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.
