T/CSTM 00896-2024 Industrial insulation products: Determination of linear thermal expansion coefficient by optical method
Basic Information
Scope
Scope: This document specifies an optical method for determining the linear thermal expansion coefficient of insulation products. This document is applicable to insulation materials with a temperature range of -196°C to 800°C, provided that it does not exceed the operating temperature limit of the insulation products. This document is not applicable to products that undergo irreversible dimensional changes due to water or phase transitions during the test process.
