This International Standard specifies requirements and methods of testing for four categories of rigid cellular
plastics thermal-insulation products for buildings. It covers rigid cellular plastics in the form of flat or profiled
boards, with or without natural skins. They may also be faced or laminated with foil, plastic or metal films or
sheets, mineral coatings, paper, cardboard or other materials.
This International Standard is not applicable to materials used for the thermal insulation of pipes and vessels,
for impact sound absorption or for acoustical insulation.
