GB/T 11420-2024 《Vitreous and porcelain enamels—Test method of specular glossiness》 Related products

The GB/T 11420-2024 standard specifies the test method for the surface Glossiness of enamel products and porcelain enamel layers. The standard applies to the evaluation of the brightness of the surface of enamel products and porcelain enamel layers, and represents Glossiness by numerical value. Glossiness refers to the degree of light reflected by the surface and is a physical quantity that measures the luminance of the surface light. The standard requires the use of Glossiness Meter and Glossiness Board for testing, and refers to JJG 696 "Mirror-to-Glossiness Meter and Glossiness Board Verification Procedure" for verification. Through these measurements, the surface Glossiness of enamel products and porcelain enamel layers can be accurately assessed to ensure that the product meets the relevant mass requirements and technical specifications.
