3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB/T 28202-2011 and GB/T 13890-2008, as well as the following apply.
3.1
stone furniture
furniture totally made of stone or that made of stone at main components
Note: Stone contains natural stone and artificial stone.
3.2
natural stone
natural rock of a particular size or shape after being selected and processed.
Note: If the natural gap and cracks of natural stone are sealed during processing by cement or synthetic resin but the internal structure of stone material is not changed, such natural stone is also classified into the natural stone.
3.3
artificial stone
compounded material using high molecular polymer or cement or a mixture of the two as the bonding material and the crushed (powder) material of natural stone and / or natural quartz stone (sand, powder) or aluminum hydroxide powder as the main raw materials, adding pigments and other auxiliary, subjected to the procedure of mixing, solidifying, etc.
4 Classification
4.1 Classification by types of stone product composition:
a) natural stone;
b) artificial stone.
4.2 Classification by use functions:
a) tables;
b) chairs and stools;
c) storage units;
d) beds.
