ČSN EN 14307

This European Standard specifies the requirements for factory made extruded polystyrene foam products which are used for the thermal insulation of building equipment and industrial installations with an operating temperature in the range of approximately - 180 °C to + 75 °C.
Below an operating temperature of - 50 °C, special tests regarding the suitability of the material 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 faced or unfaced boards, pipe sections, segments and prefabricated ware.
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 insulating 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 0,060 W/(m˙K) at a mean temperature of 10 °C are not covered by this standard.
This European Standard does not cover products intended to be used for the insulation of the building structure nor for acoustical insulation.
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).
