While filter ratings are a simpler integrity test for less critical applications is a Pressure Decay Test. This requires the same air (or nitrogen) source and an accurate pressure gauge but does not require a mass flow meter. This type of test can be performed before and after use and is sensitive enough to detect very small leaks.

Most Commonly Asked Filtration Question Series Integrity Testing is a requirement of suppliers selling absolute-rated membrane cartridge filters for microbial reduction or removal of yeast and mold. Test results are validated to remove specific organisms and a certificate is included with each product proving the quality of the filter. In addition to vendor testing, manufacturers in different industries perform their own Integrity Tests for critical processes. In pharmaceutical and bioprocessing, industry regulations call for Integrity Testing at prescribed intervals in a process. In the Food & Beverage industry, although not mandatory, Integrity Testing is a strategic move to assuring product safety and quality. Today we'll discuss the need and steps for in-process integrity testing.
