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 for mineral sands used in expanded perlite. This standard is only applicable to mineral sands used in the production of expanded perlite. This standard was drafted with reference to JC/T 809—2012 "Mineral Sands for Expanded Perlite". Compared with JC/T 809—2012, in addition to editorial amendments, the main technical changes are as follows: the nominal particle size range and grade division were modified (see Chapter 4); the determination methods for particle size, chemical components, and combustion loss were modified (see Chapter 5).
