Foreword
The modification of this Standard adopts ASTM B 16/B 16M-2005 "Standard
Specification for Free-Cutting Brass Rod, Bar and Shapes for Use in Screw Machines"
and ASTM B 301/B 301M-2008 "Standard Specification for Free-Cutting Copper Rod,
Bar, Wire, and Shapes". The degree of consistency with ASTM B 16/B 16M-2005 and
ASTM B 301/B 301M-2008 is modified.
The main differences between this Standard and US ASTM B 16/B 16M-2005 and
ASTM B 301/B 301M-2008 are as follows.
- This Standard has 24 more designations than the US standards. HPb57-4, HPb58-
2, HPb58-3, HPb59-1, HPb59-2, HPb59-3, HPb60-2, HPb60-3, HPb63-3,
HBi59-1, HBi60-1.3, HBi60-2, HMg60-1, HSi75-3, HSi80-3, HSb60-0.9,
HSb61-0.8-0.5, HBi60-0.5-0.01, HBi60-0.8-0.01, HBi60-1.1-0.01, QPb1,
QTe0.3, QTe0.5-0.008, QSn4-4-4.Corresponding technical requirements for
these designations are added.
- This Standard does not include the designations C14510 and C14520 that are in
the American standards.
- Compared with the US standards, it adds internal quality, torsion, ultrasonic flaw
detection, residual stress, dezincification corrosion resistance, grain size, cutting
requirements and corresponding inspection method regulations in this Standard.
- This Standard does not include the requirements for resistivity and conductivity as
well as corresponding test method regulations that are in the American standards.
- This Standard does not cover the O60 condition of rods and bars that is in the
American Standard.
This Standard was proposed by China Nonferrous Metals Industry Association.
This Standard shall be under the jurisdiction of National Technical Committee on Non-
ferrous Metals of Standardization Administration of China (SAC/TC 243).
