The 2008 revision of TR 26 was a landmark document. It moved the industry away from a prescriptive "checklist" mentality toward a more holistic, systems-based approach. It introduced the concept of the "Contamination Control Strategy" (CCS) before it became a buzzword in Europe. However, as technology advanced, the 2008 version began to show its age, particularly regarding the definitions of cleanroom classifications and the handling of modern robotics.
In the world of pharmaceutical manufacturing, few documents carry as much weight in the sterile processing arena as . Officially titled “Sterilizing Filtration of Liquids” (current revision: TR 26, Revised 2008), this document is the global industry standard for the validation and operation of sterile filters. pda technical report 26
