RT Journal Article SR Electronic T1 How and Why Would You Do a Pressure Holding Test on an Aseptic Installation for which You Want to Check the Integrity? Theory and Practical Example JF PDA Journal of Pharmaceutical Science and Technology JO PDA J Pharm Sci Technol FD Parenteral Drug Association (PDA) SP 71 OP 79 VO 64 IS 1 A1 Olivier Chancel A1 Raoul Grissely A1 Magnus Stering A1 Luc Pisarik YR 2010 UL http://journal.pda.org/content/64/1/71.abstract AB This paper uses the Boyle-Mariotte Law to restate a few general principles and applies them to rationalise pressure holding tests on sterile installations. The authors offer a methodology to achieve this, as well as a few mathematical models to determine test durations and acceptance limits, as functions of the breach sizes to be considered and the measurement instruments used. Apart from the theoretical approach, readers are offered a few examples to illustrate the models.© PDA, Inc. 2010
