T/CAS 237-2014 Pillow molding polyethylene storage tank
Basic Information
Scope
Scope: This standard specifies the terms and definitions, classification, requirements, test methods, inspection rules, marking, packaging, transportation, and storage requirements for storage tanks processed by rotational molding using polyethylene as the main raw material. This standard applies to stationary storage tanks used for storing chemical liquids with a density not exceeding 1.4 g/cm3 and a nominal volume of 0.1 m3 to 50 m3, provided that the tanks are placed under atmospheric pressure, free from any external loads, and operate at normal temperatures of -30°C to 60°C, with long-term operating temperatures not exceeding 40°C. This standard does not apply to rotational molding storage tanks processed using cross-linked polyethylene, nor to steel-plastic composite storage tanks processed using the rotational molding process. Main technical content: This standard specifies the terms and definitions, classification, requirements, test methods, inspection rules, marking, packaging, transportation, and storage requirements for storage tanks processed by rotational molding using polyethylene as the main raw material.
