Hydrostatic testing refers to the testing of pipes under pressure to verify that they are leak-free and structurally sound. This process involves filling the pipe with water and then pressurizing it to a specified level that exceeds normal operational pressures. The system is then monitored for any signs of leaks or failures. This testing is crucial for ensuring the safety and reliability of piping systems, particularly in applications involving flammable or hazardous materials.

The other options do not accurately describe hydrostatic testing. For instance, testing the pH level of water pertains to water quality assessment rather than structural integrity. Visual inspections can identify surface-level issues but do not involve pressure testing. Measuring the flow rate of water deals with the efficiency of a system rather than confirming its integrity under pressure. Thus, the correct answer highlights the specific nature of hydrostatic tests in assessing the leak-proof qualities of pipelines.
