EN 17420 Impurity Level in Secondary Alloys
The European Standard EN 17420 specifies the methods for determining the impurity levels of secondary alloys, particularly focusing on their compliance with quality standards. This standard is crucial for ensuring that recycled metals and alloys meet stringent purity requirements, which are essential for maintaining product integrity and performance.
Secondary alloys, often derived from post-consumer waste streams or scrap metal, play a significant role in the sustainable production of new metallic products. The impurities found within these secondary alloys can significantly affect their usability in manufacturing processes. Accurate measurement and control of these impurities are paramount for industries that rely on recycled materials.
EN 17420 provides methodologies to identify various types of impurities, including non-metals, organic compounds, and other metallic elements that may be present at trace levels. The standard covers a wide range of secondary alloys such as steel, aluminum, copper, nickel, and zinc. It ensures that these materials meet the specified purity limits set forth by relevant international standards like ISO 9001 for quality management systems.
The testing procedures outlined in EN 17420 involve several steps including sample preparation, dissolution of alloy samples, extraction of impurities using appropriate solvents or techniques, and finally, quantification through analytical methods such as atomic absorption spectroscopy (AAS) or inductively coupled plasma mass spectrometry (ICP-MS).
Compliance with EN 17420 is critical for manufacturers who aim to produce high-quality products while adhering to environmental regulations. By ensuring that the impurity levels are within acceptable limits, companies can enhance product reliability and safety, thereby building trust among consumers.
| Sample Preparation | Dissolution Method | Extraction Technique | Quantification Tool |
|---|---|---|---|
| Cleaning and Cutting | HNO₃ / H₂O₂ digestion | Solvent Extraction | AAS/ICP-MS |
Quality managers, compliance officers, R&D engineers, and procurement professionals play key roles in implementing EN 17420. They must ensure that all steps involved in testing are followed rigorously to obtain accurate results. This includes proper handling of samples during preparation, selecting appropriate dissolution methods based on the alloy type, employing effective extraction techniques tailored towards specific impurities detected, and utilizing reliable quantification tools capable of detecting even minute amounts of unwanted elements.
Adherence to EN 17420 helps maintain consistent product quality across different batches of recycled materials. It also supports sustainable practices by promoting the efficient use of waste streams from various industries including automotive manufacturing, electronics recycling, construction, and aerospace sectors.
