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.
