What is this standard about?

This international standard describes how to measure the thickness of coatings applied to a solid substance. It also supplies broader information on each measurement method and has annexes on measuring thicknesses on rough surfaces.

Who is this standard for?

It’s relevant to the paints, coatings and colour industries, specifically paint and coatings manufacturers.

Why should you use this standard?

It describes methods for measuring the thickness of coatings applied to a substrate including for determining wet-film thickness, dry-film thickness and the film thickness of uncured powder layers.

For each method described, it provides an overview of the field of application, existing standards and the precision. Information on measuring film thickness on rough surfaces is given in Annex B. Information on measuring film thickness on wooden substrates is given in Annex C.

What’s changed since the last update?

This is a technical revision which replaces the 2007 edition. The revisions are as follows:

  • Terms and definitions have been updated to ISO 4618 and ISO/IEC Guide 99
  • The principle has been revised
  • White-light interferometer has been added as method 6C
  • The terahertz method has been added as method 11
  • Existing methods have been adapted to the current state of metrology
  • Characterisation of the methods and procedures in Annex A have been revised
  • Information in Annex A on the precision of the individual methods has been adapted to current standards
  • References to test standards and constructions standards in Annex A have been updated
  • Former Clause 7 on measurement of the film thickness on rough surfaces has been moved to Annex B
  • Annex C, on factors which influence measuring accuracy when measurements are performed on wood, has been added
