Overview
ISO 17881-1:2016 - Textiles - Determination of certain flame retardants - Part 1: Brominated flame retardants - is an international test method for identifying and quantifying selected brominated flame retardants (BFRs) in textile products using gas chromatography–mass spectrometry (GC‑MS). The method is applicable to all kinds of textile products and sets out sample preparation, analytical instrumentation and reporting requirements for laboratory testing.
Key topics and technical requirements
- Scope and principle
- Extraction of BFRs from textile specimens by ultrasonic-assisted extraction with toluene, followed by GC‑MS identification and quantification using an internal standard method.
- Target analytes
- A list of common brominated compounds covered, including mono‑ to decabromobiphenyls (MonoBB to DecaBB), polybromodiphenyl ethers (Tetra‑ to DecaBDE), and hexabromocyclododecane (HBCDD).
- Reagents and standards
- Use of analytical-grade reagents; decachlorobiphenyl specified as the internal standard.
- Apparatus
- Required equipment includes GC‑MS, ultrasonic generator (35–45 kHz), evaporator (50 °C water bath), filtration membrane (0.45 µm), and precision balance.
- Procedure highlights
- Representative specimen cut to ~1.00 g; extraction in 20 ml toluene (30 min), a second extraction with 10 ml toluene (15 min), combined extracts evaporated, reconstituted with internal standard and filtered prior to GC‑MS analysis.
- Calibration and calculation
- At least five calibration dilutions to build calibration curves; results expressed as mass ratio (µg/g) with blank correction.
- Performance data
- Annex A provides example GC‑MS parameters and typical ions; example detection limits are provided (commonly 5–10 µg/g for many BFRs).
- Quality and reporting
- Run blanks to check contamination; test report must reference ISO 17881‑1:2016, include sample identification, content of each flame retardant and any procedural deviations.
Applications and users
- Laboratories performing flame retardant testing for textiles and consumer goods.
- Textile manufacturers and finishers verifying product composition and quality control.
- Regulatory and compliance testing labs assessing presence of regulated BFRs in trade and import/export screening.
- Environmental and occupational testing groups monitoring brominated compound residues in textile waste or recycled fibers.
Related standards
- ISO 17881 series - Part 2 covers phosphorus flame retardants (ISO 17881‑2).
- Use ISO 17881‑1:2016 in conjunction with laboratory QA/QC practices and any jurisdictional regulatory limits when interpreting results.
