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; It may refer to this standard 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
The material that is 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.
3.2
artificial stone-solid surface materials (solid surface materials)
The artificial stone that is 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.
according to specification and dimension allowable deviation, angle tolerance,
flatness and appearance quality.
4.4 Mark
4.4.1 Solid surface materials
The solid surface materials shall be marked in the order of product Chinese
name, English abbreviation of matrix resin, specification and dimension code,
nominal thickness, grade and this standard number.
Example: Type I Grade A solid surface material meeting the requirements of
this standard, with polymethyl methacrylate as matrix and a thickness of 12.0
mm shall be marked as:
Artificial stone-solid surface material PMMA/I 12.0 A/JC/T 908- 2013
4.4.2 Agglomerated quartz
The agglomerated quartz shall be marked in the order of product Chinese name,
English abbreviation of matrix resin, specification and dimension, grade code
and this standard number.
Grade B agglomerated quartz meeting the requirements of this standard, with
unsaturated polyester resin as matrix, a thickness of 16mm and a side length
of 3,050 mm×1,450mm shall be marked as:
Artificial stone-agglomerated quartz UPR 3050×1450×16 B/JC/T 908-2013
4.4.3 Agglomerated marble
The agglomerated marble shall be marked in the order of product Chinese
name, English abbreviation of matrix resin, specification and dimension, grade
code and this standard number.
Example: Grade A artificial stone-agglomerated marble meeting the
requirements of this standard, with unsaturated polyester resin as matrix, a
thickness of 16.5mm and a side length of 800 mm×800 mm shall be marked as:
