Introduction of JC/T 908-2013

Artificial stone 1 Scope This standard specifies the terms and definitions, product classification, specification and dimension, grade and mark, materials, requirements, test methods, inspection rules, packaging, marking, transport and storage of artificial stone (including artificial stone-solid surface materials, artificial stone-agglomerated quartz, artificial stone-agglomerated marble, etc.). This standard is applicable to table tops, walls, floors, ceiling materials, decorative surface materials and marked lines that use artificial stone-solid surface materials, artificial stone-agglomerated quartz and artificial stone-agglomerated marble, and reference may be made to it for artificial stones of other types and for other purposes as well as their products (such as wash basins and bathtubs). 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
