Sand- und Staubtest

Sand & Dust Testing at TechnoLab

Sand and dust tests (Blowing Dust / Sand tests) are carried out to assess the effect of dust or sand on various objects. This can cause a whole range of different failure symptoms, including:

The classic tests can be IP protection type tests IP5x and IP6x, which examines the penetration of dust into enclosures.

In sand tests, it is rather the abrasive influences that are investigated. For example, a desert storm or the movement of a vehicle, e.g. a high-speed train in the desert. At wind speeds of up to 100km/h, effects such as the removal of writings on labels, dulling of glass surfaces or the mechanical failure of moving components occur here. Sands are preferably used with grain sizes from 150µm to 850µm.

Explanation of the sand/dust test

Sand/dust testing can cause a whole range of different failure modes, including:

  • Penetration of enclosures or capsules
  • Change of electrical properties (faulty contacting; change of contact resistance; change of creepage resistance).
  • Seizure or restriction of movement of mechanical parts (bearings, axles, shafts, etc.)
  • Wear of the surface (abrasion)
  • Contamination of optical surfaces
  • Contamination of lubricants
  • Clogging of vents, reducers, pipes, filters, openings

Dust tests for the aviation sector are carried out together with an air flow to force the penetration of dust into products. For military equipment, the air speed is up to 9m/s (32km/h). The dust usually consists of talc, silica sand, feldspar and other minerals. Arizona dust, for example, is a combination of several components, China Clay is also sometimes used. The grain sizes are smaller than 150 µm.

Special tests can also be carried out with magnetic dusts or dusts containing fibers. This allows simulations of dusts in tunnels or in mining (coal dust) to be simulated.

Sands with grain sizes from 150µm to 850µm are preferred.
