Internal Combustion Engines--Piston Rings--Inspection Measuring Principles(Cancelled Jun 2008)
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.
