Description / Abstract:
Scope and Field of Application—Differences,
where they exist, are shown in Appendix A.
This SAE Standard specifies the essential dimensional features
of T, TB, TM, K, KB, and KM keystone piston ring types.
The requirements of this document apply to compression rings for
reciprocating internal combustion engines up to and including 200
mm diameter.
Rationale—SAE J2000 is being discontinued
because the content of this standard is also contained in ISO
6624-1. 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.
