ABSTRACT:
A method and an apparatus for functional testing of a suspension device for a load, is used in combination with a suspension device such as a spring hanger or a constant support hanger holding a pipe run on a building structure and having at least one mechanical spring. The load is released from the suspension device and held with other devices. A hydraulic device is connected to the suspension device to be tested instead of the load for stretching the spring of the suspension device. The pressure necessary for stretching the spring and therefore the spring constant of the spring based on the operating travel of the spring, are ascertained and recorded with a pressure pickup and a recorder connected to the hydraulic device.
