The blowing sand teat can’be stored and operated under conditions without experiencing degradation of ita performance, effactiveneas, reliability, and maintainability y due to the abraaion (erosion) or clogging effeet of large, sharp-edged particles. I-1 ~. This teat method is divided small-particle prooedure (dust, fine sand) ability of equipment to resist the effects penetrate into cracks, crevices, bearings, is performed to determine whether materiel blowing sand (149 to 850 pm particle size) I-2 ~.
An,airborne sand and dust environment, associated most often with the hot-dry reglona of Earth, exists seasonally in other regions. Naturally occurring sand and dust storms are,an important factor in the deployment of materiel, but w$th the increased mechanization Of Military operationa, these cause leas of a problem than does sand and duet associated with manta activities. Examples of some problems that could occur as a result of exposure of materiel to blowing sand and dust are: . a. Abrasion of surfaces. b. Penetration of seals. c. Erosion of surfaces. d. Degradation of electrical circuits, MSTHOD 510.2 19 Jllly1983 51O.2-1
