Sand and Dust Test
- Test summary/features
-
Sand and dust testing is used during device development, testing and evaluation to check reliability relative to atmospheric effects from dry sand and dust (fine sand).
Sand and dust tests simulate the effect of particles of sharp-cornered sand and dust (fine sand) of up to 150 microns in size. The particles enter cracks, crevices, bearings and other connections, causing various types of damage responsible for equipment corrosion and malfunctions.

-
Testing can be performed with reference to MIL,NDS,RTCA, and so on.

- Sand and Dust Test System (installed at Kobe Test Center)
Air containing sand and dust is circulated in a wind tunnel, flowing from the top to the bottom of the test area.
The san and dust therefore form a laminar flow from above the test sample and are blown against it, so the test plan needs to specify the test sample placement direction.
The test area measures 600 x 600 x 600 mm (W x H x D). The test sample surface area needs to be no more than 30 to 50% of the floor surface area to ensure there is a path for the air flow.
