Foreword
This Standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard replaces GB/T 2059-2008 “Sheet of copper and copper strip”.
Compared with GB/T 2059-2008, the main changes in this Standard are as follows.
- ADD the code name of copper and copper alloys;
- MODIFY the designation and state of alloys;
- ADD 3 designations, i.e. H66, BZn18-18 and BZn18-26, and the corresponding
requirements;
- ADD H08 state to designation QSn8-0.3;
- MODIFY the thickness and width range of some strips;
- MODIFY the mechanical property of some strips;
- DELETE the provisions of Rockwell hardness (HRB);
- MODIFY the “Dimension measurement method” TO “The test method for
dimension of strips is in accordance with the provisions of GB/T 26303.3”;
- ADD the reference to YS/T 482 “Methods for analysis of copper and copper alloys
- The atomic emission spectrometry” and YS/T 483 “Methods for analysis of
copper and copper alloys - X-Ray fluorescence spectrometric (wavelength
dispersive)”;
- MODIFY the tensile test sample number according to the provisions of GB/T
228.1-2010;
- ADD the provision of “The sampling method shall comply with the provisions of
YS/T 668; the sample for mechanical properties and process performance shall
be prepared according to the provisions of YS/T 815”;
- ADD the provisions of the sampling direction of strips for bend test.
