Instead of the standard YS/T 264-1994 "high-purity indium." This standard YS/T 264-1994 compared to the main changes are as follows. --- Expanding the scope of high-purity indium; --- Remove the range to 99.999% high-purity indium as raw material, electrolytic refining process to obtain high purity of 99.9999% indium; --- The In-05 grades of high-purity indium chemical composition of Sn content increased from 1.5 × 10-6 to now 1.0 × 10-6; --- Increasing the calculation method of high-purity indium content, ingot weight requirements and ordering contents of a contract; --- The sampling methods into production sample of sampling and sample preparation and sample Arbitration sampling and sample preparation; --- Revised test methods and test results to determine deleted Appendix A. This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized. This standard is drafted by. Nanjing Germanium Technology Co., Ltd. The main drafters. Zhang Liping, Li Guohui. This standard replaces the standards previously issued as follows. --- YS/T 264-1994. High-purity indium1 ScopeThis standard specifies the requirements for high-purity indium, test methods, inspection rules and signs, packaging, transportation, storage, quality certificate and contract (or Orders) content. This standard applies to industrial crude indium as raw material, raw material processing and electrolytic refining process to obtain high purity indium. Products for the production of compound Semiconductor, high-purity alloys, advanced bearing material and semiconductor doping agents.2 Normative referencesThe following documents for the application of this document is essential.
