What is ISO 8130-3 about?

ISO 8130 discusses Coating powders. ISO 8130-3 is the third part of the ISO 8130 multi-series and discusses the determination of density.

ISO 8130 specifies a liquid displacement pyknometer method for the determination of the density of coating powders. The method is based on a determination of the mass and the volume of a test portion.

Who is ISO 8130-3 for?

ISO 8130-3 on coating powders is useful for:

Paint manufacturers
Quality control personnel

Why should you use ISO 8130-3?

Density is a measure of mass per unit of volume, frequently expressed in g/cm3. It has been implied that a lower coating density means better coverage. In such an instance it is accepted that a given weight of an uncured coating with a lower density covers a greater area than does a higher density product.

ISO 8130-3 helps you in finding this density in coating powders using a liquid displacement pyknometer test. The test mentioned ISO 8130-3 helps you to find the density more precisely. ISO 8130-3 helps you manufacture high-quality paints and helps gain good consumer trust and confidence.

What’s changed since the last update?

BS EN ISO 8130-3:2021 supersedes BS EN ISO 8130-3:2010, which is withdrawn. BS EN ISO 8130-3:2021 includes some technical changes with respect to BS EN ISO 8130-3:2010. These include:

The use of acetone for cleaning the pycnometer has been deleted
The order of filling the pycnometer has been changed
The acceptable difference between the two results (Clause 9) is given as a percentage
The terms and definitions clause (Clause 3) has been added
The scope has been revised editorially, the text has been editorially revised, and the normative references have been updated
