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).

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
artificial stone
material made by mixing, coagulating and curing processes, etc. with high molecular polymer or cement or mixture of both as adhesive material and natural stone crushed (powder) material and/or natural quartzite (sand, powder) or aluminum hydroxide powder as main raw materials, and with pigment and other additives added, which mainly includes artificial stone-solid surface materials, artificial stone-agglomerated quartz and artificial stone-agglomerated marble
artificial stone formed by casting or vacuum molding or compression molding, with methyl methacrylate (MMA; commonly known as acrylic) or unsaturated polyester resin (UPR) as the matrix and aluminum hydroxide mainly as filling material, and with pigments and other adhesive materials added, whose scientific name is mineral-filled polymer composite which is referred to as solid surface material for short
Note: the composite material is non-porous and homogeneous: the composition throughout the whole thickness is uniform; they may be made into a continuous surface where seams are difficult to detect, with the surface of products capable of being restored by maintenance and renovation.
