This section GB/T 1149 Part 3.
This part identical with ISO 6621-3.2000 "Piston Ring Part 3. Material specifications" (in English).
This section is equivalent translation ISO 6621-3.2000.
For ease of use, this section made the following editorial changes.
--- "ISO 6621 this part" to "this Part";
--- Remove the foreword and introduction of international standards.
This part of ISO 6621-3.2000 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.
This Part replaces GB/T 1149.4-1994 material specifications section "Piston Ring technical requirements" in this section and
GB/T 1149.4-1994 material specifications section compared to the main technical content changes are as follows.
--- Hardness tests according to Vickers hardness test method provides that the value represented by HV30, and Rockwell hardness HRB, HRC reference only;
--- Increasing the level of fine material.
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.

Piston Ring
Part 3. Material specifications
1 Scope
This section GB/T 1149 and by the mechanical properties of the material allowable stress of piston ring materials used are classified.
This section applies to a cylinder diameter of less than or equal to 200mm reciprocating piston internal combustion engine piston rings. Pressure working under similar conditions
Compressor piston ring can also refer to use.
2 Normative references
The following documents contain provisions which, through reference to GB/T 1149 to the present, constitute provisions of this section. For dated reference documents
Member, all subsequent amendments (not including errata content) or revisions do not apply to this section, however, encouraged to reach under this section
Parties to research agreement to use the latest versions of these documents. For undated reference documents, the latest versions apply to this
section.
