This European Standard specifies the requirements for factory made phenolic 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 + 120 °C. NOTE Below an operating temperature of - 50 °C, special tests regarding the suitability of the products in the intended application are advised (e. g. liquefaction of oxygen). Manufacturer's advice should be heeded in all cases. The products are manufactured in the form of blocks, faced or unfaced, boards, pipe sections, segments and prefabricated ware. This 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 insulating systems and composite panels; the performance of systems incorporating these products is not covered. This 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 in situ-insulation (blowing or pouring) or products for the insulation of the building structure. This standard does not cover the following acoustical aspects: direct airborne sound insulation and impact noise transmission index.
