Conducting a hydrostatic test on a boiler primarily aims to check for leaks. This testing method involves filling the boiler with water and applying pressure greater than the normal operating pressure. The test allows operators to identify any potential weaknesses or defects in the boiler's structure that could lead to leaks. By observing the equipment for any water seepage or pressure drop during the test, the integrity of welds, joints, and material can be validated.

While verifying operational safety and confirming material strength are also important aspects of boiler functionality, those aspects can be evaluated through other tests and inspections, such as pressure tests, inspections of materials, or operational checks under normal conditions. Establishing thermal efficiency would not be the focus of a hydrostatic test; instead, thermal efficiency is usually assessed through performance testing during actual operations.
