This standard replaces GB/T 4310-1984 "vanadium". Compared with GB/T 4310-1984, the main technical differences are as follows. --- increase the normative reference documents; --- increase the definition of margin; --- clear the chemical composition, particle size and appearance of the quality of the test method; --- batch approval in the batch requirements to expand to not more than 20kg; --- updated product packaging requirements; - Added the requirements for the contents of the order (or contract). This standard is proposed by China Nonferrous Metals Industry Association. This standard is owned by the National Committee for the Standardization of Nonferrous Metals (SAC/TC243). The drafting unit. Dalian Rongde Special Materials Co., Ltd., Xi'an Honghai Metal Materials Co., Ltd., Aohanhua Titanium Co., Ltd., Shangluo Amano high-tech materials limited liability company. The main drafters of this standard. Qiao Min, Sun Shiyan, Wang Fuli, Tian Shuming, Zhang Jiangfeng. This standard replaced the previous version of the standard release. --- GB/T 4310-1984. Vanadium 1 Scope This standard specifies the requirements for vanadium, test methods, inspection rules, signs, packaging, transportation, storage and quality certificates and orders (or Same) content. This standard applies to the melting salt electrolysis refining method of vanadium production. This product is used for superconducting materials, fast neutron reactor structural materials and special Alloy additives and so on.2 normative reference documentsThe following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article Pieces. For undated references, the latest edition (including all modifications) applies to this document. YS/T 540 (all parts) vanadium chemical analysis method3 request3.1 Product Classification According to the product impurity content is different, the product is divided into V-1, V-2, V-3 and V-4 four grades. 3.2 Chemical composition The chemical composition (mass fraction) of each grade product shall comply with the provisions of Table 1.
