Internal Combustion Engines - Piston Ring-Grooves

This SAE standard identifies and defines the most commonly used terms for piston ring-goove charactersitics, specifies dimensioning for groove widths, and demonstrates the methodology for calculation of piston groove root diameter. The requirements of this document apply to pistons and rings of reciprocating internal combustione ngines and compressors working under analogous conditions, up to and including 200 mm diameter and 4.5 mm width for compression rings and 8.0 mm width for oil rings. The specifications in this document assume that components are measured at an ambient temperature of 20 degrees C (68 degrees F). Tolerances specified in this document represent a six sigma quality level.
