Medical Gas Testing & Commissioning
Testing is the line between an installed network and one fit for patient use. We run a sequenced test programme — from pressure and leak testing to purging and verification of each gas identity at each outlet — and no zone is considered ready until every test has passed and its result is documented.
Test programme
- Pressure testing of the network and each isolation zone
- Leak testing of joints and terminal units
- Cross-connection testing between gases
- Purging and particulate clearance
- Gas identity verification at every outlet
- Purity and quality checks at terminal units
- Flow and pressure test at the worst-case outlet
- Alarm panel and sensor functional testing
Commissioning and handover
Once tests pass, the zone is commissioned under observation and handed over with test reports, as-built drawings and a familiarisation session covering isolation points, alarms and the emergency procedure.
Deliverables
- Documented test reports per zone
- Outlet results register
- Alarm test report
- Commissioning and handover record
- Operating team familiarisation
Where this service applies
- New project handover
- Return to service after modification
- Zone extension
- Periodic verification of an existing network
- Closing consultant observations

Frequently asked questions
What is the most serious fault testing catches?
Cross-connection between two gases. That is why gas identity is verified at every single outlet rather than on a sample basis.
Do you test a network installed by another contractor?
Yes, following a preliminary survey to confirm readiness for testing and to document any observations before starting.
Have a project or an existing facility that needs an engineering review?
Our engineering team can review your requirement and propose a solution suited to the application, the site and the applicable requirements.
