Sand and dust testing is performed in accordance with MIL-STD-810. The dust chamber can circulate silica powder through a 4´ L x 4´ H x 4´ W test volume. The air velocity can be controlled up to 45 mph. The temperature of the circulating air can be controlled from 70°F to 170 °F. Non-conditioned field sand tests can be performed on hazardous test items at ETA-II using up to 3 portable wind generators.
