What is ASTM D523?
ASTM D523 is a standard test method for specular gloss. It is a direct measurement taken with a “gloss meter”. Typically measurements will be taken on a flat, homogeneous and clean surface. Micom offers ASTM D523 Gloss testing services as part of its Surface Coatings testing offering.
What is 60 degree gloss meter?
60° is referred to as the universal measurement angle and is the most commonly specified geometry in applications such as paints, coatings, plastics, automotive interiors and general manufacturing. It can be used as a basic gloss assessment for any surface from matt surfaces to mirror finish polished metals.
What is ASTM D4214?
The purpose of ASTM D4214 is to characterize the degree of chalking of an exterior paint by using a standard of reference or by reflectance measurements.
What does a gloss value of 60 mean?
60° glossmeter for measuring mid gloss finishes such as printed paper. Complies to ISO 2813 and ASTM D523 the main standards for measuring gloss of coatings. Low cost easy to use gloss meter.
What are the units for gloss?
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.
What causes glossiness?
It is one of the important parameters that are used to describe the visual appearance of an object. The factors that affect gloss are the refractive index of the material, the angle of incident light and the surface topography.
What are gloss levels?
A gloss finish indicates that it is shiny or glass-like. The gloss of a finish suggests a level of gloss from flat to gloss or ‘glossy’. The gloss of a surface is described as the reflection of light from the surface that is independent of color. This is also known as the “objective gloss”.
What is astastm D523?
ASTM D523 is a standard test method for specular gloss. It is a direct measurement taken with a “gloss meter”. Typically measurements will be taken on a flat, homogeneous and clean surface.
What is the difference between ASTM D523 specular gloss & ASTM d2244?
The following video is about the ASTM D523 Specular Gloss & ASTM D2244 Color Difference Calculation tests. The ASTM D523 measures the capacity of a surface to reflect light while the ASTM D2244 calculates the color tolerances and small colours differences between opaque surfaces.
What is ASTM d2457?
The ASTM D2457 standard test method is used to measure the gloss of solid plastics and plastic films (opaque and transparent both).
What is the gloss meter tri-angle used for?
The Gloss Meter Tri-angle is used to perform the gloss measurement of various types of materials such as paint, paper, ceramics, plastics, and metals. The compact and portable instrument measures the geometry 20°, 60° and 85°.
