ASTM C533-17(2023)

Annotation of standard text ASTM C533-17(2023) :

This specification covers calcium silicate block and pipe thermal insulation for use on surfaces. Thermal insulation shall be of the following types: Type I; Type IA; and Type II. Calcium silicate thermal insulation shall consist principally of hydrous calcium silicate usually with the incorporation of fibrous reinforcement. The insulation shall conform to the physical requirements specified. Following test methods shall be performed: block insulation; pipe insulation; apparent thermal conductivity; linear shrinkage after heat soaking; flexural strength; compressive strength; mass loss by tumbling; hot surface performance; surface burning characteristics; stress corrosion performance; and moisture content by dry weight.
