Cleanliness analysis

The Metallography laboratory has a cleanliness room equipped for cleanliness analysis in accordance with VDA 19 / ISO 16232. For particle extraction, a rinsing cabinet and an open facility for extraction on larger parts are available.

The analytical procedure is standardised - the specific characteristics and geometry of the parts are taken into consideration in parts-specific extraction instructions.

Areas of competence:

  • Standardised cleanliness analysis
  • Analysis according to VDA 19 and specific customer standards
  • Database for recording and analysis of all analytical data
  • Development of customer-specific extraction procedures


  • Rinsing cabinet and other extraction facilities
  • Fully-automatic particle counting microscopes (from 5µm particle size)
  • Precision scale (±0.01 mg)
  • REM / EDX for materials analysis
