Introduction: GB/T 42516-2023 "Chemical Analysis Method for Platinum Content in High Temperature Shape Memory Alloy - Determination by Thiourea Complex Precipitation Method" is a standard developed by the National Standardization Administration of China. This standard specifies a method for the determination of platinum content in high temperature shape memory alloys using the thiourea complex precipitation method. Platinum is an important element in high temperature shape memory alloys, and its accurate determination is crucial for quality control and material characterization. The thiourea complex precipitation method described in this standard offers a reliable and precise analytical technique for measuring the platinum content in these alloys. The method involves the formation of a thiourea complex with platinum, followed by the precipitation of the complex using a suitable reagent. The resulting precipitate is then collected, dried, and weighed to determine the platinum content. The standard provides detailed instructions on sample preparation, reagent requirements, and analytical procedures to ensure accurate and reproducible results. The implementation of GB/T 42516-2023 will contribute to the standardization and quality assurance of platinum content determination in high temperature shape memory alloys. It will facilitate the development and production of these alloys for various industrial applications, including aerospace, automotive, and medical sectors.
