BS EN ISO 18099:2022

This standard BS EN ISO 18099:2022 Thermal insulating products for building equipment and industrial installations. Determination of the coefficient of thermal expansion is classified in these ICS categories:

• 91.100.60 Thermal and sound insulating materials

This document specifies the equipment and procedures for determining the coefficient of linear thermal expansion. It is applicable to thermal insulating products within the temperature range ?196 °C to 850 °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.
