Overview

EN ISO 18219-1:2021 - Leather: Determination of chlorinated hydrocarbons in leather - Part 1 specifies a chromatographic method for short‑chain chlorinated paraffins (SCCPs, C10–C13) in processed and unprocessed leathers. Published by CEN/ISO, this standard describes sample preparation, extraction, clean‑up and instrumental analysis to quantify SCCPs for regulatory compliance and quality control.

Key topics and technical requirements

Scope: Determination of SCCPs (chain length C10–C13) in leather samples.

Sample preparation: Extraction with n‑hexane in an ultrasonic bath at 60 °C for 60 minutes (as specified).

Clean‑up: Sulfuric acid treatment is used for sample clean‑up (replacing earlier SPE procedures).

Calibration: Procedure includes preparation of an SCCP calibration solution (example: 50 µg/ml with ~59% chlorine content) to compare sample chromatograms with a defined standard mixture.

Instrumental method: Primary analysis by GC‑ECNI‑MS (gas chromatography with electron capture negative ion chemical ionization mass spectrometry). The method uses multiple ion traces (four ion traces) for SCCP identification.

Alternative method: An LC‑MS/MS procedure is provided (Annex B) where users can demonstrate equivalent accuracy to the GC‑ECNI‑MS method.

Data processing: Guidance on evaluation, calculation, precision and reporting (including Annex C on peak shape evaluation).

Normative references: ISO 2418 (sampling location) and ISO 4044 (sample preparation) apply to sampling and test sample preparation.

Applications and practical value

Regulatory compliance: Supports conformity with EU regulations (REACH/Directive 2002/45/EC, Commission Regulation 2015/2030) and international obligations such as the Stockholm Convention listing of SCCPs as POPs.

Quality control: Routine testing by leather manufacturers and tannery laboratories to confirm absence or levels of SCCPs in finished articles.

Supply‑chain verification: Used by importers, retailers and compliance officers to verify supplier declarations and to prevent restricted substances in leather articles.

Environmental and safety monitoring: Analytical labs can apply the method to assess contamination risk and support remediation or reformulation decisions.
