Description / Abstract:
Differences, where they exist, are shown in Appendix A.
This SAE Standard defines the measuring principles to be used
for measuring piston rings. It applies to piston rings up to and
including 200 mm diameter for reciprocating combustion engines.
These inspection measuring principles may also be used for
piston rings for compressors working under analogous
conditions.
Rationale—
SAE J1589 is being discontinued because the content of this
standard is also contained in ISO 6621-2. 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.
