ST – Dust test chamber

Dust Test Chamber according to Standard SAE J575

The dust is filled in the funnel below the test space. The formation of dust within the test space is effected by compressed air injection through four special nozzles. The dust is blown and swirled in upper test space by intensive air movement.

Features

• According to state-of-the-art manufacture the test cabinets are of a modular design and are ready to be installed
• The whole system is designed to be used under extreme conditions and guarantees reliable functioning and a long service life
• Independent of design and condition of the test specimen a constant dust density is reached due to special high-capacity compressed air nozzles, which leads to reliable test results

Aplication
Dust tests are mainly performed to test functioning of electronic components under extreme environmental conditions. Various standards specify e.g. the test duration and the composition of dust used. The standard SAE J 575 is performed with three to five kilogrammes unburnt Portland cement (according to ASTM C 150-77). Portland cement is especially characterised by its fine grain size. This dust is filled in the funnel below the test space. The formation of dust within the test space is effected by compressed air injection through four special nozzles. The dust is blown and swirled in upper test space by intensive air movement.


The pulse time for this action is 2 to 15 seconds with a brake of 15 minutes between the single impulses.
