Foreword

This revised standard adopts the International Standard ISO 3719:1994 "Mechanical vibration - Balancing machines and instruments with graphic symbols" (in English).

This standard and ISO 3719:1994 as compared to, editorial changes as follows.

--- Deleted the ISO foreword, and rewrite the foreword of this standard;

--- Use the "standard" word instead of "this International Standard";

--- Modify the graphic symbols 6-19,6-20 and 7-12 and in this standard renumbered 6-21,6-22 and 7-15;

--- Added "correcting plane angle" graphic symbols, this standard is numbered 6-06;

--- Increased "in correction planes compensation" graphic symbols, in the present standard number 6-20;

--- Increased "in correction planes" graphic symbols, this standard is numbered 7-03;

--- Added "correcting plane angle" graphic symbols, this standard is numbered 7-06;

--- Increased "in the correction plane unbalance" graphic symbols, this standard is numbered 7-09;

--- Fixed the A-18 graphic symbols because the symbol does not match the name selected from the IEC 417 international standard;

--- Remove the A-13, A-15, A-16, A-20, A-24 and A-25 symbol explanation;

--- According to modify the contents of the English text indexing, the addition of graphical symbols for the relevant symbol numbers have been adjusted.

This standard is GB/T 9238-1998 "balancing machines and associated instrumentation graphical symbols" amendments.

This standard replaces GB/T 9238-1998.

This standard compared with GB/T 9238-1998, the main modifications are as follows.

--- According to GB/T 1 series of standards prescribed rewrite this standard;

--- According to the text content modification of Chinese and English indexes.

Appendix A of this standard is a normative appendix, Appendix B is an informative annex.

The standard proposed by China Machinery Industry Federation.

This standard by the National Standardization Technical Committee tester (SAC/TC122) centralized.
