Question: 1 / 495

What are the minimum and maximum temperatures allowed when performing a hydrostatic test?

50-90°F

60-100°F

70-120°F

The appropriate temperature range for conducting a hydrostatic test is critical for ensuring the accuracy and safety of the test results. The minimum of 70°F is essential because it helps to prevent issues like freezing of the water, which can affect the integrity of the test. A maximum of 120°F is also stipulated to avoid the introduction of problems such as increased pressure that could compromise the safety of the test or the testing apparatus itself.

Operating within this temperature range allows for proper material expansion and the accurate assessment of the boiler's integrity under pressure. Additionally, it helps guarantee that any potential flaws or weaknesses in the boiler are revealed without the risk of thermal shock or other temperature-induced variables skewing the outcome of the test.
