标准范围

ISO 6621-5:20 05规定了活塞环的质量方面，这些方面可以定义，但通常在图纸规范中找不到。它涵盖以下内容:灰铸铁或钢制单件活塞环；由铸铁件和弹簧部件组成的多片式活塞环（控油环）；钢制单件式和多件式控油环，即带弹簧膨胀器部件的带钢部件或钢段（钢轨）形式的控油环。

ISO 6621-5:2005 specifies those quality aspects of piston rings that are capable of definition but not normally found on a drawing specification.It covers the following:

• single-piece piston rings of grey cast iron or steel;
• multi-piece piston rings (oil control rings) consisting of cast iron parts and spring components;
• single-piece and multi-piece oil control rings of steel, i.e. oil control rings in the form of strip steel components or steel segments (rails) with spring expander components.
