ASTM B322 is the ASTM standard that provides a guide for cleaning metals prior to electroplating, helping users prepare surfaces before coating operations. It addresses an important pre-treatment step that can affect plating quality, adhesion, and overall finish performance. For shops, labs, and quality teams, this technical document supports more consistent cleaning practices and better process control before electroplating begins.

What is ASTM B322?

ASTM B322, Standard Guide for Cleaning Metals Prior to Electroplating, is a practical reference for preparing metal surfaces before electroplating. Its purpose is to guide cleaning practices so contaminants that may interfere with plating are removed or reduced. The standard is commonly used as a process aid rather than a detailed product specification, so it helps users select appropriate cleaning approaches for a given metal and workflow. In that way, ASTM B322 supports consistent surface preparation before finishing.

Where is ASTM B322 used?

This standard is commonly used in electroplating operations, metal finishing facilities, and production environments where surface preparation is part of the coating process. It is relevant wherever metals must be cleaned before receiving a plated layer, including quality control and process development settings. ASTM B322 is also useful for teams evaluating cleaning steps, documenting procedures, or aligning pre-plating practices with an established ASTM guide. Its value is greatest when consistent surface cleanliness is needed before plating.

Why is ASTM B322 important?

ASTM B322 matters because cleaning quality can strongly influence the outcome of electroplating. A clear guide helps reduce variability in preparation steps, supports better compliance with internal procedures, and can improve repeatability across jobs. It also assists procurement, engineering, and inspection teams when comparing cleaning methods or reviewing process performance. By focusing attention on surface preparation before plating, ASTM B322 helps reduce the risk of adhesion problems and other finish defects.
