EN 71-3 Migration of Certain Elements Testing for Toys | Laboratory Analysis by METS Laboratories
Introduction
Children often place toys in their mouths, creating the potential for exposure to hazardous substances that may migrate from toy materials. To protect children's health, toy materials must be evaluated for the release of certain toxic elements under conditions that simulate ingestion.
EN 71-3 is a key European toy safety standard that specifies limits and test methods for the migration of certain elements from toy materials. Compliance with EN 71-3 is mandatory for toys sold in the European Union and forms part of the requirements for CE marking under the Toy Safety Directive (2009/48/EC).
Professional laboratories such as METS Laboratories perform EN 71-3 testing to help manufacturers ensure product safety, regulatory compliance, and market access.

What is EN 71-3?
EN 71-3: Safety of Toys – Migration of Certain Elements
The standard specifies methods for determining the migration of toxic elements from toy materials when exposed to conditions that simulate contact with stomach acid after ingestion.
The test evaluates the release of regulated elements from:
Importance of EN 71-3 Testing
EN 71-3 testing helps manufacturers:
Failure to comply may result in market restrictions, recalls, or regulatory action.
Regulated Elements in EN 71-3
The standard regulates the migration of the following elements:
| Element | Symbol |
|---|---|
| Aluminium | Al |
| Antimony | Sb |
| Arsenic | As |
| Barium | Ba |
| Boron | B |
| Cadmium | Cd |
| Chromium (III) | Cr(III) |
| Chromium (VI) | Cr(VI) |
| Cobalt | Co |
| Copper | Cu |
| Lead | Pb |
| Manganese | Mn |
| Mercury | Hg |
| Nickel | Ni |
| Selenium | Se |
| Strontium | Sr |
| Tin | Sn |
| Organic Tin | Various |
| Zinc | Zn |
The permissible migration limits vary depending on the toy material category.
Material Categories
EN 71-3 classifies toy materials into three categories:
Category I
Dry, brittle, powder-like, or pliable materials:
Examples:
Category II
Liquid or sticky materials:
Examples:
Category III
Scraped-off materials:
Examples:
Each category has specific migration limits.
Principle of the Test
Toy materials are prepared according to the standard and subjected to extraction using a simulated gastric acid solution.
The extraction process mimics the release of elements that may occur if a child ingests toy material.
The extracted solution is then analyzed to determine the concentration of migrated elements.
Laboratory Equipment
Typical laboratory equipment includes:
These instruments provide highly accurate measurement of trace elements.
Test Procedure
Sample Preparation
Extraction
The prepared sample is extracted using hydrochloric acid under controlled conditions.
The extraction simulates gastric acid exposure.
Instrumental Analysis
The extract is analyzed for the regulated elements using:
Evaluation
Measured concentrations are compared with the migration limits specified in EN 71-3.
Common Sources of Restricted Elements
Restricted elements may originate from:
Proper raw material control is essential for compliance.
Benefits of EN 71-3 Testing
Manufacturers benefit from testing by:
Conclusion
EN 71-3 Migration of Certain Elements is one of the most important chemical safety standards for toys. The standard evaluates the potential release of toxic elements from toy materials under simulated ingestion conditions, helping to protect children's health and ensure regulatory compliance.
Professional laboratories such as METS Laboratories use advanced analytical techniques, including ICP-OES and ICP-MS, along with standardized extraction procedures, to provide accurate and reliable EN 71-3 testing services.
As toy safety regulations continue to evolve, EN 71-3 testing remains an essential component of CE marking, product safety assessment, and access to the European market.
