Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 8012-2000 "casting tin-lead solder." This standard compared with GB/T 8012-2000, the main technical content
Changes are as follows.
--- Grade 40 by the reduced 37. A class adds two grades codenamed 15A, 5A's. Class B Delete codenamed 35B, 30B,
25B, 20B of the four grades. Containing silver solder delete codenamed 63Ag, 60Ag, 50Ag of three grades, increase codenamed
Ag1.5, Ag2.5 the two grades;
--- Chemical composition partly modified. Code 63AA of impurity elements in bismuth by the ≤0.005% revised to ≤0.008%;
A class codenamed 63A, 60A, 55A, 50A, solder containing silver solder and phosphorus content of bismuth by the modification of ≤ ≤0.01%
0.020%, codenamed Ag2 containing silver solder silver content from 1% to 4% (specific content agreed by both parties) is amended as
1.80% - 2.20%;
--- Delete the original standard "in addition to Sb, Bi, Cu, impurity is not greater than the sum of 0.08%" requirement;
--- The requirement to remove physical properties;
--- Increased production sampling requirements of the product;
--- Deleted "Article weight, 250 ± 25g" provisions.
The standard reference used by the US ASTMB32-2008 "solder metal standards", the international standard ISO 9453-2006 "solder
Alloy chemical composition and shape "and the Japanese standard JISZ3282-2006" solder chemical composition and shape. " Various grades of impurities
Limited are stricter than the corresponding grades above standard limits of impurities. Reference to the physical properties of cast tin-lead solder in Appendix A, and
ASTMB32-2008 grades contrast Appendix B.
This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized.
This standard is drafted by. Yunnan Tin Group Co., Ltd.
Participated in the drafting of this standard. Guangxi China Tin Group Co., Ltd. Yunnan Tin tin timber.
The main drafters of this standard. Baijia Jiang, soup Lan, Li Zhihong, Tan Zuo Ming, Liu rights, Tan Yong, Chen Yun, Zhao Junfeng.
This standard replaces the standards previously issued as follows.

Ingot weight/kg 25 ± 3 10 ± 1 5 ± 0.5
Article weight/g 1000 ± 100 500 ± 50 -
3.4.2 When the shape and quality of the cast tin-lead solder with special requirements, agreed upon by both parties.
Test Method 4
Arbitration chemical composition analysis 4.1 casting tin-lead solder according to the provisions of GB/T 10574 performed.
4.2 casting tin-lead solder as required elements other than those specified in Table 1 is detected by the supply and demand sides determined in consultation analysis.
