What Is AAMI ST108?

AAMI ST108 is an American National Standard that provides guidance on the quality of water used in the processing of reusable medical devices. It was published in 2023 and supersedes the previous standard, AAMI TIR34.

The standard covers the following topics:

  • Water quality requirements for cleaning, rinsing, and sterilizing medical devices
  • Methods for monitoring and testing water quality
  • Maintenance and troubleshooting of water systems
  • Risk management for water quality

AAMI ST108 is intended to help healthcare facilities ensure that the water used to process medical devices is of sufficient quality to prevent the spread of infection. The standard is based on the principles of risk management and takes into account the latest scientific evidence on the relationship between water quality and patient safety.

Some of the key requirements of AAMI ST108 include:

  • Water used for cleaning and rinsing medical devices must be free of bacteria, endotoxins, and other contaminants.
  • Water used for sterilizing medical devices must meet the requirements of the specific sterilization process being used.
  • Water systems must be monitored and tested on a regular basis to ensure that they are meeting the required water quality standards.
  • Any problems with the water system must be identified and corrected promptly.

AAMI ST108 is an important resource for healthcare facilities that need to ensure the quality of water used in the processing of medical devices. By following the requirements of this standard, healthcare facilities can help to protect patients from the risk of infection.

In addition to the requirements listed above, AAMI ST108 also provides guidance on the following topics:

  • The design and installation of water systems
  • The selection of water treatment equipment
  • The training of personnel responsible for water quality

The standard is intended to be used by a variety of stakeholders, including healthcare facilities, water treatment companies, and equipment manufacturers. It is a valuable resource for anyone who needs to ensure the quality of water used in the processing of medical devices.
