Scope and Field of Application—Differences, where they exist, are shown in Appendix A.

This SAE Standard specifies the essential dimensional features of R, B, and M rectangular piston ring types.

Dimensional Tables 8 and 9 offer the choice of two radial wall thicknesses:

Radial wall thickness "regular" (Table 8)

Radial wall thickness "D/22" (Table 9)

The requirements of this document apply to rectangular rings for reciprocating internal combustion piston engines up to and including 200 mm diameter. They may also be used for piston rings of compressors working under similar conditions.

Rationale—SAE J1997 is being discontinued because the content of this standard is also contained in ISO 6622-1. Therefore, to eliminate duplication and confusion in coordinating the standards between ISO and SAE, this document will be discontinued. The SAE Piston and Ring Standards Committee will now continue to support ISO in updating the standards as appropriate.
