ActiveThermal insulating products for industrial installations—Determination of the coefficient of linear thermal expansion at sub-ambient temperatures
工业用绝热制品 低温线性热膨胀系数的测定
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.
