The RMS Foundation has further expanded its particle analysis capabilities and now also offers technical cleanliness testing according to VDA 19 Part 1 as a service. For this purpose, equipment was procured which makes it possible to carry out so-called cleanliness analyses in accordance with standards. Among other things, the equipment park was expanded with an extraction cabinet from Hydac and a filter analysis system from Jomesa.
The particles are washed off from the component to be examined under defined conditions in the extraction cabinet and then held on an analysis filter.
The filter analysis system serves to automatically count, measure and classify the particles on the filter according to their type (metallic, non-metallic, fibres).
The filter analysis system serves to automatically count, measure and classify the particles on the filter according to their type (metallic, non-metallic, fibres).
If required, the particle load can also be determined gravimetrically using an analytical balance. In order to avoid cross-contamination, the cleanliness analyses are carried out in a clean room ISO 14644-1, class 7. Optionally, it is possible to check the composition of selected particles with existing analysis equipment such as SEM/EDX or FT-IR and thus possibly also determine their exact origin. Technical cleanliness has become a fixed quality factor in the customer-supplier relationship, and no longer only in the automotive industry.
