The second edition eliminates and replaces the technically revised first edition (国际标准化组织 13803:2000). The major technical changes are:

我) symbols have been adapted to the revised version of ISO 2813;

乙) Introduction and principles clauses have been added;

C) Supplementary test conditions have been included in the test report;

d) 规范性参考文献已更新.

介绍
A high quality surface should have a clear and bright appearance. Microstructure can lead to a milky appearance. This effect is described as haze. High gloss surfaces with microscopic texture have low intensity diffuse light adjacent to the main reflection direction. Most of the incident light is in the direction of specular reflection, which will make the surface appear to have a high gloss of image forming quality, but with a milky haziness at the top.

The haze phenomenon can only be seen on high gloss surfaces. 所以, the 20° geometry is used in a similar way to the glossometer. The 20° gloss meter has an aperture range of 1,8 °. Two additional sensors next to the gloss detector measure the intensity of the diffuse light that causes haze. 因此, specular and scattered light are measured simultaneously. To better correlate with visual perception, haze is displayed on a logarithmic scale -the lower the haze reading, the better the surface.

1 范围
This standard specifies test methods for determining the haze of coatings. This method is suitable for haze measurement of non-textured coatings on flat and opaque substrates.

The use of a 20° geometry means that the method is closely related to the measurement of 20° gloss in ISO 2813. The application of the method aims to improve the distinction between high-gloss surfaces, for example in the field of dispersion properties assessment.

3 术语和定义

就本文件而言, 以下术语和定义适用.

3.1 阴霾
Milky white in high gloss or clear coating

[来源: 国际标准化组织 4618:2014, 2.137]

3.2 几何学
Identify haze measurements that use a specified Angle and a specified aperture

[来源: 国际标准化组织 2813:2014, 3.2, 修改的 – the term “光泽度” 已替换为 “haze”.

3.3 Haze value
The ratio of the light flux reflected and diffuse scattered from adjacent objects in the specular direction from specified light source and acceptor angles to the light flux reflected in the specular direction from a glass with specular reflectivity of 1,567, specified as 100 on a linear haze scale

笔记 1: The measurement of haze value is related to the measurement of gloss according to ISO 2813.
