This European Standard specifies the requirements for factory made products of expanded polystyrene which are used for the thermal insulation of building equipment and industrial installations with an operating temperature range of approximately - 180 °C to + 80 °C. Modified expanded polystyrene polymers with a higher temperature resistance are also covered by this standard.Below an operating temperature of - 50 °C, special tests regarding the suitability of the product in the intended application are advised (e.g. liquefaction of oxygen). Manufacturers’ advice should be heeded in all cases.The products are manufactured in the form of faced or unfaced boards, rolls, lags, pipe sections or other 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 insulation systems and composite panels; the performance of systems incorporating these products is not covered.This standard does not specify the required level or class of a given property that should be achieved by a product to demonstrate fitness for purpose in a particular application. The classes and levels required for a given application can be found in regulations and invitations to tender.Products with a declared thermal conductivity greater than 0,060 W/(m·K) at 10 °C are not covered by this standard.This standard does not cover products for in situ insulation (for loose fill or poured insulation) or products for the insulation of the building structure.
