Since the cleanliness of the components as a quality mark is gaining more importance, it its more common to see the (CCC = component cleanliness code) in the drawings, therewith it also appears quantified, the measurement of this value plays an increasingly important role.

There are specially designed procedures for this purpose and standards have been developed which create reproducible, cost-effective, fast and reliable results.
The performed residual contamination analyses in our facility meet the standards VDA 19 and ISO 16232. Among our customers we have some of the most prestigious automotive suppliers.


The facility was created and qualified in the Year 2006 as the result of the collaboration between a service provider and a major automotive supplier.
