Section SPS 341.75 - Inspection and testing(1) HYDROSTATIC PRESSURE TEST. Every secondhand vessel shall be inspected and given a hydrostatic pressure test at one and one-half times the maximum allowable working pressure at its new point of installation location before it is placed in operation. The test shall be witnessed by a certified inspector.(2) ALTERNATIVE TESTS. When the certified inspector determines that a hydrostatic test at one and one-half times the maximum allowable working pressure is not possible or desirable, the certified inspector may accept alternative means to determine if the vessel is safe for its intended use. Note: Where water is used in a hydrostatic test, the temperature of the water should not be less than 70oF and the maximum temperature during inspection should not exceed 120oF. If a test is conducted at 1.5 times the maximum allowable working pressure (MAWP) and the owner specifies a temperature higher than 120oF, the pressure should be reduced to the MAWP and the temperature should be reduced to 120oF for the close examination.
(3) EXEMPT VESSELS. Boilers and pressure vessels used for portable or emergency use shall be exempt from secondhand vessel test requirements.Wis. Admin. Code Department of Safety and Professional Services SPS 341.75
