People's Republic of China Nonferrous Metals Industry Standard
Replacing YS/T 450-2002
Refrigerator with high cleanliness brass
Issued on. 2013-04-25
2013-09-01 implementation
Ministry of Industry and Information Technology of the People's Republic of China released
Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
Instead of the standard YS/T 450-2002 "refrigerator with high cleanliness brass." Compared with this standard YS/T 450-2002, the main changes are as follows.
--- Increase the size tolerance requirements;
--- Mechanical properties to add a "proof strength" requirement;
--- Cleanliness of "total impurities" and "water" increases the requirements;
--- Appendix A to add a "solvent injection amount";
--- Appendix C increased the recommended types of extraction agent.
This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized.
This standard is drafted by. Golden Dragon Precise Copper Tube Group Co., Ltd., Zhejiang Hailiang Co., Ltd., the color Obote Cu-Al
Co., Ltd.
The main drafters of this standard. Li Changjie, He Fuliang, Liang Qiming, Zhou Yongli, Wang Zhao, Yan Jiang industry, Li Jianping, Liu, Zhang Xijun, Wang Xiangdong,
Liu on behalf of the star.
This standard replaces the standards previously issued as follows.
--- YS/T 450-2002.
