Description / Abstract:
There is no ISO standard equivalent to this SAE Standard.
This SAE standard identifies and defines the most commonly used
terms for piston ring-groove characteristics, 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 combustion engines 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 °C (68 °F).
Tolerances specified in this document represent practical
functional limits and do not imply process capabilities.
