Stone gloss meter manufacturers take you to understand what to pay attention to when evaluating stone gloss

  • Time of issue:2022-08-11

(Summary description)When using a gloss meter to evaluate the gloss of stone, you need to pay attention to the following matters:
1. Spectral characteristics of light source and detector. Stone gloss meter manufacturers tell you that the spectral power distribution of the light source should be standard A light source or standard D65 light source. The spectral characteristics of the detector should be equivalent to the standard visual observer sensitivity, that is, it should be consistent with the international standard visual function v(λ). When deviating from these general conditions, different measured values ​​are reflected in gloss measurements on coloured samples.

Information

When using a gloss meter to evaluate the gloss of stone, we need to pay attention to the following matters:
1. Spectral characteristics of light source and detector. Stone gloss meter manufacturers tell you that the spectral power distribution of the light source should be standard A light source or standard D65 light source. The spectral characteristics of the detector should be equivalent to the standard visual observer sensitivity, that is, it should be consistent with the international standard visual function v(λ). When deviating from these general conditions, different measured values ​​are reflected in gloss measurements on coloured samples.

2. The opening angle of the light source and the detector. Stone gloss meter manufacturers tell you that when measuring specular gloss, when the opening angle of the detector changes, the result of measuring the gloss value will also change. At present, the commonly used gloss meter measurement angles are mainly 20°, 60°, 85°, etc. Among them, 20° is suitable for measuring high-gloss objects, 60° is suitable for measuring most medium-gloss objects, and 85° is suitable for measuring low-gloss objects.
3. The uniformity and directionality of the sample surface. Stone gloss meter manufacturers tell you that when measuring the gloss of different stone surfaces, the uneven surface and texture differences will also affect the measurement results of the gloss meter. Therefore, it should also be fully taken into account when measuring.
The above information is the Stone gloss meter manufacturer's introduction and analysis of what to pay attention to when evaluating stone gloss, hope it helps you.
