Full title and description

ISO 16179:2025 — Footwear — Critical substances potentially present in footwear and footwear components — Determination of organotin compounds in footwear materials. This International Standard specifies a laboratory test method for the qualitative and quantitative determination of organotin compounds in footwear materials using gas chromatography coupled with mass spectrometry (GC‑MS).

Abstract

This document defines a validated analytical procedure to extract,, where applicable, derivatize and analyse organotin compounds in footwear materials and components (excluding metal hardware). The method is intended for use by testing laboratories and manufacturers to identify and quantify organotin species present in polymers, coatings, adhesives and other non‑metal footwear constituents.

Scope

Specifies a test method for the qualification and quantification of organotin compounds in footwear materials by gas chromatography coupled with mass spectrometry (GC‑MS). The procedure covers sampling, sample preparation (extraction and any required derivatization), instrumental analysis, calculation of results, and reporting requirements. It is applicable to all types of footwear materials and components except metallic hardware; users are referred to ISO/TR 16178 for material‑specific guidance.

Key topics and requirements

• Scope and applicability to footwear materials (excluding metal hardware).
• Sampling and sample‑preparation: extraction procedures appropriate for polymers, coatings and adhesives.
• Chemical derivatization steps where necessary to render organotin species amenable to GC analysis.
• GC‑MS operating parameters, calibration protocols and use of appropriate standards/internal standards.
• Performance criteria: limits of detection/quantification, recovery checks, repeatability and reproducibility expectations.
• Calculation and expression of results, units, and uncertainty considerations.
• Reporting requirements and statements on applicability/limitations of the method.

Typical use and users

Used by analytical and product testing laboratories, footwear manufacturers and material suppliers, conformity assessment bodies, regulatory authorities and product safety teams to detect and quantify organotin compounds in footwear components for product safety, regulatory compliance and quality control. The standard is referenced by industry stakeholders in announcements and technical communications upon publication.

FAQ

Q: What is this standard?

A: ISO 16179:2025 is an International Standard specifying a laboratory method for determining organotin compounds in footwear materials using gas chromatography–mass spectrometry (GC‑MS).

Q: What does it cover?

A: It covers sampling, extraction/derivatization where needed, instrumental GC‑MS analysis, calibration, performance requirements and reporting for organotin analysis in non‑metal footwear materials. Metal hardware is explicitly excluded and cross‑reference is made to ISO/TR 16178 for broader material guidance.

Q: Who typically uses it?

A: Analytical testing laboratories, manufacturers and suppliers of footwear and components, regulatory and compliance bodies, and certification/test houses. It is intended for routine testing, product development and regulatory compliance checks.

Q: Is it current or superseded?

A: Current — ISO 16179:2025 was published in March 2025 and supersedes ISO/TS 16179:2012 (the earlier technical specification was withdrawn).

Q: Is it part of a series?

A: Yes — it is part of the ISO work on critical substances in footwear (ISO/TC 216), which includes ISO/TR 16178 (lists and guidance) and other parts addressing specific substance groups and test methods (for example, ISO 16181‑1 for phthalates).

Q: What are the key keywords?

A: Footwear; organotin; GC‑MS; test method; critical substances; sample preparation; analytical chemistry; compliance.
