Overview
SIST EN ISO 4524-6:1999 is a European and international standard that specifies a precise test method for detecting the presence of residual salts in electrodeposited gold and gold alloy coatings. This test is essential for ensuring the quality and performance of metallic coatings used in engineering, decorative, and protective applications. The method involves boiling the coated metal specimens in water with a known electrical conductivity to identify any increase caused by residual salts or other conductive impurities released from the coatings.
Developed by the International Organization for Standardization (ISO) and adopted by CEN, this standard provides manufacturers and quality control professionals with a reliable procedure for assessing contamination levels that can affect the durability and functionality of gold and gold alloy electrodeposited coatings.
Key Topics
Scope and Application
EN ISO 4524-6 applies specifically to metallic parts fully composed of metal and excludes composite materials combining plastics with metal coatings. It covers test procedures pertinent to electrodeposited gold and gold alloy coatings used widely in decorative and protective contexts.Test Principle
The main principle involves boiling coated specimens in water of accurately measured initial conductivity. Any increase in conductivity after boiling indicates the extraction of residual salts or other conductive contaminants trapped within or on the coating.Test Procedure
- Specimens of about 30 cm² surface area are cleaned and immersed in 100 ml of purified water (conductivity ≤ 100 µS/m).
- Specimens with smaller dimensions are boiled in a round-bottom flask with reflux condenser; larger specimens use a beaker with a water-cooled lid to minimize evaporation.
- Boiling lasts for 10 minutes, after which the water cools, and its conductivity is measured again.
- The increase in conductivity is calculated to assess contamination levels.
Apparatus Requirements
The test necessitates borosilicate glassware reserved exclusively for this determination, a conductivity meter for precise measurements, and apparatus to reduce evaporative losses during boiling.Reporting
Test reports must reference EN ISO 4524-6, include measurement results, note any unusual observations, and provide additional relevant information requested by clients or stakeholders.
Applications
Quality Control in Manufacturing
This standard is critical for manufacturers of gold-plated components to ensure that coatings meet stringent purity criteria and do not contain residual salts that might compromise corrosion resistance or electrical performance.Engineering and Electronics
Gold coatings are widely used in electronic connectors and contacts. Ensuring minimal residual salts improves reliability and prevents potential failures caused by ionic contamination.Decorative and Protective Coatings
For decorative uses, residual salts can affect appearance and long-term stability. EN ISO 4524-6 testing helps maintain high aesthetic and protective quality standards.Research and Development
Laboratories developing new electrodeposition formulations can apply this standard to validate processes and minimize salt entrapment within coatings.

ISO 4524-6 : 1988 IE) Foreword ISO (the International Organization for Standardization) is a worldwide federation of national Standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Esch member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, govern- mental and non-governmental, in liaison with ISO, also take part in the work. ISO col- laborates closely with the International Electrotechnical Commission (IEC) on all mat- ters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISO Council. They are approved in accordance with ISO procedures requiring at least 75 % approval by the member bodies voting. International Standard ISO 45246 was prepared by Technical Committee ISO/TC 107, Metallic and o ther inorganic cos tings. Users should note that all International Standards undergo revision from time to time and that any reference made herein to any other International Standard implies its latest edition, unless otherwise stated.
