Overview

SIST EN ISO 9202:2026 is an international standard specifying the recommended range of fineness for precious metal alloys used in jewellery. Developed by the Slovenian Institute for Standardization (SIST) and aligned with ISO 9202:2026, this standard provides uniform criteria for determining and designating the precious metal content (fineness) in gold, silver, platinum, and palladium alloys. By referencing fineness in parts per thousand (‰) by weight, this document supports global harmonization and facilitates the reliable designation of jewellery and other articles made from precious metals.

It is important to note that individual countries may have specific legal requirements for labelling, marking, or stamping precious metal items. This standard operates alongside such regulations.

Key Topics

• Fineness Definition: Fineness refers to the minimum content of named precious metals in alloys, measured in parts per thousand by weight.
• Range of Fineness Values: Provides recommended fineness values for gold, platinum, palladium, and silver alloys, supporting standardized industry practices.
• Analytical Methods: Lists recognized ISO methods for accurately determining fineness, including gravimetric, potentiometric, and spectrometric analysis.
• Marking Guidance: Highlights the relevance of national legal requirements for marking and designation of precious metal jewellery.
• Standardization Benefits: Supports consistency, transparency, and comparability in the international precious metals trade.
• Alignment with Legal Frameworks: Encourages compliance with both the standard and applicable national or regional regulations regarding jewellery and precious metals.

Applications

The primary applications of SIST EN ISO 9202:2026 include:

• Jewellery Manufacturing: Assists manufacturers in selecting appropriate alloy compositions and ensures correct fineness marking, aiding in consumer trust and regulatory compliance.
• Quality Control: Enables laboratories and quality assurance teams to use validated analytical methods for fineness determination, reducing disputes and ensuring product reliability.
• Trade and Certification: Facilitates cross-border trade by providing a clear, internationally recognized system for comparing and certifying the precious metal content in jewellery items.
• Market Transparency: Helps retailers, assay offices, and purchasers by providing clear standards for product labelling and documentation.
• Consumer Protection: Sets minimum fineness criteria, ensuring customers consistently receive jewellery products with guaranteed precious metal content.

Related Standards

SIST EN ISO 9202:2026 is closely connected with several other international standards addressing testing methods and quality assurance in precious metals, including:

• ISO 11210: Gravimetric determination of platinum.
• ISO 11426: Fire assay (cupellation) for gold.
• ISO 11427: Potentiometry for silver.
• ISO 11490: Gravimetry for palladium.
• ISO 11494: ICP-OES method for platinum in alloys.
• ISO 11495: ICP-OES method for palladium in alloys.
• ISO 13756: Potentiometry using sodium or potassium chloride for silver.
• ISO 15093: Difference method using ICP-OES for high-purity gold, platinum, and palladium.
• ISO 15096: Difference method using ICP-OES for high-purity silver.
• ISO 18214: Difference method using SPARK-OES for high-purity precious metals.

By referencing these ISO methods, SIST EN ISO 9202:2026 provides a robust framework for the fineness determination and authentication of precious metal alloys in the jewellery industry.
