GB/T 34336-2017 Reinforced nanoporous aerogel products for thermal insulation 1 Scope This standard specifies the terminology and definition, classification and sign, requirements, test methods, inspection rules, marking, packaging, transportation and storage of reinforced nanoporous aerogel products for thermal insulation. This standard is applicable to reinforced nanoporous aerogel products for building and industrial thermal insulation. This standard can be used as a reference for other types of aerogel products. 2 Normative references The following referenced documents are indispensable for the application of this document.
