JIS Z8741-1997 《Specular glossiness -- Method of measurement》 Related products

The JIS Z8741-1997 standard specifies the method of measurement of specular gloss on smooth surfaces of industrial products. The standard covers gloss measurement at different incident angles (20 °, 45 °, 60 °, 75 °, 85 °), including 85 degree specular gloss, 75 degree specular gloss, 60 degree specular gloss, 45 degree specular gloss and 20 degree specular gloss. It is suitable for Coating, anodic oxidation aluminum film, plastic and other materials. It provides the calculation method of gloss and the determination of standard plane. It is an important tool for evaluating and comparing the surface Gloss of materials.
