Thermal insulation materials maximum use temperature tester which is based on GB / T17430-1998 is used to evaluate the maximum operating temperature of loose-fill insulation materials, carpets, blankets, blocks, plates, prefabricated pipe insulation and some insulation products;
ASTM C411-82 "hot surface temperature insulation performance test method"
ASTM C447-85 "insulation maximum use temperature assessment methods."
ISO 8142: 1990 Appendix A "pre-determined maximum use of mineral wool pipe shell temperature of the test method."
