Foreword
Chapter 5 of this standard is mandatory, the rest are recommended.
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
Since the implementation of this standard, GA 79-1994 "fire ball performance requirements and test methods" abolished.
This standard compared with GA 79-1994, in addition to editorial changes outside the main technical changes are as follows.
--- To increase the "driving mode" category (see 3.3);
--- Simplifying specifications, according to the relevant standard selected DN (nominal size), and adjust the model designation (see Chapter 4,
1994 edition 3.2);
--- Increasing the length of the structure and the valve connection size requirements (see 5.1.3);
--- Increased ball runner requirements (see 5.1.4);
--- Increased requirements for power-driven ball valve unit (see 5.1.5);
--- Increasing the flow components of the corrosion resistance requirements and test methods (see 5.2,6.2);
--- Increasing the operating handle emergency requirements (see 5.3.2);
--- Modify the index pressure, static pressure sealing performance and service life (see 5.4.1,5.4.2 and 5.5, the 1994 edition of 4.4.1,4.4.2
And 4.5);
--- Remove the valve coating color requirements (see 1994 edition 4.6);
--- Modified valve packing, transport and storage requirements (see 82, 1994 version 7.2.);
--- Increasing the number of samples and test procedure ball description (see Appendix A).
