Hydrostatic Test Report Template



Test Identification

1. The system, line or equipment number under test is recorded


Photo Comment

2. The approved test procedure or test pack reference is recorded


Photo Comment

3. The test boundary is defined by drawing and isolation point


Photo Comment

4. The test supervisor, witness and contractor are named


Photo Comment

5. The report reference number is recorded against the test pack


Photo Comment
Pre-Test Preparations

1. Welds within the test boundary are complete and released for testing


Photo Comment

2. Joints and fittings have been visually examined with defects cleared


Photo Comment

3. Test blinds are installed at every boundary and listed on a blind register


Photo Comment

4. End caps and closures are rated for the test pressure


Photo Comment

5. Valves within the boundary are set to the positions required by the procedure


Photo Comment

6. Equipment unable to withstand test pressure has been isolated or removed


Photo Comment

7. Instruments, relief valves and expansion joints are removed or blanked


Photo Comment

8. Temporary supports are rated for the weight of the system filled with water


Photo Comment

9. Spring hangers and supports are pinned where the procedure requires it


Photo Comment
Test Medium And Instrumentation

1. The test medium matches the procedure and is clean and free of debris


Photo Comment

2. Chloride content of the test water is within limits for stainless steel systems


Photo Comment

3. The metal temperature is above the minimum required to avoid brittle fracture


Photo Comment

4. Gauge calibration certificates are current for every gauge in use


Photo Comment

5. Gauge range is selected so the test pressure falls in the middle of the scale


Photo Comment

6. A second gauge or chart recorder is fitted where the procedure requires it


Photo Comment

7. The pressure relief device is set below the lowest rated component in the boundary


Photo Comment
Test Parameters

1. The specified test pressure from the approved procedure is recorded


Photo Comment

2. The actual test pressure achieved is recorded


Photo Comment

3. The required hold time and the observed hold time are both recorded


Photo Comment

4. Ambient and fluid temperatures at the start and end of the test are recorded


Photo Comment

5. Start and end pressure readings are recorded with the times taken


Photo Comment

6. Readings were taken at the intervals specified in the procedure


Photo Comment
Test Procedure And Safety Controls

1. The system was vented at all high points until free of air during filling


Photo Comment

2. The system was filled slowly at the rate stated in the procedure


Photo Comment

3. Pressure was raised in stages with a hold at each stage


Photo Comment

4. An exclusion zone was established and maintained throughout the test


Photo Comment

5. Personnel remained clear of blind flanges, closures and threaded connections


Photo Comment

6. Nobody approached the system while it was held at full test pressure


Photo Comment

7. The system was not left pressurised unattended


Photo Comment

8. Joints and welds were examined only after pressure was reduced to inspection level


Photo Comment
Results And Observations

1. Pressure was maintained for the full duration without a drop beyond tolerance


Photo Comment

2. The system remained free of visible leakage at all joints and connections


Photo Comment

3. No permanent deformation or distress was observed in any component


Photo Comment

4. Any leaks or defects found are recorded with their location


Photo Comment

5. Corrective work and any retest are recorded against the original test


Photo Comment

6. Observations are supported by photographs or gauge chart records


Photo Comment

7. The test meets the acceptance criteria stated in the approved procedure


Photo Comment
Depressurisation And Reinstatement

1. Pressure was released in a controlled sequence at the rate stated in the procedure


Photo Comment

2. Vents were opened before draining to prevent vacuum forming in the system


Photo Comment

3. The system was drained completely with no water left in low points


Photo Comment

4. The system was dried where the service requires it


Photo Comment

5. Test water was disposed of in line with environmental requirements


Photo Comment

6. Every blind listed on the register has been removed and signed off


Photo Comment

7. Relief valves, instruments and removed components have been reinstated


Photo Comment

8. Valves and supports have been returned to their operating positions


Photo Comment
Certification And Sign-Off

1. The responsible engineer has certified the test result


Photo Comment

2. The test was witnessed by the client or third-party inspector where required


Photo Comment

3. Contractor and client representatives have signed the report


Photo Comment

4. The approval carries signatures, dates and stamps as required


Photo Comment

5. Gauge calibration certificates are attached to the report


Photo Comment

6. Photographs and gauge charts are attached to the report


Photo Comment

7. The completed report is filed against the system and the test pack
