Overview
What is component cleanliness testing?
Chem-Tech Laboratories has facility for component cleanliness testing as per ISO 16232, VDA 19 test standards. Contamination removal from components used in automotive, aerospace, hydraulics and production systems is becoming increasingly important. As suppliers, producers and end users look for better reliability of components and products.

Testing scope
Cleanliness Testing Process
The component cleanliness testing service primarily uses a flushing/pressure rinse method for the removal of contamination from components, hoses, pipes, injectors, pumps, valves, radiators, engine blocks, cylinder heads, cranksahfts and manifolds. The flushing liquid is drawn through a membrane filter and analysed with a Leica microscope to count particles and weighed to give a gravimetric weight in mg. The microscope analysis identifies the quantity of particles in different size classes including longest particle and fibres according to the applicable test standards applied. Results are recorded and sent to the customer in a report as per the template below. The microscope system can categorise particles into reflective and non-reflective to give an indication on the ratio of metallic and non-metallic particles.
Technical review
Common material and compliance considerations
Material identification
The product construction and material groups must be identified so that preparation and analytical scope remain representative.
Restricted-substance scope
Only substances covered by the confirmed requirement and agreed analytical scope are evaluated.
Screening and confirmatory analysis
Screening and quantitative methods serve different purposes and are selected according to the material and reporting requirement.
Compliance interpretation
A compliance conclusion requires the applicable requirement, reporting unit and decision limit to be confirmed.
Before dispatch
Sample-submission guidance
- Use a clean, secure and appropriately labelled container.
- Provide the sample identity, fluid grade and equipment or system details where applicable.
- Share operating hours, maintenance history, the suspected problem and required specification where available.
- Contact Chem-Tech before dispatch so the laboratory can confirm the sample quantity, container and selected testing scope.
Technical output
Reporting and interpretation
The report records results and methods for the agreed scope. Customer-supplied limits or specifications can be considered when provided before testing.
Results should be reviewed with equipment history, operating conditions and previous data; a laboratory result alone does not guarantee a root-cause diagnosis or remaining service life.
