Which test verifies the integrity of pressure containment components such as pipes or cylinders by using water under pressure?

• A. Proportioning
• B. Hydrostatic Test
• C. LDH
• D. Expellant Gas

Answer: (C)

Hydrostatic testing is the process of verifying the integrity of pressure-containing components by filling them with water and applying pressure. Water is essentially incompressible, so when you pressurize the system to a specified level (often higher than normal operating pressure) and hold it, any weakness, flaw, or leak will show up as water escaping or a drop in pressure. This method is widely used on pipes, cylinders, tanks, and other containment parts to ensure they can safely withstand the intended service pressure. The description in the question matches this method: testing by using water under pressure to check for leaks and structural soundness. Proportioning relates to mixing agents with water for firefighting foam, not validating pressure containment. Large Diameter Hose is a tool for delivering water, not a test method. Expellant gas implies using gas under pressure, which is a different type of test and not what’s described here.
