Overview
ISO 8124-6:2023 - Safety of toys, Part 6: Certain phthalate esters is a method standard for the laboratory determination of key phthalate esters in toys and similar products. It specifies sampling, extraction and analytical procedures (including GC‑MS analysis and calibration options) for quantifying DIBP, DBP, BBP, DEHP, DNOP, DINP and DIDP. The method is validated for PVC and PU plastics and representative paint coatings, and can be extended to other phthalate esters or product categories with appropriate validation.
Keywords: ISO 8124-6:2023, phthalate esters, toy safety, phthalates in toys, phthalate testing method
Key Topics
- Target analytes: DIBP, DBP, BBP, DEHP, DNOP, DINP, DIDP (with allowance for other phthalates if validated).
- Scope of materials: plastics, textiles, coatings and liquids (validated for PVC, PU and some coatings - see Annex B).
- Sampling and test portions: rules for individual and composite test portions; composite test design and mathematical model (Annex D).
- Extraction methods: multiple extraction routes (Methods A, B, C) and optional Soxhlet/solvent/ultrasonic procedures (Annex C, E).
- Analytical technique: GC‑MS identification and quantification with external (ES) or internal standard (IS) calibration; example GC‑MS conditions provided (Annex F).
- Quality control: requirements for limit of quantification (LOQ), method blanks, recovery checks, calibration verification and precision (Annex B).
- Calculations & conformity: explicit formulas for individual and composite test results, including maximum-concentration assessments.
- Practical details: sample weighing, extract clean‑up, final solution volume adjustments and reporting requirements.
Applications
Who uses ISO 8124-6:2023 and why:
- Testing laboratories - for accredited phthalate testing and routine conformity assessment of toys.
- Toy manufacturers & suppliers - to verify material compliance and control phthalate content in PVC/PU/plasticized components and coatings.
- Regulators & market surveillance - to harmonize enforcement testing protocols and compare results across jurisdictions.
- Importers & retailers - to ensure product batches meet national or regional phthalate restrictions.
Practical benefits include standardized sampling, reliable GC‑MS workflows, composite testing for efficient batch screening, and documented QC procedures for reproducible results.
Related standards

- ISO 8124-1:2022 referenced for mechanical/physical safety context.
Note: ISO 8124-6:2023 provides the test method only; it does not set concentration limits - users should refer to applicable national or regional phthalate restrictions when assessing conformity.
