Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents" Drafting:

This document is modified to adopt ISO 22688:2020 "Quality requirements for brazing of brazed metal materials":

This document has the following structural adjustments compared to ISO 22688:2020:

--- Appendix B corresponds to Appendix C in ISO 22688:2020;

--- Appendix C corresponds to Appendix D in ISO 22688:2020;

--- Appendix D corresponds to Appendix B in ISO 22688:2020:

The technical differences between this document and ISO 22688:2020 and their reasons are as follows:

--- ISO 13585 (see Chapter 3, 6:4:2) is replaced by the normative reference GB/T 41113 to apply my country's technical conditions;

--- Added the term and definition of "brazing welder" (see 3.3) to facilitate the application of this document;

--- Added applicable brazing methods: other brazing (see Chapter 4);

--- Deleted "These quality requirements only refer to those aspects of product quality that are affected by the brazing method and are not limited to the type of product:" System" (see Chapter 4 of ISO 22688:2020), which is repeated in the context;

--- ISO 9712 (see 6.5:2, 7:5:2) is replaced by the normative reference GB/T 9445 to apply my country's technical conditions;

The following editorial changes were made to this document:

--- In order to meet the requirements of my country's standard writing, the name of the standard is changed to "Quality Requirements for Brazing of Metal Materials";

--- Appendix D adds 23 domestic and international standards such as GB/T 13679 and ISO 18496;

--- One foreign standard was updated in Appendix D: AS/NZS1167-1 was changed to AS/NZSISO 17672:
