BS ISO 6622-2:2013 pdf free.Internal combustion engines一Piston rings
This part of ISO 6622 specifies the essential dimensional features of rectangular rings made of steel,types R, B, BA, and M having nominal diameters from 30 mm up to and including 160 mm, used in reciprocating internal combustion piston engines for road vehicles and other applications.
The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.Not applicable.
The rectangular ring types are specified in Tables 1 to 5 and Figures 1 to 6. Their common features and the dimensions of those features are specified in Tables 6 to 11 and Figures 7 to 22. Tables 12 and 13 give the force factors for the different ring types, while Table 13 gives the dimensions and forces of the
rectangular rings.
Figure 1 shows the general features of piston ring type R.See Table 13 for dimensions and forces.
EXAMPLE Designation of a piston ring complying with the requirements of this part of ISO 6622 (i.e.ISO 6622-2) being a steel, rectangular ring with a straight-faced peripheral surface (R), of nominal diameter d1 = 60 mm (60), of nominal ring width h1 = 1,2 mm (1,2), made of CrSi alloyed steel, subclass 62 (MC62), and with a chromium-plated peripheral surface of a minimum thickness 0,1 mm (CR2]. Parameters in parenthesis are used in the ISO ring designation: Piston ring ISO 6622-2 R- 60 x 1,2. MC62/CR2
See Table 13 for dimensions and forces.
