Sand and Dust Considerations in the Design of Military Equipment
Abstract
Sand and dust definitions found in military references show little uniformity and, in some cases, little logic. Based on a review of pertinent literature, it is reasonable to define dust as particulate matter smaller than 74 micrometers and to define sand as particles in the size range between 74 and 1,000 micrometers. Of the two sizes of particles, dust has by far the greater potential for damaging most materiel. Because of the wide range of possible effects of dust, it concluded that three different concentration categories can be considered in materiel design. Military items likely to be used in remote areas and not in association with common military activities may be designed for concentrations of only 5 mg/cu ft; items in common military usage should be designed to meet concentrations up to 30 mg/cu ft; and items likely to be used near aircraft, particularly helicopters, should be designed for concentrations of about 60 mg/cu ft.
