EN ISO 6622-1 Internal Combustion Engines - Piston Rings - Part 1: Standard Test for Rectangular Rings Made of Cast Iron

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN ISO 6622-1 testing. EN ISO 6622-1 specifies the basic dimensional characteristics of rectangular rings made of cast iron type R, B, BA and M, with diameters up to and including 200 mm, used in reciprocating internal combustion piston engines. It can also be applied to the rings of compressors operating under similar conditions.

The common properties and size tables presented in this section of EN ISO 6622 create a wide range of variables and when choosing a particular ring type the designer must keep in mind the conditions under which it will be required to operate.

An outward-expanding circular iron spring fits into a piston groove, sealing against the gas or liquid pressure difference between the circumferential and side faces of the ring and the bore and piston groove. The keystone ring is used where ring sticking can be expected. Due to its wedge shape, any radial movement of the ring will change its axial clearance, thus minimizing combustion residue build-up.
