Sand & Dust Test Chamber – MIL 810F & MIL 810G

The MIL sand & dust chamber is designed specifically to simulate desert environments for the testing of military equipment and devices. Inside the test space the dust is blown as per MIL-STD-810G Method 510.5 Procedure-I with a dust concentration of 10 + 7 g/m3 with air velocity of minimum 1.5 m/s up to 8.9 m/s. While the sand is blown as per MIL-STD-810G Method 510.5 Procedure-II with a sand concentration of 0.18 g/m3 to 2.2 g/m3, with an air velocity of 18-29 m/s.

The sand and dust feeders are automatically controlled based on the dust concentration level set in the controller. The air velocity is controlled using a VFD. The humidity can be set to maintain <30% RH. All these parameters can be programmed using the envicom Graphite colour touchscreen using Siemens SIMATIC controllers.

The 1000 L chamber has temperature range between 23°C to 90°C. The interior of the chamber is built with 304 grade stainless steel treated for erosion resistance and high temperature application to avoid creep failure. The exterior body is made of GI with electrostatic powder coating offering high wear resistance. It’s all systems as well as the sub-systems are shielded to provide protection from sand and dust particles. The test space is fitted with externally controlled turn table to rotate the specimen in any direction which could bear a weight up to 150 kg. The viewing window in test space is provided with wipers for user to view the specimen under testing.
