Remarks: a) The shade of color lump, spots, stain, holes etc. which are made intentionally for artistic effect or natural texture effect shall not be applied to this provision, they should not be regarded as a defect. With the same variety of Boyuejia material, each texture with natural grain as the foundation and barely repeat, this case should not be regarded as inconsistence of the product surface; Its color similar to natural soil color in the same color range with some irregular depth change, this case should not be regarded as chromatism. The bottom edge allows some rough selvedge. In order to highlight the characteristic of color mixture PK brick, its color shall change in the standard sample color range; There is 10% chromaticity difference allowed between monochromatic products and standard sample. b) The above requirement is only for in the area which the average temperature below zero in January every year. c) The above requirement is only for the thickness =3.5mm product, not for the thickness ＜3.5mm product, The thickness ＜3.5mm product can be regarded as a thick coating material.
