本文件规定了道路车辆功能相关部件和系统（清洁度检查）微粒污染测定方法的应用和记录要求。 清洁度检查是技术清洁度评估的基础，例如在以下情况下进行: -初步检查和评估； -检查进出部件；和 -与清洁度相关的制造过程的质量控制或监控（例如清洁、表面处理和装配过程）。 本文件旨在提高测试结果的信息质量和可比性。 它还定义了汽车行业质量链中清洁度规范和清洁度测试结果的标准化表达。 本文件不适用于以下情况: -薄膜污染检测（油脂、油等）； -在测试组件上应用不可量化的颗粒检测方法（例如，目视评估、用干净的布擦拭测试等）；和 -工作液（燃油、机油、冷却液、制动液等）的特性。 本文件未定义特定部件或系统的任何清洁度限值。特定部件或系统所需的清洁度取决于许多高度- 个人因素。清洁度规范仅由不仅了解相关部件，而且了解其内置系统、后期使用条件、技术可行实践以及对制造过程和供应链可能产生的后果的专家来执行。推导极限值的指南见附录H。

This document specifies requirements for applying and documenting methods for determining particulate contamination on functionally-relevant components and systems (cleanliness inspection) of road vehicles. A cleanliness inspection comprises the basis of an assessment of technical cleanliness, which is performed, for example, under the following circumstances: — initial inspection and evaluation; — inspection of incoming and outgoing components; and — quality control or monitoring of manufacturing processes relevant to cleanliness (e.g. cleaning, surface treatment and assembly processes). This document is intended to improve the informative quality and comparability of test results. It also defines the standardized expression of cleanliness specifications and cleanliness test results in the quality chain of the automotive industry. This document does not apply to the following: — detection of filmy contamination (grease, oils, etc.); — application of non-quantifiable particulate detection methods on test components (e.g. visual assessment, wipe test with clean cloth, etc.); and — characterization of operating fluids (fuel, oils, coolants, brake fluid, etc.). This document does not define any cleanliness limit values for specific components or systems. The degree of cleanliness required for a specific component or system is dependent on a number of highly-individual factors. Cleanliness specifications are intended to be undertaken only by specialists who not only know the component concerned but also the system it is built into, the later conditions of use, technically-feasible practices and possible consequences for manufacturing processes and the supply chain. Guidance for deriving limit values can be found in Annex H.
