UNE EN 13657 Leaching of Hazardous Substances in Solid Materials
The UNE EN 13657 standard specifies the methods for determining the leachability of hazardous substances from solid materials. This method is particularly important for ensuring that products intended for use by consumers, especially children or those with a higher likelihood of exposure, do not release harmful substances into their environment.
This testing procedure is crucial in sectors like consumer goods, electronics, and building materials where the safety and environmental impact of products are paramount. Compliance with this standard helps manufacturers meet regulatory requirements, ensuring that their products are safe for use while minimizing potential risks to human health and the environment.
The test involves immersing solid samples in a leaching solution under controlled conditions over a specified period. The extract obtained is then analyzed for its content of various hazardous substances using analytical techniques such as GC-MS (Gas Chromatography-Mass Spectrometry), ICP-MS (Inductively Coupled Plasma Mass Spectrometry), or HPLC (High Performance Liquid Chromatography).
The primary goal of this method is to assess the potential release of hazardous substances from solid materials during their intended use. By following UNE EN 13657, manufacturers can ensure that their products do not pose a risk when they come into contact with water or other media that could facilitate leaching.
The test parameters are critical and must be adhered to strictly for accurate results. The choice of leaching solution, duration of immersion, temperature, and agitation speed all play significant roles in the outcome. Specimen preparation is also a crucial step; it involves selecting appropriate samples, ensuring they represent the product’s composition accurately.
Instrumentation plays a vital role in this testing process. Instruments like GC-MS or ICP-MS are used to analyze the leachate for various hazardous substances. These instruments must be calibrated regularly and operated by trained personnel to ensure accurate results.
Scope and Methodology
| Parameter | Description |
|---|---|
| Leaching Solution | The leaching solution is typically water at a temperature of 50°C, though other solutions may be specified depending on the material. |
| Immersion Duration | The duration can vary from 1 hour to up to 24 hours, depending on the material being tested and the expected release rates. |
| Agitation | Continuous agitation is required during immersion to simulate real-world conditions where materials may be subject to movement or shaking. |
| Sample Preparation | Samples must be representative of the product and free from contamination. They are cut into small, uniform pieces. |
The methodology ensures that all samples undergo identical conditions to minimize variability in results. This standard is widely recognized for its ability to provide consistent and reliable data on leaching behavior, making it a cornerstone of regulatory compliance and product safety.
