Leak testing is an important quality control measure in manufacturing. This article provides guidance on determining leak testing specifications by exploring factors and modifying existing specifications or creating new ones.

Plant engineers and quality departments often struggle with zero point drift during air leak testing, where the initial zero reading shifts over time, leading to frequent adjustments of the leak test instrument. This article addresses the causes of zero drift, commonly attributed to changes in shop floor temperature, and provides strategies to minimize or eliminate this issue for improved efficiency in quality control processes.

Some manufacturers will use a single-point calibration system to measure volumetric flow—however, a two-point calibration provides a much higher level of accuracy.

For lithium-ion traction batteries, leak detection is imperative for battery performance, longevity and safety, especially the prevention of fires.

From airbags to air-conditioning units and fuel rails, from anything implanted in the body to hermetically sealed enclosures for integrated circuits, there are some instances where the acceptable leak rate is so small as to be practically zero. Few air leak test methods, such as pressure decay, have the necessary detection range.
