Description (English):

This document reviews methods for measuring the thickness of metallic and other inorganic coatings on both metallic and non-metallic substrates (see Tables 1, A.1 and A.2). It is limited to tests already specified, or to be specified, in International Standards and excludes certain tests that are used for special applications.

Abstract

Overview - ISO 3882:2024 (Metallic and other inorganic coatings)

ISO 3882:2024 is an international review of established methods for measuring the thickness of metallic and other inorganic coatings on both metallic and non‑metallic substrates. The fourth edition reorganizes previous content, updates measurement uncertainty guidance, and adds modern techniques (for example, phase‑sensitive eddy‑current and the STEP coulometric method). It surveys both non‑destructive and destructive techniques and points users to appropriate International Standards for each method.

Key topics and technical coverage

Scope and purpose: Reviews methods already specified (or to be specified) in International Standards; excludes special‑application tests.
Non‑destructive methods - summarized with working principles and limitations:
- Split‑beam microscope (light section) (ISO 2128): for transparent/translucent coatings; typically accurate to within ~10%; not suitable for very thin (<2 µm), very thick (>100 µm) or very rough coatings.
- Magnetic methods (ISO 2178, ISO 2361): for non‑magnetic coatings on magnetic substrates or specific nickel systems; sensitive to substrate magnetic state, curvature and roughness; uncertainty
