2020年2月8日 · A leak test is a procedure used to determine if an object, product, or system functions within a specified leak limit. A leak occurs when a gas or liquid flows through an object via an imperfection or manufacturing defect such as a hole, crack or weak seal.
Ponding test with fluorescent dye gives the direct prove of the water leakage. With the aid of UV photography , the fluorescent effect can be clearly inspected on the affected area (e.g. ceiling) if the fluorescent dye water leaks from the possible source of water leakage (e.g. bathroom)
leakage test in which a liquid containing a dye or fluorescent oil is driven by a pressure differential into the leak in the wall of the object to be tested and is then detected by a visual inspection on the other side
2020年10月24日 · Leak testing is performed for three basic reasons: to prevent material leakage loss that interferes with system operation; to prevent fire, explosion, and environmental contamination hazards or nuisances caused by accidental leakage; to detect unreliable components and those whose leakage rates exceed acceptance standards.
