New methods for measuring the migration of certain chemical elements from different categories of toy materials have been published in an EU standard by CEN, the European Committee for Standardisation.
The standard, published on 10 April, also sets out a method for determining the migration level of chromium VI from scraped-off toy materials such as paint. The limit was tightened from 0.2mg/kg to 0.053mg/kg by an EU Directive last year (Directive EU 2018/725) and will apply from 18 November.
The latest standard – EN 71-3:2019, Safety of Toys - Part 3: Migration of certain elements – covers requirements and test methods for the migration of 19 elements (see table).
| aluminium | antimony | arsenic | barium |
| boron | cadmium | chromium (III) | chromium (VI) |
| cobalt | copper | lead | manganese |
| mercury | nickel | selenium | strontium |
| tin | organic tin | zinc |
The standard also includes a modified method for testing organic tin compounds which, according to CEN, has an increased extraction yield improving the detection limit and repeatability.
CEN says other changes include:
Validated methods for filtration that improve the results and simplify filtration work in the laboratory; and the method for pH control ensures that the samples are always tested at the pH intended.
The standard is currently awaiting citation in the EU's Official Journal.
The current standard EN 71-3-213+A3: 2018 will be withdrawn by 31 October.
