Claim:
1. A closure mechanism for an electromagnetically sealed measuring station, the closure mechanism comprising: a door frame comprising a groove around its entire periphery; a door comprising a door rebate around its entire periphery corresponding to said groove, so that the door attached to the door frame can be moved outward from the groove of the door frame perpendicular to a plane of the door in a closed position in the direction away from a test chamber to which the closure mechanism is associated; a special hinge connected to a side wall of the test chamber, the special hinge comprising a hinge plate and a hinge arm, wherein the hinge plate provides a plurality of slots, wherein the hinge arm includes two hinge pins, wherein movement of the hinge pins within the slots provide linear and pivotal movements of the door, and wherein the hinge pins do not detach from the slots; and a seal configured to create an electromagnetic seal between the door and the door frame around an entire periphery of the door when the door is in the closed position; wherein the door is attached to the door frame in such a manner that the door can be moved initially in a linear manner away from the door frame and the test chamber in a direction perpendicular to the plane of the door so that the door rebate moves out of the groove over the entire periphery and can then be pivoted in a rotational movement, wherein an auxiliary frame is connected to the side wall of the test chamber by rotational hinges; wherein the door is built into the auxiliary frame such the movement of the door in the linear manner away from the door frame occurs within the auxiliary frame; and wherein the seal can be stressed or de-stressed over the entire periphery of the door by movement of the door in the linear manner.
