ASTM E1915 Chemical Analysis of Precious Metals Testing
The ASTM E1915 standard is a critical tool for the precise analysis and certification of precious metals, ensuring that products meet stringent purity and composition requirements. This test method is particularly essential in industries such as jewelry manufacturing, electronics, and fine art conservation where even trace amounts of impurities can significantly affect product quality.
The ASTM E1915 standard specifies a procedure for the chemical analysis of precious metals using gravimetric and volumetric methods. It applies to gold, silver, platinum group metals (PGMs), palladium, iridium, osmium, rhodium, ruthenium, and other similar elements that are part of the “precious metals” category.
The test method is designed for materials in a powdered form, which allows for a consistent and repeatable analysis process. This is particularly important given the variability that can occur with precious metal samples due to their varying purity levels. The standard outlines specific procedures for sample preparation, including drying and ashing of the powdered material, followed by dissolution using nitric acid.
The chemical analysis itself involves gravimetric determination of metals in solution or titration methods such as potassium permanganate (KMnO4) for gold and silver, and iodometric titrations for platinum group elements. These methods are chosen for their accuracy and precision, ensuring that even minute quantities of precious metals can be detected.
The ASTM E1915 standard is widely recognized and used globally due to its reliability in providing consistent results across different laboratories. This standardization ensures uniformity in the testing process, which is crucial for maintaining high-quality standards in industries reliant on precious metals.
