This application is used for evaluation of particulate contamination on inner and outer surfaces of engine components originating from the production process and environmental conditions.

The degree of surface contamination with residual dirt particles is directly linked to the function and lifetime of the engine components. Component cleanliness testing helps reducing engine failures and start-up breakdowns and improves the product quality.

The inspection is an indirect test method that requires a sampling step in which a test lot of the pre-cleaned component is taken and cleaned under defined conditions once more again. The resulting extraction fluid is filtered by a laboratory process and the residual dirt particles are collected on a filter membrane.

The particle distribution is analyzed in terms of size and type, and are expressed in cleanliness classes (level).

Relevant industrial sectors: automotive industry, automotive supplier chain, service labs, facilities for testing and verification, as well as aviation and space industry.
