Application Summary AI generated

This standard specifies a test method for determining the coefficient of linear thermal expansion of thermal insulating materials used in industrial installations when exposed to sub-ambient (cryogenic) temperatures. It is applied in the quality control and performance evaluation of insulation products for pipelines, storage tanks, and equipment in industries such as petrochemical, liquefied natural gas (LNG), and refrigeration. The standard ensures that insulation materials maintain dimensional stability and thermal performance under extreme cold conditions.
