Scope
Main technical content: This standard specifies the terms and definitions, classification, grading and marking, requirements, test methods, inspection rules, and marking, packaging, transportation, and storage of expanded perlite. This standard applies to expanded perlite used as insulation materials within a temperature range of 73K to 1073K (-200°C to 800°C) and for the production of insulation, sound-absorbing, and fire-resistant products, as well as the preparation of lightweight construction mortars. Expanded perlite for other purposes may also be used as a reference. This standard references the standard issued by JC/T 209-2012. Compared with JC/T 209-2012, in addition to editorial changes, the main technical changes are as follows: the determination criteria for particle size and thermal conductivity have been modified (see Chapter 5).
