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 of Standardization Documents"

drafted:

This document replaces GB/T 10892-2005 "Stationary Air Compressor Safety Rules and Operating Regulations", and GB/T 10892-

Compared with:2005, except for structural adjustment and editorial changes, the main technical changes are as follows:

--- Adjusted terms and definitions (see Chapter 3, Chapter 4 of the:2005 edition);

--- Supplementary situations that are likely to cause personal injury (see 6:4, 6:4 of the:2005 edition);

--- Changed the noise health requirements (see 6:5, 6:5 of the:2005 edition);

--- Simplified the requirements for the content of the nameplate (see 7:1, 7:1 of the:2005 edition);

--- Changed the prerequisite requirements for the exhaust temperature limit of the fuel injection rotary machine (see 12:1, 12:1 of the:2005 edition);

--- Changed the temperature requirements for exhaust over-temperature protection (see 12:2, 12:2 of the:2005 edition);

--- Supplement the requirements for inhaled air quality (see 15:2, 15:2 of the:2005 edition);

--- Refine the installation position of the pressure instrument (see 17:1, 17:1 of the:2005 edition);

--- Changed the pressure setting requirements of the pressure relief device (see 20:1, 20:5, 20:6, 20:8, 21:1, 20:1, 20:5, 20:1, 20:5,:2005 edition)

20:6, 20:8, 21:1);

--- Changed the requirements for resetting the pressure relief device (see 24:16, 24:16 of the:2005 edition);

--- Increased lubricating oil classification and typical application requirements (see E:4:2):
