Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
The standard instead of GB/T 5587-2003 "silver-based electrical contact basic shape, size, symbols and labeling."
This standard and GB/T 5587-2003 compared to the main changes are as follows.
--- Added the contents of the three composite rivet type electrical contacts (see 3.2.2);
--- modified flat and spherical rivet-type electrical contact head recommended size (see Table 2);
--- Examples of symbols and annotations for adding silver and fine silver (see Table 5).
This standard is proposed by China Electrical Equipment Industry Association.
This standard is under the jurisdiction of the National Electrotechnical Standardization Technical Committee (SAC/TC228).
