The Applied Environmental Effects Division at White Sands Missile Range can now perform MIL-STD-810, Method 510.4, Dust Testing of hazardous materiel at its new dust test facility located 1.5 miles from the main post area. The new facility houses an American Research Dust Chamber which has a test volume of 4´ H x 4´ W x 4´ D (see left photo). The chamber air temperature and relative humidity are controllable between 60-160°F and 5-30% RH. Dust concentrations up to 10.6 g/m3 ± 7 g/m3 can be provided at air velocities ranging from 5 - 29 m/s. An on-site data acquisition system is available to record temperature, humidity, velocity, and dust concentration parameters throughout the test period.
