GB/T 4085-2015Semirigid polyvinyl chloride floor tiles (English PDF)

3.1 homogeneous floor tile

floor tile with the same composition, color and pattern in the product thickness direction

3.2 heterogeneous floor tile

polyvinyl chloride floor tile with multilayer structure, which is composed of wear-resistant layer and other layers, and may contain reinforcing layer or stabilizing layer, with the wear-resistant layer different from other layers in composition and function

4.1 Classification

Classification by structure:

a) homogeneous floor tile, with code of HT;

b) heterogeneous floor tile, with code of CT.

4.2 Grade

4.2.1 Grade of wear-resistant layer

The wear-resistant layer is classified into Grades T, P, M and F.

Note: Homogeneous floor tiles may be regarded as a whole wear-resistant layer.

4.2.2 Grade of use

See Annex A for grade of use.

4.3 Specification

See Table 1 for the minimum thickness specification of floor tiles.
