Gloss index

This test method is used to determine the gloss properties of a surface. It helps to determine impact of external influences on the visual appearance of a component.

These stresses can include processing, after-treatment, light aging, weathering and temperature aging. The respective gloss level is measured using a reflectometer.

Measuring geometry:
20°, 60° and 85°
