This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents".

Drafting.

This document is modified to adopt ISO 22752:2021 "Railway application of side windows for locomotive and rolling stock".

This document has undergone significant structural adjustments compared to ISO 22752:2021.A table comparing the structural numbering changes between the two documents is provided.

See Appendix A.

This document differs significantly from ISO 22752:2021.The relevant clauses are indicated in vertical margins.

Single lines (|) are marked. A summary of these technical differences and their reasons can be found in Appendix B.

The following editorial changes have been made to this document.

---To align with existing standards, the standard name has been changed to "Side Windows of Rail Transit Locomotives and Rolling Stock";

---Sources for terms and definitions have been removed;

---The term "glass materials" has been supplemented with a note to clarify the types of glass materials included (see 3.4);

---The term "tempered glass" has had its note deleted (see 3.5);
