This International Standard specifies the content of an inspection document that specifies both the cleanliness requirement for the specified hydraulic fluid power component and the inspection method to be used for evaluating its cleanliness level. In addition, guidelines for relevant extraction methods and analysis methods are given.

Determination of what constitutes as an appropriate cleanliness level requirement for any particular component is beyond the scope of this International Standard. ISO12669 provides a method of determining the required cleanliness of a hydraulic system. ISOTR10686 provides a method of relating the required cleanliness of components to the required cleanliness of the hydraulic system.

For the purposes of this International Standard, approved functional liquids are considered to be components.

This International Standard is applicable to the particulate contamination on the wetted surfaces and volumes of any hydraulic fluid power system component. Appearance defects and liquid or gaseous contamination are not covered by this International Standard.

This International Standard does not address safety problems that might arise from hazardous materials, operations, and equipment associated with its use. The user of this International Standard is responsible for establishing appropriate safety and health practices and determining the applicability of regulatory limitations prior to use.
