Technical cleanliness testing

System: Various

Test environment:

  • Clean room ISO 14644-1 Class 8
  • Laminar Flow ISO 14644-1 Class 5

Test equipment:

  • Extraction cabinet (Hydac CTU 1040)
  • Ultrasonic bath (Bandelin Sonorex Digiplus DL512H)
  • Stainless steel filtration unit (Sartorius)
  • Analytical balance (Mettler XPE 2015, 0.01 mg)

Advanced analyses:

Useful tips:

Suitable samples:
  • Function-relevant components and packaging
  • Liquids, e.g. from abrasion tests
Sample specifications:
  • Sample size < 40 cm
  • According to cleanliness specification
Range/Options:
  • VDA 19 Part 1 Standard analysis, particle detection ≥ 25 μm
  • If required, particles ≥ 10 µm can also be detected microscopically. For the detection of smaller particles down to 0.05 µm, the filters can be examined with a scanning electron microscope.

Application(s)

  • Cleanliness of components and packaging.
  • Particle analysis of test liquids.

Standards

  • VDA 19 Teil 1, Prüfung der Technischen Sauberkeit
  • ISO 16232, Road vehicles - Cleanliness of components and systems
  • Customer specific factory standards, technical cleanliness testing
