A leak test is a method to verify that an object, product or system operates within a certain leak limit. Leak testing can be described as a broad term that covers a variety of technologies. There are different leak testing methods that are performed to determine leaks of a product or package.

Leakage occurs when liquid or gas flows through an object due to an imperfection in manufacturing or defect, such as cracks, holes or weak seals. These defects create high- or low-pressure areas within a product. This forces the liquid or gas to flow from the high pressure area to the lower-pressure. These are the primary method of identifying leaks using pressurized air.
Leak Testing Methods
There are many types of leak testing methods that can be used, each with different leak rate limits. And one of them is the pressure decay leak testing method. The pressure decay test is used to determine if a part leaks or not within a specified limit of leakage.
Pressure decay leak testing has many benefits:
- Fast (depending upon the internal test volume of a piece)
- It is easy to set up
- It is only necessary to compress the clean
- Dry air
- There is no pre- or post-processing required
It is crucial to determine the leak rate in order to choose the best leak testing method.
