Refractory products. Methods of test for ceramic fibre products. Ingestion-build-48068 NOTE: This standard covers valves1 Scope This International Standard specifies methods for determining the thickness, bulk density, resilience, permanent linear change on heating, thermal conductivity, tensile strength and shot content of ceramic fibre products. It applies to ceramic fibre bulk, blankets, felts, mats, boards, papers and pre formed shapes with the exception of products delivered in a wet state. The application of the individual test methods is given in table 1, with
