Chemical safety according to EN 71-3<\/h2><\/div>

EN 71-3<\/strong> defines migration limits for potentially hazardous chemicals from materials that may come into contact with children. In recent years, it has also become a reference for those working with polymeric materials and recycled solutions, because it allows them to clearly demonstrate that the product meets strict chemical safety criteria. Applied to recycled SBR rubber, the standard offers an additional level of reliability, combining a focus on sustainability with scientific verification of substances that can actually migrate from the material. An approach that meets the needs of designers, industry professionals and managers of sensitive environments who are increasingly focused on quality and transparency.<\/p>\n

What is EN 71-3 and why was it introduced?<\/strong><\/h2>\n

EN 71-3<\/strong> is a European standard developed by the CEN – European Committee for Standardization<\/em><\/a>, designed to assess the amount of chemical elements that can migrate from a material when it is brought into contact with a child.
The requirement stems from the realization that some materials could release heavy metals or other substances under real-world conditions of use, such as saliva, sweat or moisture.<\/p>\n

The standard does not evaluate the total content of a substance, but only what can actually migrate<\/strong>, as outlined by the European Commission – Chemical Requirements for Toy Safety.<\/em><\/a>which considers EN 71-3 to be one of the most important references for ensuring the safety of materials intended for children.<\/p>\n

The test focuses on the migration of specific metals and potentially toxic elements, including:<\/p>\n
