Water Management for Medical Device Processing
A new AAMI standard is here
ANSI/AAMI ST108:203 - Water for the processing of medical devices
As the primary source of standards and guidance for water quality, The Association for the Advancement of Medical Instrumentation (AAMI) has provided a new standard, designed to help protect patients and instruments:
- Replaces AAMI TIR34:2014/(R) 2021 Standard focused on minimum water quality requirements for processing medical devices
- Sets different categories for water used in sterile processing: utility water, critical water and steam
- Details when and where to use water in each category
- Provides information on how to maintain required water quality
- Sets performance criteria for a water treatment/delivery system and monitoring program
