ISO 11841的这一部分定义了道路车辆和通用内燃机（如船用发动机、固定式发动机）中使用的过滤器和过滤器组件特性的术语。 ISO 11841的目的是标准化定义，促进其理解，并为统一翻译成外语奠定基础。 还建议在建立其他技术文件时使用本国际标准。

This part of ISO 11841 defines terms for the characteristics of filters and filter components used in road vehicles and internal combustion engines for general use (e.g. marine engines, stationary engines). The purpose of ISO 11841 is to standardize definitions, to facilitate their understanding, and to create the basis of a uniform translation into foreign languages. It is also recommended that this International Standard be used when establishing other technical documents.
