Foreword

Chapter 3 of this standard are recommended, the rest are mandatory.

Accordance with the standards GB/T 1.1-2009. Drafting Rules "Standardization Guide Part 1 standard structure and preparation of" given.

This standard replaces GB 5091-1985 "press safety device technical requirements." This standard compared with GB 5091-1985, the main Technical changes are as follows.

--- Increasing the normative references (see Chapter 2);

--- Increased terms and definitions (see Chapter 3);

--- Increased requirements for interlocking guard (see Chapter 7);

--- Modify the requirements for fixed guards (see Chapter 5, see the 1985 version of Chapter 2);

--- Modify the requirements movable guards (see Chapter 6, see Chapter 3 of the 1985 edition);

--- Changed hands manipulation device requirements (see Chapter 8, see the 1985 version of Chapter 4);

--- Modify the photoelectric protection device of claim (see Chapter 9, see Chapter 6 of the 1985 edition);

--- Modify the requirements for induction type safety device (see Chapter 10, see Chapter 7, 1985 edition);

--- Remove the plate over safety devices (see the 1985 edition of Chapter 8);

--- Remove the pusher safety device (see the 1985 edition, Chapter 9);

--- Remove the handle safety device (see the 1985 edition, Chapter 10);

--- Deleted Appendix A (see 1985 edition of Appendix A).

The standard proposed by China Machinery Industry Federation.

This standard by the National Forging Machinery Standardization Technical Committee (SAC/TC220) centralized.
