BS ISO 23766:2022 Thermal insulating products for industrial installations. Determination of the coefficient of linear thermal expansion at sub-ambient temperatures
1 Scope
This document specifies the equipment and procedures for determining the coefficient
of linear thermal expansion at sub-ambient temperatures (−196 °C to 25 °C), subject to the possible temperature limitation of the test specimens.
It is not applicable to products which experience dimensional changes during the test
due to the loss of hydration water or which undergo other phase changes.
