CNG Re-Testing Center

Cylinders and components must be re-tested at the intervals set by regulators to ensure continued safe operation.

Inspection & certification

Testing for safety and compliance

CNG cylinders have a defined service life and must be periodically re-tested in accordance with applicable standards and regulations. A re-testing centre verifies the structural integrity of cylinders and ensures valves and safety devices are functioning properly.

Proper inspection, testing, marking and documentation help ensure that only cylinders safe to return to service remain in use, and those beyond their safe service life are retired.
