This standard is drafted in accordance with the rules given in GB/T 1.1-2009.

This standard uses the translation method equivalent to ISO 5415.:2007 "with 7.24 outer cone and with the internal thread of the Mo's inner cone set".

And the normative reference in this standard international documents are consistent with the relationship between China's documents are as follows.

Self - clamping cones for machine tools and tool holders (ISO 296.:1991, eqv); GB/T 1443-1996;

--- GB/T 3837-2001 7.24 Manual tool changer cone (ISO 297. 1988, eqv);

GB/T 1804-2000 General tolerances Tolerances of linear and angular dimensions not tolerated (ISO 2768-1. 1989, eqv).

This standard has been modified in accordance with ISO 5415.:2007 as follows.

--- simplifies the standard name;

Figure 1, Figure 2 in accordance with the Chinese cartographic standards on the marked symbols were edited and modified;

--- mark, with our standard number instead of international standard number.
