Nuclear weapons tests in Australia known at the time as Christmas Island (not to be confused with Christmas Island in the Indian Ocean) between 1957 and 1958. These were airbursts mostly occurring over water or suspended a few hundred metres above the ground by balloon. In Australia there were three sites. Testing was carried out between 1952 and 1957 and was mostly done at the surface. A few hundred smaller scale tests were conducted at both Emu Field and Maralinga between 1953 and 1963. Two separate atomic test projects occurred at the islands, the first being Operation Hurricane and the second being Operation Mosaic The
Mechanical device test stands Mechanical device test stands A mechanical device test stand is one specific type of test stand. It is a facility used to develop, characterize and test mechanical components. The facility allows for the testing of the component and, it offers measurement of several physical variables associated to the functionality of the component. Such components could be electromechanical, motors or tools. The intended use of the test stand is for compliance testing of predetermined desired values and fatigue testing. A sophisticated mechanical component test stand houses several integrated measurement and control (imc) components, such as sensors, data acquisition devices and actuators
