Specifies the essential dimensional features of N-, NM-, E- and EM-scraper piston ring types. Dimension tables 7 and 8 offer the choice of two radial wall thicknesses: "regular" (table 7) and "D/22" (table 8). The requirements apply to scraper rings for reciprocating internal combustion piston engines, up to and including 200 mm diameter. May be used for piston rings for compressors working under similar conditions.
