Mechanical component cleaning test

  • Evaluation of the degree of cleanliness according to ISO 16232 - ISO 4405
  • Evaluation of the degree of cleanliness according to the standards of the Automotive sector (VDA)

The continuous development of quality standards in the Automotive sector requires the use of components with an ever decreasing content of impurities and processing residues. The test involves extraction of the remaining solid particles with a solvent or water-based mixture, filtration on a membrane with controlled porosity and subsequent gravimetric determination. If necessary, it continues with counting the particles and measuring their dimensions (optical microscopy) and chemical characterization using the EDS microprobe (scanning electron microscopy) to distinguish between metallic and non-metallic particles.
