Overview - ISO 19577:2019 (Footwear - Determination of Nitrosamines)

ISO 19577:2019 specifies a standardized laboratory method for the determination of 12 Nitrosamines potentially present in footwear and footwear components, using solvent extraction followed by gas chromatography with mass selective detection (GC‑MS). The method is applicable to rubber materials used in footwear (see ISO/TR 16178 for material scope) and includes sample preparation, purification, chromatographic analysis, result calculation and reporting requirements. The standard includes informative and normative annexes with target compounds, GC‑MS parameters, confirmation procedures and interlaboratory results.

Key topics and technical requirements

Scope: Quantitative determination of 12 Nitrosamines in footwear/rubber components (Annex A lists the substances and GC‑MS ions).

Sample preparation: Representative sample cut to <3 mm; typical test portion 5.0 g extracted with methanol using an ultrasonic bath (30 ± 2 min) under controlled temperature.

Concentration & cleanup: Combined methanol extracts are concentrated (rotary vacuum or N2 evaporator) and purified using a C18 solid‑phase extraction column, then reconstituted and filtered before analysis.

Chromatographic analysis: GC‑MS is used with full scan for qualitative identification and Selected Ion Monitoring (SIM) for quantitative analysis. External calibration (and optionally internal standards) are used; example LOQ is 0.5 mg/kg.

Quantification & reporting: Calculation formulas, linear calibration procedures, and rounding rules are specified. Results below LOQ should be reported as <0.5 mg/kg. Test reports must reference ISO 19577:2019 and include sample identification, results, confirmation method and any deviations.

Safety note: Nitrosamines are hazardous and potentially carcinogenic; appropriate laboratory safety and environmental controls are required.

Applications and who uses it

Testing laboratories performing compliance testing of footwear and components for harmful substances.

Footwear manufacturers and suppliers for incoming material control and product safety verification.

Regulatory authorities and conformity assessment bodies enforcing chemical safety limits in consumer products.

Quality assurance and product safety teams managing chemical risk in rubber-based shoe parts (soles, adhesives).

R&D and materials scientists developing low‑nitrosamine rubber formulations.

ISO 19577 supports reliable footwear testing, GC‑MS nitrosamine analysis, and regulatory compliance for chemical safety in footwear supply chains.
