Foreword

GB/T 1149 "Piston Ring" for the series of standards, divided into sixteen sections. --- Part 1. General rules; --- Part 2. Terminology; --- Part 3. Material specifications; --- Part 4. Quality requirements; --- Part 5. Test methods; --- Part 6. Cast wiper; --- Part 7. rectangular cast iron ring; --- Part 8. rectangular steel ring; --- Part 9. trapezoidal cast iron ring; --- Part 10. trapezoidal steel ring; --- Part 11. Cast iron wedge ring; --- Part 12. wedge-shaped steel ring; --- Part 13. Oil ring; --- Part 14. Spiral spring supporting oil ring; --- Part 15. Cast iron spiral stays reed thin oil ring; --- Part 16. strip combination oil ring. This is Part 9 GB/T 1149's. This part identical with ISO 6624-1.2001 "Piston Ring Part 1. Ladder Ring" (in English). This section is equivalent translation ISO 6624-1.2001 (in English). For ease of use, this section made the following editorial changes. --- "ISO 6624 this part" to "this Part"; --- Remove the foreword and introduction of international standards. This part of ISO 6624-1.2001 and other international standards adopted by our country who have been adopted as a standard by our standards instead of phase Corresponding to international standards; our country has not been adopted as a standard, still direct use of international standards. This part is the GB/T 14223-1993 "Piston Ring keystone ring and wedge ring" amendments, this section and GB/T 14223-1993 The main difference is. --- GB/T 14223-1993 is equivalent to ISO 6624-1. 1986 and ISO /T R6624-2. 1986, and the Department is divided into equal Using ISO 6624-1.2001. Since the implementation of this portion instead of GB/T 14223-1993 "Piston Ring keystone ring." This part is proposed by China Machinery Industry Federation. This part of the internal combustion engine by the National Standardization Technical Committee (SAC/TC177) centralized. This section was drafted by.
