Foreword

This revised standard adopts ISO 6788:1997 "Assembly tools for screws and nuts the size of a cross socket wrenches and torque test" (In English).

This standard is based on ISO 6788:1997 re-drafted. Appendix A lists the control of the standard terms and provisions of a standard international Lanbiao.

Taking into account China's national conditions, in the use of ISO 6788:1997, the standard of this made some changes related to technical differences have been incorporated into the body and they are involved in the provision of margin identified by a single vertical line. Given these technical differences and their causes in Appendix B the list for reference.

This standard and ISO 6788:1997 The main differences are as follows.

--- Some of the statements apply to international standards to apply to our standard formulation;

--- Cited the adoption of international standards of national standards and other standards (Chapter 2 of this edition);

--- Increased material requirements (edition 4.1);

--- Surface treatment and surface quality makes provision (Excerpts of 4.4, 4.5);

--- Test Method for the basic size, hardness, surface treatment and surface quality are prescribed (Chapter 5 of this edition);

--- Makes provision for inspection rules (Chapter 6 of this edition);

--- For packaging, labeling, transportation and storage makes provision (Chapter 7 of this edition);

--- Made an adjustment on the part of the content.

This standard replaces GB/T 14765-1993 "Cross handle socket wrench." this standard and GB/T 14765-1993 compared to the main changes are as follows.

--- Basic size was revised (1993 version 3.2, this version 3.2);

--- Increased product marking (edition 3.3);

--- Increased material requirements (edition 4.1);

--- Minimum test torque adjustment has been made (1993 edition Table 2, Table 3 edition);

--- Increasing the product logo (edition 7.1).
