Test method for specular gloss of ceramic products

1 Scope

This document describes the test method for the specular gloss of ceramic products. This document is applicable to the mirror gloss test of ceramic products, and is also suitable for evaluating the corrosion resistance, wear resistance, and other The impact of external factors on the surface of the product.

2 Normative references

The contents of the following documents constitute the essential clauses of this document through normative references in this document. For referenced documents without a date, only the version corresponding to that date applies to this document; for referenced documents without a date, the latest version (including all amendments) applies to This document.

3 Terms and Definitions

The terms and definitions defined in GB/T 5000 and JJG 696 and the following apply to this document. 3.1 Specular gloss Glossiness GS(θ) A relative measure of specular gloss. Note. The reference standard is black glass with a refractive index nD = 1.567.Assuming that its surface is ideally polished, the surface will reflect the natural light beam. And define the specular glossiness value at this time as 100.0 gloss units. 3.2 Glossiness plate Ceramic plate or polished black glass plate with smooth, uniform surface and good wear resistance. Note. Used in conjunction with a gloss meter.

4 Principles

Under the specified incident angle and beam conditions, the reflected light intensity of the ceramic surface in the mirror direction is compared with the glossiness plate in the mirror direction. The gloss value of the sample is measured by the intensity of reflected light in the direction.

5 Instruments and Equipment

5.1 Glossmeter The incident angle is 45° or 60°. The metrological performance of the instrument shall not be lower than Level 2 in JJG696.The optical principle and metrological performance requirements of the instrument are shown in Appendix A. ......
