Application Summary AI generated

This standard specifies the technical requirements, test methods, and inspection rules for cellular plastics used as thermal insulation materials in cryogenic environments, specifically for applications below -50°C. It is applied in industries such as liquefied natural gas (LNG), air separation, and cryogenic storage, where materials like polyurethane foam or polyisocyanurate foam are used to insulate pipes, tanks, and equipment. The standard ensures reliable performance in preventing heat ingress and maintaining structural integrity under extreme cold conditions.
