ASTM E120 Platinum Group Elements in Scrap Alloys
The ASTM E120 standard is a critical tool used to detect the presence of platinum group elements (PGEs) in scrap alloys. This testing method is essential for ensuring that recycled materials meet high-quality standards, which are vital for industries like automotive, electronics, and jewelry manufacturing.
The process involves the following steps: Firstly, the scrap alloy samples must be prepared according to ASTM E120 guidelines. This preparation includes cleaning the specimens thoroughly to remove any contaminants or residues that could skew results. Next, the samples undergo a series of chemical treatments designed to release PGEs into a form suitable for analysis.
The instrumentation used in this testing is highly sophisticated and typically involves atomic absorption spectroscopy (AAS) or inductively coupled plasma mass spectrometry (ICP-MS). These instruments are chosen for their sensitivity and accuracy, which are crucial when detecting minute quantities of PGEs. The results obtained from these analyses provide a quantitative measure of the platinum group elements present.
The ASTM E120 method is particularly important because it helps in assessing the purity and composition of scrap alloys. This information is critical for industries that rely on high-quality recycled materials to ensure product performance and reliability. By adhering to this standard, manufacturers can minimize risks associated with using inferior or contaminated scrap.
The acceptance criteria for ASTM E120 are stringent, ensuring that only samples meeting specific purity levels are deemed suitable for recycling into new products. This ensures a consistent quality of recycled materials across various industries.
