J1589_199001 INTERNAL COMBUSTION ENGINES - PISTON RINGS - INSPECTION MEASURING PRINCIPLES

Differences, where they exist, are shown in Appendix A.

This document 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 internal combustion engines.

These inspection measuring principles may also be used for piston rings for compressors working under analogous conditions.
