- Use GB/T 2900.74 that modifies IEC 60050-131 to replace IEC 60050-131 (see Clause 3);

- Use GB/T 2900.83 that identically adopts IEC 60050-151 to replace IEC 60050-151 (see Clause 3);

- Use GB/T 9637 that not identically adopts IEC 60050-211 to replace IEC 60050-211 (see Clause 3);

- Use GB 10068 that identically adopts IEC 60034-14 to replace IEC 60034-14 (see 8.5);

- Use GB 10069.3 that identically adopts IEC 60034-9 to replace IEC 60034-9 and move it into the Bibliography, because Annex C of this document is cited as an informative appendix (see C.8);

- Use GB/T 11021 that identically adopts IEC 60085 to replace IEC 60085 (see 8.1.5);

- Add GB/T 22715 as a reference document (see 9.4.3);

- Delete IEC 62498-1, because it is not directly cited in the text (see Clause 2 and Clause 4 of IEC 60349-4:2010).

- Modify the requirements for altitude to meet the altitude requirements for traction equipment in China (see Clause 4 of this document, Clause 4 of IEC 60349-4:2010);

- Add nameplates to increase important parameters (see 6.1 of this document, 6.1 of IEC 60349-4:2010);

- Delete the additional temperature rise test of the converter power supply in the simplified type inspection, so as to improve the inspection requirements (see 7.3.2 of IEC 60349-4:2010);

- Add assessment test of anti-demagnetization ability to improve the reliability of the permanent magnet motor (see 8.2);

- Modify the loss tolerance requirements so as to be consistent with the loss tolerance of GB/T 25123.2 (see 8.3.2 of this document, 8.2.2 of IEC 60349-4:2010);

- Modify "9.4 Withstanding voltage test" and change it to "9.4 Insulation test". Add "9.4.1 Insulation resistance measurement of stator windings" and "9.4.3 Impulse withstand voltage level of stator coil" to improve product quality (see 9.4 of this document, 9.4 of IEC 60349-4:2010). This Part also makes the following editorial changes.

- Add Note 4 of 5.1 to comply with the provisions of GB/T 1.1-2009;

- Modify the title of 8.7 (7.3 of IEC 60349-4:2010) "Simplified type inspection" to "Additional temperature rise test";

- Modify the citation error in C.1.2;

- Adjust the figure sequence in Annex C;

- Modify the typesetting of Annex E and change it to a table to conform to Chinese habits;

- Add informative Annex F to explain structural adjustments;

- Modify the Bibliography.
