People's Republic of China Nonferrous Metals Industry Standard
Drilling water system components with easy cutting copper alloy ingots
2011-12-20 release
2012-07-01 Implementation
Issued by the Ministry of Industry and Information Technology of the People's Republic of China
Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard refers to ASTMB30-2010 "copper and copper alloy ingot", combined with China's drinking water system parts with easy cutting copper alloy
The actual situation of the ingot. Annex A of this standard is modified using NSF/ANSI61-2007a "Drinking Water System Components - Health
Influence "of soaking water metal precipitation detection method.
In this standard, ZHBi87-1.0-5-0.5, ZHBi86-1.9-5.5-1.0, ZHBi86-1.5-5-0.2, ZHBi86-1.4-4, ZHBi61-
0.9-0.4, ZHSi76-3 grades used in the ASTM B30-2010 in the C89510, C89520, C89530, C89535, C89540,
C87850 alloy composition, compared with ASTMB30-2010, the standard added ZHBi60-0.5-0.6, ZHSi63-0.7, ZHSi75-3,
ZHSi62-0.6, ZHBi62-2-1 four grades. This standard copper ingot soaking water metal precipitation limit of the technical requirements and NSF/ANSI61-
2007a standard is the same, soaked in water precipitation detection method part of the NSF/ANSI61-2007a based on the increase in the copper ingot sample
The preparation method.
This standard is owned by the National Committee for the Standardization of Nonferrous Metals (SAC/TC243).
