Foreword
This Standard adopts the Japanese industrial standards JIS H3100-2006 Copper and
Copper Alloy Sheets, Plates and Strips and JIS H3110-2006 Phosphor Bronze and
Nickel Silver Sheets, Plates and Strips by modification; adopts the EU standard BS EN
1652:1998 Copper and Copper Alloys - Plate, Sheet, Strip and Circles for General
Purposes by reference.
This Standard serves as a replacement of GB/T 2059-2000 Strips of Copper and
Copper Alloys, GB/T 2067-1980 Tin-zinc-lead-bronze Strips, GB/T 2069-1980
Aluminum-copper-nickel Alloy Strips, GB/T 11089-1989 Leaded Brass Strips for
Special Purpose and GB/T 15714-1995 Brass (H65) Strip for Welded Tube.

1989 and GB/T 15714-1995, the main changes are as follows:
---Four designations (H63, H85, QSn8-0.3 and BZn18-17) are added. In addition,
Designation C2300 in JIS H3100-2006 and Designation CuZn15 in the EN
standard are used to specify the mechanical properties of Designation H85;
Designation C5212 in JIS H3110-2006 is used to specify the mechanical
properties of Designation QSn8-0.3; Designation C7521 in JIS H3110-2006 is
used to specify the chemical composition and mechanical properties of
Designation BZn18-17;
---For pure copper, the extra-hard (T) state is added; the mechanical properties of
the hard (Y) state are accordingly modified;
---The elastic-hard (TY) state is added to H70, H65, H65 and QSn6.5-0.1; JIS
H3100-2006 and JIS H3110-2006 are used to modify the tensile strength values;
---The lower limit of the available thickness of the strip is modified from “0.05 mm”
to “greater than 0.15 mm”; for pure copper and ordinary brass, the upper limit
of the width of strip with a thickness of 0.5 mm ~ 3.0 mm is expanded from
“1,000 mm” to “1,200 mm”;
---The overall dimensions and tolerances shall comply with the stipulations of GB/T
17793;
---The hardness test is modified from “an optional reference item” into “a routine
inspection item”; it is also stipulated that “choose either tensile test or hardness
test, and when there are no special instructions, provide tensile test”;
---The measurable thickness of the tensile test is modified from not less than “0.3
mm” into not less than “0.2 mm and 0.15 mm”; the thickness requirements for
the hardness test are deleted (that is, all specifications may be tested);
