ASTM B659 is the ASTM standard guide for measuring thickness of metallic and inorganic coatings, offering practical direction for evaluating coating buildup on a substrate. It is relevant wherever coating thickness must be checked for quality control, compliance, or product performance. By helping users select and apply appropriate measurement practices, this guide supports more consistent inspection results and clearer communication between suppliers, manufacturers, and specifiers.

Overview of ASTM B659

The official title, Standard Guide for Measuring Thickness of Metallic and Inorganic Coatings, indicates a technical document focused on measurement methods rather than material requirements. ASTM B659 is used to guide thickness evaluation for coatings where accurate readings are important to inspection and acceptance decisions. It is commonly referenced when a project calls for reliable measurement practices and a consistent approach to coating assessment across different parts, processes, or test environments.

Common use cases of ASTM B659

This guide is commonly used in coating inspection workflows where metallic or inorganic coatings must be measured on finished components, plated parts, or coated surfaces. It may support incoming inspection, in-process checks, final quality review, and supplier verification. ASTM B659 is also useful when procurement or technical documents need a shared reference for thickness measurement methods, helping reduce ambiguity when evaluating coated products and comparing results across teams or facilities.

Benefits of using ASTM B659

Using ASTM B659 can improve consistency in thickness measurement and help reduce disputes over coating evaluation. It supports more reliable quality control by giving users a recognized ASTM standard to reference during testing and inspection. For procurement and compliance work, the guide can help align expectations for how thickness is measured, reported, and reviewed. ASTM B659 also helps organizations manage risk by encouraging repeatable practices for coating assessment.
