A test system and method for in line testing of shock suppressor shut-off valves is provided. Vacuum and fluid canisters are mounted to a backpack that can be carried by maintenance personnel to the operating locations of shock suppressors. The fluid canister contains a fluid for being driven through the shut-off valves of the shock suppressor during testing. Fluid lines interconnect the canisters and the shock suppressor. A valve assembly is disposed within the fluid lines for regulating the rate of flow of the fluid from the fluid canister to the shock suppressor. The system further includes structure disposed within the fluid lines for evacuating the fluid lines and the valve assembly prior to testing of the shut-off valves. Structure further is provided for measuring and recording the velocity of the fluid flowing to the shock suppressor, such that the measured velocity provides an indication of the required flow rate within the shock suppressor necessary to close the shut-off valves and to lock the shock suppressor, to thereby test the operating characteristics of the shock suppressor shut-off valves without removal of the shock suppressor from its housing and mountings.
