Question: 1 / 495

What is the maximum water temperature that can be used for a hydrostatic test?

100°F

120°F

The maximum water temperature for conducting a hydrostatic test is set at 120°F. This temperature limit is primarily established to ensure safety and material integrity during the testing process. At higher temperatures, the water’s pressure can lead to increased risks, such as rapid expansion or failure of the test equipment and the system being tested. Maintaining a maximum of 120°F helps to achieve a balance between effectiveness in detecting leaks or weaknesses in a system while minimizing any risk associated with the testing process. Using water at this specified temperature also ensures that the material properties of pipes, fittings, and other components do not undergo detrimental changes that can occur at higher temperatures.
