RAIN TEST chamber This one-piece chamber meets the requirements of the MIL-STD-810F standard (Method 506.4) which defines laboratory tests intended to certify materials of military use, as well as civilian, against environmental damages due to water. Within the scope of watertightness tests described in the standard, the chamber reproduces conditions of rain with wind up to 18 m/s according to the Procedure I, as well as conditions of rain and calm air according to the Procedure III (the Procedure II being not applied as it is only for very large volumes). To realize these procedures, different functioning modes are proposed in manual mode or are programmed inside profiles of the software SPIRALE 3 reachable from the touch screen. In complement to these different functioning modes, an electrical plate is embedded to power various accessories while spinning at 360°. The demineralised water used for spraying is refrigerated and recycled thanks to a retention tank with automatized fillings and drainings.
