Foreword

This revised standard adopts ISO 9657:2004 "folder twist Telecommunications Pliers and nippers - General technical requirements" (in English) and ISO 9656:2004 "Telecommunications clamp Pliers and nippers twist test" (in English).

This standard is based on ISO 9657. redraft 2004.2004 and ISO 9656. Information Appendix A lists the provisions of this national standard Standard Terms and international control list.

Taking into account China's national conditions, in the use of ISO 9657:2004 and ISO 9656:2004, the standard of this made some changes to the relevant technical Differences have been incorporated into the text, and they are involved in terms of the margin of a single vertical line identification. And given in Appendix B ISO 9657:2004 and ISO 9656:2004 and the list of technical differences in the reasons for reference.

This standard and ISO 9657:2004 and ISO 9656:2004 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 (this edition 3.1);

--- Surface treatment and surface quality makes provision (Excerpts of 3.2, 3.3);

--- Cutting pliers cutting edge of telecommunications regulations made slit (Excerpts 3.5);

--- Increasing the clamp shaft hardness (this version 3.7.4);

--- On the shape and size, surface treatment and surface quality, testing methods slit edge makes provision (Chapter 4 of this edition);

--- Makes provision for inspection rules (Chapter 5 of this edition);

--- For packaging, labeling, transportation and storage makes provision (Chapter 6 of this edition);

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

This standard replaces GB/T 15730-1995 "folder twist Telecommunications Pliers and nippers - General technical requirements." this standard and GB/T 15730-1995 compared to the main changes are as follows.

--- Increased material requirements (this edition 3.1);

--- Increased telecommunications clamp shape and size requirements (this edition 3.4);

--- Adjust the clamp jaws telecommunications folder twist top slot requirements (1995 version 3.2.2, this version is 3.5);
