Leak Testing
Principles. Leak testing is concerned with the flow of liquids or gases from pressurized or into evacuated components or systems intended to hold fluids. The principles of leak testing involve the physics of fluid (liquids or gases) flowing through a barrier where a pressure differential or capillary action exists.
Leaking fluids (liquid or gas) can propagate from inside a component or assembly to the outside, or vice versa, as a result of a pressure differential between the two regions or as a result of permeation through a barrier.
The importance of leak testing depends on the size of the leak and on the medium being leaked. Leak testing encompasses procedures that fall into these basic functions: leak location, leakage
measurement and leakage monitoring.
Applications.
Like other forms of nondestructive testing, leak testing has a great impact on the safety and performance of a product. Reliable leak testing decreases costs by reducing number of reworked products, warranty repairs and liability claims. The most common reasons for performing a leak test are to pre\'ent the loss of costly materials or energy; to prevent contamination of the environment; to ensure component or system reliability; and to prevent the potential for an explosion or fire.
Functions of Leak Testing
Leak testing is a form of nondestructive testing used in either pressurized or evacuated systems and components for detection and location of leaks and for measurement of fluid leakage. The word leak refers to the physical hole that exists and does not refer to the quantity of fluid passing through that hole.
A leak may be a crack, crevice, fissure, hole or passageway that, contrary to what is intended, admits water, air or other fluids or lets fluids escape (as with a leak in a roof, gas pipe or ship). The word leakage
refers to the flow of fluid through a leak without regard to physical size of the hole through which flow occurs. Fluid denotes any liquid or gas that can flow.
Reasons for Leak Testing
Leaks are special types of anomalies that can have tremendous importance where they influence the safety or performance of engineered systems. The operational reliability of many devices is greatly reduced if enough leakage exists.
Leak testing is performed for three basic reasons: (1) to prevent material leakage loss that interferes with system operation; (2) to prevent fire, explosion and environmental contamination hazards or nuisances caused by accidental leakage; and (3) to detect unreliable components and those whose leakage rates exceed acceptance standards.
ASNT Level 3 Leak Testing Course covers the purposes of leak testing are to ensure reliability and serviceability of components and to prevent premature failure of systems containing fluids under pressure or vacuum. Nondestructive methods for rapid leak testing of pressurized or evacuated systems and of sealed components are thus of great industrial and military importance.
Relationship of Leak Testing to Product Serviceability
Most types of nondestructive tests are designed to aid in evaluating serviceability of materials, parts and assemblies. ASNT Level 3 Leak Testing Course Tests are used for determining integrity of structure, measuring thickness or indicating the presence of internal and surface anomalies. For most nondestructive test methods evaluation is indirect; the quantities measured have to be properly correlated to the serviceability characteristics of the material in question.
Thus, the use of indirect tests depends on the interpretation of the test results. Leak testing procedures, on the other hand, facilitate direct evaluation. The measured leakage rate represents the physical effect of a faulty condition and thus requires no further analysis for practical assessment.
