ISO has published the amendment ISO 8124-3:2020/Amd.1:2023 for the migration of certain elements in relation to toy safety. This revised standard is effective immediately.

In March 2023, the International organization for Standardization (ISO) published first amendment ISO 8124-3:2020/Amd.1:2023 ‘Safety of Toys – Part 3: Migration of certain elements – Amendment 1: Limits for boron and other elements in slime, and barium in modeling clay’.

The revision determines the migration of certain elements from toy materials and parts including antimony (Sb), arsenic (As), barium (Ba), cadmium (Cd), chromium (Cr), lead (Pb), mercury (Hg), selenium (Se) and boron (B). The maximum acceptable element migration limits of toy materials are listed in the below table.

This new revision of the standard includes some additional important updates:

- Adds new definition of “slime” (section 3.13)

- Introduces new meaning of modelling clay and putty (section 3.14)

- Includes new set of analytical corrections including boron (section 4.2)

- Clarifies slime is not to be dewaxed (section 9.8.1)

- Provides rationale to raise soluble barium limit in modelling clays from 250 mg/kg to 350 mg/kg and the justification for the maximum level of boron in modelling clay, putties and slimes (Annex D, D3)

The revised standard is effective immediately.
