Full title and description

СТ ИСО 2808-1991 (ISO 2808:1991) — Paints and varnishes — Determination of film thickness. Russian-language edition of the ISO method for measuring the thickness of coating films on various substrates, providing procedures, instrument types and reporting requirements for quality control and inspection of paint and varnish films.

Abstract

This standard specifies methods for determining the thickness of dry films of paint, varnish and related coatings applied to substrates. It describes a range of measurement techniques (mechanical, optical, magnetic, eddy-current, destructive cross-sectioning and micrometers) and gives guidance on calibration, preparation of test specimens, measurement procedures, interpretation of results and reporting. The Russian edition reproduces the 1991 ISO text for use in Russian-speaking laboratories and industry.

General information

• Status: 1991 edition (national Russian edition of ISO 2808). Users should confirm current status with their national standards body; later ISO revisions or national replacements may exist.
• Publication date: 1991 (original ISO publication year; Russian adoption/translation published in 1991).
• Publisher: International Organization for Standardization (ISO); Russian-language edition adopted/published by the relevant national standards organization.
• ICS / categories: 87.040 — Paints and varnishes (coatings testing and inspection).
• Edition / version: ISO 2808:1991 (Russian edition).
• Number of pages: Approximately 16–32 pages (varies by printed translation/format).

Scope

The standard covers procedures for measuring the thickness of dried coating films on a variety of substrates and by different measurement principles. It aims to provide repeatable test methods suitable for laboratory and field quality control, including guidance on instrument selection, calibration methods, measurement locations and the statistical treatment of results. It does not attempt to specify performance limits for coatings, but provides the measurement basis used in specifications and acceptance testing.

Key topics and requirements

• Overview of measurement principles: mechanical (micrometer), magnetic, eddy-current, optical and cross-sectioning.
• Instrument calibration and verification procedures, including reference standards and zeroing techniques.
• Preparation of test specimens and selection of measurement points to ensure representative results.
• Detailed step-by-step measurement procedures for each technique and for different substrate types (ferrous, non‑ferrous, non-conductive).
• Requirements for recording results, reporting formats and statistical evaluation (averages, range, number of readings).
• Guidance on limitations of each method, measurement uncertainty and interpretation of anomalous readings.

Typical use and users

Used by paint and coatings manufacturers, quality control laboratories, third-party inspection bodies, construction and marine coating contractors, automotive and industrial maintenance teams, and research organizations. Typical applications include incoming inspection, process control during production, acceptance testing at delivery or after application, and failure investigation where coating thickness is a factor.

Related standards

Commonly used alongside other coating and measurement standards — for example, standards that specify particular measurement methods on specified substrate types, later revisions of ISO 2808, and national standards for coating thickness measurement. Users often reference method-specific standards and product-specification documents when applying results from ISO 2808.
