What percentage of zone valve outlets must be tested for compliance?

In medical gas systems, particularly in the context of compliance testing for zone valve outlets, it is required to test a minimum of 25% of all zone valve outlets. This percentage is critical for ensuring that the system maintains its integrity and safety standards, as zone valves play a vital role in controlling the flow of medical gases throughout a facility.

Testing this specific percentage helps ensure that there is a representative sample of the system's functionality and that potential issues can be identified and addressed without necessitating the testing of every single valve outlet. This approach also aligns with industry standards and regulations, which aim to balance thoroughness with efficiency in maintaining safety in healthcare environments.

In sum, testing 25% ensures that compliance is upheld while also allowing for practical resource allocation and management within healthcare facilities.
