This document specifies a method for the determination of the content of specific phthalates (see Annex A) by pyrolyzer/thermal desorption gas chromatography-mass spectrometry (Py/TD-GC-MS). This document is applicable to all types of footwear materials except textiles. NOTE See also CEN/TR 16417 for a list of the specific phthalates to which this document applies.

Overview - EN ISO 16181-2:2021 (Footwear, Phthalate determination)

EN ISO 16181-2:2021 specifies a solvent-free analytical method for determining phthalates in footwear and footwear components (excluding textiles). The standard defines a direct thermal extraction approach using a pyrolyzer/thermal desorption gas chromatography–mass spectrometry (Py/TD‑GC‑MS) system to separate and quantify specific phthalate compounds (see Annex A and CEN/TR 16417 for the list). This edition replaces CEN ISO/TS 16181:2011 and introduces a new technique complementary to ISO 16181-1 (solvent extraction).

Key topics and technical requirements

Analytical principle: direct introduction of the sample into a pyrolyzer; thermal desorption of phthalates; transfer to GC column and detection by MS.

Scope: applicable to all footwear materials except uncoated textiles and metallic parts.

Apparatus: requirements include a Py/TD accessory capable of 40–500 °C and a programmable heating rate (approx. 1 °C to 100 °C per minute), a GC‑MS, cryogenic mill for sample preparation, micro‑tools, and precision balance.

Reagents & calibrants: use GC‑grade n‑hexane for preparing calibration solutions, high‑purity helium carrier gas, and certified phthalate stock/standard solutions (details in Clause 6 and Annex A).

Procedure elements: sample preparation, calibration, chromatographic parameters, qualitative/quantitative MS analysis, calculation of phthalate content, performance verification and detection limits.

Documentation: requirements for the test report and informative annexes (sampling guidelines, chromatography parameters, chromatogram examples, method verification).

Practical applications and users

This standard is aimed at laboratories and stakeholders involved in footwear safety, compliance and quality control:

Test laboratories performing regulatory or voluntary screening for phthalates in shoes and components.

Footwear manufacturers and component suppliers validating raw materials and finished products for chemical safety.

Regulatory bodies and conformity assessors enforcing limits for restricted substances in consumer goods.

R&D and materials scientists adopting Py/TD‑GC‑MS for rapid, solvent‑free screening and method comparison (ISO 16181‑2 vs ISO 16181‑1).

Benefits include simplified sample handling, avoidance of solvent extraction, reduced chemical waste, and suitability for a wide range of footwear materials.
