The measurement scale, gloss units (GU), of a glossmeter is a scaling based on a highly polished reference black glass standard with a defined refractive index having a specular reflectance of 100GU at the specified angle.

A gloss unit (GU) is a measurement value of gloss described in international standards. 60: 0-1000 GU, 20: 0-2000 GU, 85: 0-199 GU

In the United States, three of the main standards of gloss measurement are the D523 specular gloss measurement, the D4039 reflection haze measurement of high-gloss surfaces, and the D4449 measurement of the difference between surfaces of similar appearance.

2023年11月29日 · What Is a Gloss Unit? What Industries Need to Measure Gloss? From High gloss, to semi-gloss, to matte surfaces, the gloss level of any given material or object has a direct impact on the human visual perception of that material or object.

Gloss Unit. The Gloss Unit (GU) is defined in international standards including ISO 2813 and ASTM D523. It is determined by the amount of reflected light from a glass standard of known refractive index. The measurement angles most commonly used for gloss are 20°, 60° and 85°.

Follow Rodda Paint’s easy-to-follow guide below on how to choose the appropriate gloss level to fit your aesthetic and practical needs. The terms GLOSS and SHEEN are often used interchangeably to describe the look of a Paint Finish, specifically the range of how glossy a …

2024年12月16日 · The unit of the gloss meter is called gloss unit. The international convention symbol is GS or GU, which is the abbreviation of Gloss unit. According to the JIS standard, the gloss unit can be written as a percentage or a number.

What is a gloss unit? The measurement scale, Gloss Units (GU), of gloss meters is a scaling based on a highly polished reference black glass standard with a defined refractive index having a specular reflectance of 100GU at the specified angle.

A gloss meter is typically used to measure the glossiness of an object's surface, with common gloss units being GU and %. GU stands for Gloss Units, which represents the numerical result obtained by the gloss meter, while % represents the relative gloss percentage compared to a standard sample.

To understand the reading of a gloss meter, you need to know that the measurement scales uses Gloss Units (GU). It assumes a highly reflective black glass as having a specular reflectance of 100GU, calibrating this as the upper end, while a perfectly matt surface would be 0GU.
