Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard uses the redrafted law revision adopted IEC 60638. 1979 "Traction motor reversing rotation direction evaluation and coding guidelines." This standard and IEC 60638. 1979 technical differences exist, these differences involve the terms of the margin with a single vertical line (︱) into Row marked. This standard and IEC 60638. 1979 technical differences and the reasons given in Appendix A. This standard and IEC 60638. 1979 structural changes as follows, according to GB/T 1.1-2009 requirements, changing the original chapter number. --- The standard adds Chapter 2, "Normative references"; --- The standard Chapter 3, Chapter 4, corresponding to the original; --- The standard Chapter 4, corresponding to the description in Chapter 2; --- The standard Chapter 5 corresponding to the original Chapter 3; --- The standard Chapter 6 - Chapter 14, followed by the corresponding original Chapter 5 - Chapter 13; --- Increase in Appendix A, the original Appendix A to Appendix B.

The standard (Chapter 12) be amended to read "the pole pitch (single or double Times the pole pitch) "; --- IEC 60638. 1979, there is no clear its appendices "spark observed with variable opacity wedge" in nature. Given that Appendix Content is not necessary to perform this standard will be identified as informative appendices. The standard proposed by the People's Republic of China Ministry of Railways.
