Overview

ISO 8124-3:2020/Amd 1:2023 is an important amendment to the widely recognized standard for toy safety maintained by the International Organization for Standardization (ISO). This standard addresses the safety of toys, specifically focusing on the migration of certain elements from toy materials. The 2023 amendment introduces updated limits on boron and other elements in slime, and revises the permissible barium content in modelling clay. These changes ensure toys are safer for children by aligning with the latest toxicological data and global safety practices.

Key Topics

• Element Migration Limits: This amendment updates maximum acceptable migration levels for boron in both modelling clay and slime, and raises the maximum limit of barium in modelling clay to better reflect comparative exposure across toy types.
• Definitions: New definitions clarify what constitutes “slime” and “modelling clay and putty” to support accurate application of the standard.
  • Slime: A water-based, viscous, gel-like play material manipulated by hand.
  • Modelling clay and putty: Flexible, mouldable materials used for handcrafting shapes and figures.
• Health Considerations:
  • Boron's limit is based on its reproductive and developmental toxicity, with the World Health Organization’s guidance used to justify stricter exposure thresholds for children.
  • The revised limit for barium corrects previously inconsistent requirements between modelling clay and finger paints, ensuring exposure margins remain within safe boundaries.
• Analytical Corrections: The amendment revises analytical correction percentages to account for measurement uncertainties across a wider range of element determinations.
• Lab Practices: The handling of toy samples is clarified, for example, stating slime should not be dewaxed prior to analysis, preserving accurate results for regulatory compliance.

Applications

• Manufacturers of Toys: Toy manufacturers must adhere to the updated migration limits for elements such as boron and barium in products like slime, modelling clay, and putties before placing these items on the market. Compliance is critical to safeguard child health and reduce legal risks.
• Testing Laboratories: Accredited laboratories performing chemical migration tests should follow the updated protocols and measurement corrections, ensuring results meet international safety standards.
• Regulatory Bodies and Importers: Governments and enforcement agencies utilize this amendment to evaluate imported and domestically produced toys, helping ensure only compliant products reach consumers.
• Product Designers: Toy designers must consider these substance migration limits early during material selection and formulation, especially for innovative toy materials like slimes and modeling compounds.

Related Standards

• ISO 8124-1: Safety of toys – Part 1: Safety aspects related to mechanical and physical properties
• ISO 8124-2: Safety of toys – Part 2: Flammability
• ISO 8124-3:2020: Safety of toys – Part 3: Migration of certain elements (original document, prior to amendment)
• EN 71-3: Safety of toys – Migration of certain elements (European counterpart standard)
• ASTM F963: Standard Consumer Safety Specification for Toy Safety (North American standard)

Practical Value

Implementing ISO 8124-3:2020/Amd 1:2023 helps toy sector stakeholders:

• Mitigate health risks by using up-to-date science for harmful chemical limits in children’s products.
• Demonstrate regulatory compliance for international trade and market acceptance.
• Promote consumer confidence through visible adherence to recognized toy safety standards.

For companies seeking global market access and parents prioritizing child safety, aligning with this amendment is essential for responsible, competitive, and safe product development.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
