Описание (английский):

This document describes methods for measuring the thickness of coatings applied to a substrate. Methods for determining wet-film thickness, dry-film thickness and the film thickness of uncured powder layers are described. For each method described, this document 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.

Overview

ISO 2808:2019 - Paints and varnishes - Determination of film thickness - defines standardized methods for measuring the thickness of coatings applied to substrates. It covers procedures for wet‑film thickness, dry‑film thickness and the thickness of uncured powder layers, and reports on the field of application and precision for each method. The standard also includes guidance for measuring on rough surfaces (Annex B) and wooden substrates (Annex C), plus requirements for the test report.

Keywords: ISO 2808, film thickness, coating thickness measurement, paints and varnishes, wet-film thickness, dry-film thickness, powder coatings.

Key topics and technical scope

Scope and definitions: Terms and definitions used in film thickness measurement.

Wet‑film measurement methods:

Mechanical gauges (comb, wheel, dial)
Gravimetric (mass difference)
Photothermal techniques

Dry‑film measurement methods:

Mechanical thickness difference and depth gauging
Surface profile scanning and cross‑sectioning
Optical methods (white‑light interferometry, wedge cut)
Magnetic methods (magnetic pull‑off, magnetic‑flux, magnetic‑induction, eddy‑current)
Radiological (beta backscatter)
Photothermal and acoustic (ultrasonic reflection)
Electromagnetic (terahertz)

Uncured powder layer methods:

Gravimetric, magnetic, photothermal approaches adapted for powder films

Precision and field of application: For each method ISO 2808 provides an overview of suitable substrates, limitations and expected precision.

Annexes and reporting:

Annex A: overview of methods
Annex B: measurement on rough surfaces
Annex C: factors affecting measurements on wood
Section on test report content and documentation

Practical applications and users

Quality control and acceptance testing in coating manufacture, automotive, marine, industrial, architectural and wood coatings sectors.

Process control on production lines (wet or dry measurements) and laboratory R&D for new paint systems.

Inspection and compliance checks for corrosion protection and regulatory specifications.

Typical users: coating formulators, QC technicians, inspection bodies, third‑party testing labs, specifiers and contract applicators.

Related standards (if applicable)

ISO 2808 is part of a family of paint and coating test standards. Users often consult complementary national or international standards (for example, ASTM methods and other ISO coating test standards) for cross‑reference and additional procedural detail.

ISO 2808:2019 helps organizations select appropriate coating thickness measurement methods, understand limitations for different substrates, and document results consistently for reliable quality assurance and compliance.
