c) a new 4.3.9; d) modification of 5.3.2; e) modification of Clause 7; f) modification of Clause 8; g) modification of Annex A; h) a new Annex ZA.
