Sand blowing concentration test in the sand and dust test chamber Author：LINPIN Update Time：2025-04-15 Source：LINPIN Sand and Dust Test Chamber (also known as "Dustproof Test Chamber") simulates the destructive effects of natural wind and sand climates on products. It is suitable for testing the dust resistance and IP dust protection rating of communication products, automotive components (such as rearview mirrors, audio systems, electronics, lighting, lamps), outdoor lighting and signaling devices, as well as the sealing performance of product enclosures. Sand and Dust Test Chamber Sand Blowing Concentration in the Sand and Dust Test Chamber For test samples used near ground vehicles, the sand blowing concentration is 1.1 ± 0.25 g/m³. For test samples only affected by natural conditions, the sand blowing concentration is 0.177 g/m³. For test samples used near aircraft (e.g., helicopters) that may take off, taxi, or fly at low altitudes on unpaved surfaces, the sand blowing concentration is 2.2 ± 0.5 g/m³.
