This Technical Report specifies the essential dimensional features of R-, B- and M-rectangular piston ring types with narrow ring width.

Dimension Table 8 and Table 9 allow for the use of cast iron (Table 8) or steel (Table 9). Since the modulus of elasticity of steel rings is higher than that of cast iron rings, the fluctuation in the surface pressure will become greater if the free gap is set as the reference for forces. Therefore forces are set using the surface pressure as the reference, in order to minimize the effect of the fluctuation.

The requirements of this Technical Report apply to rectangular piston rings of reciprocating internal combustion piston engines, up to and including 90 mm diameter for cast iron rings and up to and including 100 mm diameter for steel. It may also be used for piston rings of compressors working under similar conditions.
