EN 71-3 Selenium Migration Testing
The European Standard EN 71-3 is a crucial document that sets safety requirements for toys, focusing on chemical aspects. Specifically, this section addresses the migration of certain elements from materials used in toys to ensure they do not pose health risks to children.
One critical aspect within this standard involves the testing of selenium (Se) migration from non-ferrous metal components used in toys. Selenium is a trace element that can be toxic if ingested, particularly by young children. The aim of this test is to assess whether there is an unacceptable level of selenium migrating into potentially accessible parts of a toy.
For this testing procedure, the specimen must undergo a simulated oral exposure period lasting 5 minutes. This reflects how a child might come into contact with certain parts of a toy. After this time, any selenium that has migrated from the metal surface is collected and quantified using appropriate analytical techniques such as inductively coupled plasma mass spectrometry (ICP-MS). The results are then compared against the limit values specified by EN 71-3.
The testing process requires precise sample preparation, which involves cleaning the specimen thoroughly to remove any surface contaminants that could interfere with accurate measurement. Once prepared, the specimen is placed in a container containing water according to the standard's instructions for the duration of the test period.
After the migration has occurred, the liquid surrounding the specimen is filtered and analyzed for selenium content. This analysis determines whether the amount of selenium that has migrated exceeds the permissible limit set forth by EN 71-3. Compliance with this limit ensures that toys meet European safety regulations and are suitable for use by children.
Given the importance of accurate testing in ensuring toy safety, it's essential to choose a laboratory with expertise in both the standard itself and the latest analytical techniques required for conducting these tests properly. Eurolab offers extensive experience and state-of-the-art facilities equipped specifically for performing such analyses.
Industry Applications
- Toys manufactured from non-ferrous metals like brass, bronze, or nickel alloy components may need to undergo selenium migration testing as specified by EN 71-3.
- Promotional items made using these materials where they could potentially come into contact with children might also require this type of analysis.
| Material Type | Metal Content | Selenium Migration Limit (mg/L) |
|---|---|---|
| Brass | Cu-Pb-Zn alloy | <0.1 mg/L |
| Bronze | Cu-Sn alloy | <0.1 mg/L |
These limits reflect the strict requirements set by EN 71-3 to minimize exposure risks associated with selenium in toys and similar products.
