Materials for high vacuum multilayer insulation of cryogenic vessel
1 Scope
This standard specifies the product types and models, raw materials, technical requirements, test methods, inspection rules, as well as marking, product end-of-manufacturing information, packaging, transportation and storage of common materials for high vacuum multilayer insulation of cryogenic vessel.
This standard is applicable to the insulation materials formed by alternately combining spacing materials and heat-resistant radiation shields used in the cryogenic vessel adopting high vacuum multilayer insulation mode.
