本SAE标准规定了活塞环的一般特性和单个尺寸标准，这些标准在第2节的文件中有适当规定。本文件还提供了活塞环的编码、命名和标记系统。本文件适用于往复式内燃机直径小于等于200 mm的活塞环的制造。它也适用于在类似条件下工作的压缩机活塞环。

This SAE Standard specifies the general characteristics of piston rings and individual dimensional criteria, which are specified as appropriate in the documents in Section 2.This document also provides a system for coding, designation, and marking of piston rings. This document applies to the manufacture of piston rings up to and including 200 mm diameter for reciprocating internal combustion engines. It also applies to piston rings for compressors working under similar conditions.
