• A calibrated pressure relief valve set at a cracking pressure of 330 bars shall be installed in the line.
• A test pump shall be connected to the piping ensuring that the pump can be disconnected from the manifold when the pipes are pressurized.
• The manifold piping shall then be slowly filled with clean potable water using the pump. During water filling, the test crew must ensure that the system is completely vented.
• The piping system shall be slowly pressurized giving 5 minute interval in between every 100 bar. Pressure increase until a pressure of 300 bars is attained.
• A visual inspection shall be made on every joint for leakage. If any leaks are found, the system shall be drained and necessary repairs shall be done.
• When it is evident that there are no leaks or drop in the indicated pressure, the pressure shall be maintained for a period of 2 hours at ambient temperature.
• Record the readings indicated in the pressure gauge after every 60 minutes.
• On satisfactory completion of the test, the water in the manifold piping shall be drained off and the pipes shall be dried up by blowing air.
• Fill in and complete the test certificate and obtain the necessary signatures.
• The test certificate shall be completed with necessary signatures obtained.

7.11 INTEGRITY TEST:

7.11.1 PRETEST PROCEDURE

 7.11.2  PREPARATIONS                    

• Ensure that the necessary work permit (if required) is obtained.
• Barricade the area.
• Inspect the room thoroughly for any openings not sealed, windows / doors opened.
• Ensure that the HVAC system is switched off and all the inlet / outlet dampers are closed.

NOTE:

The air-conditioning / ventilation system must be closed during the test. The required isolation duration will be around 2 hours for each protected area.

 7.11.3 TEST PROCEDURE

• The procedure involves the fitting of a variable speed fan unit into an existing doorway by means of an adjustable door frame. The fan is used to pressurize and de-pressurize the enclosure with a known / measured quantity of air of very low pressure.
• Leakage is quantified by measuring the air flow rate and the developed pressure within the enclosure. A computer is used to calculate the “effective leakage area” (ELA) which is the sum total of all leakage sites within the perimeter of the enclosure.
• The test is essentially a two part test.
• The first part of the test uses a fan that quantifies the leakage areas within the enclosure and provides a calculation of the effective leakage area (ELA).
• The second part of the test involves the use of a computer model to predict whether the INERGEN gas would be held for a specified period.
• Personnel can be inside the enclosure during tests however, they must remain inside until tests are completed.

7.11.4 Part 1: FAN TEST

•  Ensure all pre-works were completed.
• Complete the fit-out of adjustable door frame and fan unit in door way. Connect the manometer and the pressure sampling tubes.
• After the equipment set-up, finalize preparations for the actual test.
• Fix the sign stating “DO NOT ENTER / CLOSE DOOR – FAN TEST IN PROGRESS”. The sign shall be posted in English.
• Fill the integrity test record form except the readings to be taken during the test.
• Take the readings of static pressure within the enclosure as appropriate.
• Perform Depressurization Test – the fan to be switched on and by varying the quantities of air blown into the protected enclosure, it will create negative pressures within the enclosure.
• Perform Pressurization Test – the fan to be switched on and by varying the quantities of air blown out of the protected enclosure to create Positive pressures within the enclosure.

7.11.5 Part 2: COMPUTER CALCULATION

Following the completion of the Pressurization and Depressurization tests, the readings taken are entered into the computer along with the details of the INERGEN gas fire extinguishing system and calculation of the effective leakage area (ELA) are made as well as the prediction of the INERGEN gas retention time on the basis of design parameters.

In case the enclosure does not hold 10 minutes retention time, then the client may need to obtain services of Specialist Consultant to seal the protected enclosure.

After completion of the above, the room can be turned back to its normal stage.

7.11.6 INTEGRITY TEST REPORT

Upon completion of the tests, a full report shall be prepared and test results shall be compiled by the Engineer.
