EN ISO 2082:2017 PDF

Overview

EN ISO 2082:2017 (ISO 2082:2017) defines requirements for electroplated cadmium coatings with supplementary treatments on iron and steel. The standard specifies what purchasers must supply to electroplaters, and describes coating designation, appearance, thickness, conversion (e.g., chromate) and other supplementary treatments, adhesion, accelerated corrosion testing and heat‑treatment requirements before and after plating. It also includes informative guidance (Annex C) on corrosion resistance, rinsing/drying, bulk processing and dyeing of chromate conversion coatings.

Key topics and requirements

• Scope and exclusions: Applicable to protective cadmium electrodeposits for ferrous parts; not applicable to non‑fabricated sheet/strip/wire, close‑coiled springs, or coatings used for other than protective, lubricity, ductility, electrical conductivity and low contact resistance purposes.
• Information from purchaser: Essential and additional information to be supplied to the electroplater (material designation, required treatments, acceptance criteria).
• Designation and specification: Standardized designation for the coating and supplementary treatments to ensure clear procurement and quality control.
• Appearance and thickness: Requirements for visual appearance and methods for measuring coating thickness (see normative references).
• Supplementary treatments: Conversion coatings (including chromate and chromium‑free alternatives) and other finishes to improve corrosion resistance, lubricity and electrical contact properties.
• Adhesion and corrosion testing: Adhesion checks and accelerated corrosion testing (neutral salt spray among methods) with defined corrosion‑rating practice.
• Heat treatments: Stress‑relief heat treatment before cleaning/deposition and hydrogen‑embrittlement‑relief heat treatment after electroplating to mitigate embrittlement risks.
• Sampling and testing: Procedures for sampling small articles and acceptance testing; Annex B addresses thickness measurement on small parts.
• Safety/environmental considerations: Highlights toxicity of cadmium and restrictions on hexavalent chromium (noting REACH actions and availability of chromium‑free conversion coatings).

Applications and users

EN ISO 2082:2017 is used by:

• Electroplaters and plating shops specifying process controls and acceptance criteria for cadmium finishes.
• OEMs and suppliers in aerospace, defence, electrical contacts, fasteners and other sectors where cadmium’s combination of sacrificial corrosion protection, ductility, lubricity and low contact resistance is required.
• Quality, procurement and inspection teams for purchasing clauses, test plans and conformity assessment.
• Design and maintenance engineers selecting coatings where corrosion performance and electrical properties are critical.
