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.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB/T 4132 and GB/T 5480 and the following apply.
3.1
aerogel
a kind of nanoporous solid material made by sol-gel method and dried by a method in which the liquid component of the gel has been replaced with a gas
3.2
reinforced nanoporous aerogel products for thermal insulation
nanoporous composite product made by sol-gel method to compsite with reinforced material and dried by a method in which the liquid component of the gel has been replaced with a gas
3.3
resilience rate
the recovery property of aerogel blanket which is compressed under certain pressure for a period of time. It is indicated by a ratio between the recovered thickness after unloading and the original thickness
