The VT Shed emissions test chambers are for determining evaporation on motor vehicles in accordance with EPA, CARB and EU regulations. One main feature of this test system is volume compensation with the use of a tedlar bag or moveable ceiling enabling temperature profiles to be performed with a hermetically sealed chamber without a differential pressure to enable ambient values.
In addition to exhaust emissions caused by traffic, hydrocarbon vapors are also emitted when refuelling tank systems and by the vehicle itself. Due to the globalization of the automobile industry, the strict regulations of the American Environmental Protection Authorities EPA and CARB have found world-wide recognition in the specifications defining the requirements of environmental simulation technology. The SHED chambers of Weiss Technik which can be temperature conditioned comply with these requirements. Many leading automobile manufacturers and renowned suppliers repeatedly choose Weiss environmental simulation technology for very good reasons. Not least because Weiss Technik is one of the leading manufacturers of testing systems world-wide.
