Technical cleanliness analysis.

In the automotive sector, technical cleanliness is a key measure of quality. In order to meet customer requirements on technical cleanliness, we have integrated appropriate cleaning processes into our production process. A residual dirt analysis in a clean room environment to control the cleaning step completes our production process.

Thus, we meet the demands of our customers and comply with the promised quality standards.

Identification & Preparation

  • In conjunction with our client, we identify the testing methods with the underlying norms and generate the test specification

  • First, we are using a flushing/pressure rinse method for the removal of contamination from pipes, injectors, pumps, valves, etc

Analytical process

  • Weighing of the filter membrane before filtration

  • Extraction of residual contamination by flushing

  • Filtration of polluted irrigation fluid by vacuum filtration unit

  • Drying of the filter membrane in the drying oven

  • Gravimetry: The residual dirt quantity of the test object is determined by the mass increase of the analysis filter by means of differential weighing

  • Morphological: Microscopy – Determination of number and size of detected particles

Review & Documentation

  • The results are documented in a test protocol

  • The analysis reports can be added directly into your own process documentation
