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 tem-perature range – 196 °C to 850 °C, subject to the possible tempera-ture limita-tion of the test speci-mens. It shall not be used for products which during the test experien-ce 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 care-fully selected to be representative of the product being tested.
