Validation and verification of medical gas installations

Written By Jolanta Szubert

Why is it important to Validate and Verify Medical Gas Installations?

The objective of testing and commissioning is to ensure that all the necessary safety and performance requirements of the MGPS will be met. Testing and commissioning procedures will be required for new installations, additions to existing installations and modifications to existing installations. The scope of work will dictate the specific test programme required.
