Pressure Relief Valve Testing and Traceable Records

Record identity before removal or exchange

Capture the valve tag, available manufacturer information and its installation reference. Where a spare is substituted, record both the removed and installed devices. Identical appearance does not establish that two valves have the same technical characteristics or approved application.

Provide the service history and known concerns to the testing team. Leakage, contamination, previous repairs or uncertain settings can affect the work required. Record gaps honestly instead of transferring details from an old certificate without confirming identity.

Tie pressure relief valve testing to the installed asset record so the device history remains traceable through exchanges.

Understand what the test record establishes

Bench testing and set-pressure verification provide evidence about the valve under the defined test conditions. The report should identify the test scope, observations, results and service work where applicable. Ask for unresolved findings and limitations to be clearly stated.

A bench-test result does not by itself verify the whole relief system. Device suitability, required capacity, installation arrangement and the equipment’s operating limits are separate technical considerations. If those matters are uncertain, refer them for competent review rather than treating a certificate as complete system approval.

Keep service work and authorisation controlled

Adjustment and servicing belong with appropriately competent personnel under a defined scope. Owners should not use general guidance to alter a relief valve setting. Any proposed change needs an approved basis that considers the protected equipment and relevant requirements.

Plan removal, temporary arrangements and reinstatement through site controls. Confirm who checks that the correct device is returned to the correct location and who resolves discrepancies between the equipment records and the valve documentation.

• Valve identity and protected-equipment reference.
• Test date, scope and responsible test provider.
• As-received findings and recorded service actions.
• Verified results and any outstanding limitations.
• Reinstallation or exchange record and final review.

Use the history for future planning

Link repeated leakage, service findings and replacement history to the asset record. These observations may prompt review of conditions or the service strategy. The timing of future testing should be determined on the relevant technical and jurisdictional basis, not a universal interval applied to every valve.
