an apparatus used in carrying out quality-control and acceptance tests on an object. A test stand has a table or platform with fixtures for rapid mounting and securing of the test object. There are also testing and measuring instruments on the stand, as well as connections for supplying electric power, compressed air, water, steam, oil, and fuel, depending on the object and the program of tests. Stands used in testing heavy assemblies and machines are also equipped with turning and hoisting devices. Readings from the testing and measuring instruments are taken visually or are registered by recorders. In assembly-line and automated production, semiautomatic or automatic test stands are positioned at certain points on the production line. Here, the mounting and removal of test objects, the making of connections, and the recording of readings must all be done within a rigidly specified period of time.
