Foreword

Instead of the standard YS/T 255-2000 "Cobalt." Compared with YS/T 255-2000, the main changes in this standard are as follows. --- Scope of this standard excluding fire refining preparation of cobalt metal. --- The Chapter 2, "Normative references" content to "normative references." --- Product added Co9995 grades. --- Different grades of impurities adjusted, in particular (in%). Co9998 grades of P from the revised 0.001 0.0005; Co9980 grade of C from the revised 0.005 to 0.007, Mn from the revised 0.005 0.008, Fe from the revised 0.006 0.02, Cu revised from 0.003 to 0.008, As amended by the 0.0005 to 0.001, Pb revised to 0.0007 from the 0.0004, Zn from the revised 0.002 0.003, Cd 0.0003 by the revised 0.0008, P 0.001 from the revised 0.002, Al made Revised 0.002 0.003, Sn 0.0003 from the revised 0.001, Sb 0.0003 from the revised 0.001, Bi by the 0.0003 Amended to 0.0004; Co9965 grades in the As from the revised 0.001 0.002, Zn 0.002 from the revised 0.004, P by the Revised 0.001 0.003, Sb 0.0005 from the revised 0.002, Bi amended by the 0.0003 0.0005. --- Surface Quality clauses canceled electrolytic cobalt plates of different grades of cobalt, cobalt and cobalt ingot ingot classification and physical requirements and other relevant Content. --- Surface Quality clauses "should be cleared electrolytic cobalt plate lugs" to "If the board of other non-cobalt cobalt lug copper, etc., should be cleared Lug. " --- "Other requirements" electrolytic cobalt plate to block supply, revised cobalt products in one piece or small supply, the demand side, such as cobalt products Special requirements, by mutual agreement of supply and demand, and specified in the contract. --- For Batch mode it has been adjusted, based on the original increase of the same brand of product batch. --- Added "sample cobalt block" content. --- Added "test project" section. --- Increase the "transport and storage" section. --- To Chapter 3, "orders (or contract)," content is adjusted to Chapter 7. --- In the "sampling and sample preparation" chapter in the number of the original sample batches revised standard 5% to 2% of cobalt plate sampling point to the original standard 36 points ranks uniform checkerboard revised to 18.00. This standard by the National Standardization Technical Committee of non-ferrous metals and centralized. This standard was drafted. Jinchuan Group Limited. The main drafters of this standard. Feng Yujie, Lin Hsiu-ying, Zhao Xiuhua, Lv Haibo. This standard replaces the standards previously issued as follows. --- GB/T 6517-1986; --- YS/T 255-1994, YS/T 255-2000. Cobalt range 1 This standard specifies requirements for cobalt, inspection rules, test methods, packaging, labeling, transportation, storage and quality certificate.
