Blowing Sand Dust Test Chamber

Blowing sand dust test chamber is used for evaluating the resistance of a system to dust and sand particles in accordance with MIL-STD-810g standard


The purpose of dust (< 150μm) procedure: This test procedure is performed to assist measure the flexibility of equipage to resist the results of mud that will hinder openings, penetrate into cracks, crevices, bearings, and joints, and to judge the effectiveness of filters.

Sand (150 to 850μm particle size) procedure: The Sand (150 to 850μm particle size) procedure is performed to assist measure the flexibility of equipage to be hold on and operated in processing sand conditions while not degrading performance, effectiveness, responsibility, and maintainability because of abrasion (erosion) or preventive effects of huge, sharp-edged particles.
