ASTM C584

Introducing ASTM C584 – Industrial Physics

ASTM C584 is a global ASTM standard test method that uses a glossmeter to measure the specular gloss of glazed ceramic whitewares and related products.

The gloss of an object, alongside its color, are important aspects of how we see and perceive a product.

Glossmeter testing is a useful part of the quality control process. It offers a point of reference, allowing manufacturers to ensure consistency across a range of applications.

What’s involved with glossmeter testing?

Using a glossmeter will determine the specular reflection or gloss of a surface. It projects a beam of light at a fixed angle and intensity onto a surface and then measures how much light is reflected at an equal and opposite angle. Glossmeter testing is commonly used to measure the gloss of paints and coatings as well as metals, papers and plastics.

A glossmeter tester will measure the gloss of a wide range of different surfaces and there are different geometries available for each. There are three main angles used to cover the range of gloss: 20-degree, 60-degree and 85-degree. Some industries, such as paper or ceramics, define their own degrees.

ASTM C584 glossmeter testing

This ASTM testing standard enables you to establish specular gloss limits for bright, semi-mat, and mat glazed surfaces.

Industry recognizes that specular gloss measurements don’t always correlate well with visual rankings of glossiness. This is because specular gloss is only one of several related appearance attributes that produce the sensation of gloss. However, this ASTM method has been designed to give enough accuracy for the intended purpose.

So, how can Industrial Physics improve your ASTM C584 testing?

Glossmeter – Sologloss & Polygloss

Our portable precision glossmeters are for production and laboratory settings. It is just what you need for glossmeter testing of automotive parts, paints and coatings.

This reliable glossmeter has a large memory capability; it will hold up to 2,000 readings with adjustable gloss limits. It features a visual and acoustic alarm and a calibration gloss standard integrated in a protective holder.

We ensured the quality of our glossmeter by taking thousands of readings on certified substrates to test stability, reliability, and durability – so you can be sure it will meet your needs.

TQC Sheen PolyGloss 20° / 60° / 85°

Our specialist paint testing brand ‘TQC Sheen’ makes two glossmeter models, both of which support your ASTM C584 testing: first up is the highly accurate Polygloss glossmeter, for angles of 20°, 60° and 85°.

TQC Sheen SoloGloss 60°

The second accurate gloss testing device made by TQC Sheen is the Sologloss glossmeter, with a 60° measuring angle for any surface – from mat to glossy.
