Thermal insulating products for building equipment and industrial installations - Determination of the coefficient of thermal expansion
This European Standard specifies the equipment and procedures for determining the coefficient of linear thermal expansion. The standard is applicable to thermal insulating products within the temperature range - 196 oC to 850 oC, subject to the possible temperature limitation of the test specimens. It shall not be used for products which during the test experience dimensional changes due to the loss of hydration water or which undergo other phase changes.
NOTE Because of its small dimensions the test specimen should be carefully selected to be representative of the product being tested.
