Manycon is the best recommended integrity testing team in Saudi. It is simply a way to measure the leakage of an enclosure. A large fan is temporarily installed in the doorway of the room to be tested, with the fan blowing into the room (pressurizing the room). The fan speed is adjusted to obtain flow pressure equivalent to the pressure exerted during a fire suppression system discharge. The fan is then reversed on the door to draw air from the room (depressurizing the room). The airflow and pressure readings obtained are entered into a computer program designed to calculate the equivalent leakage area (ELA) for the room. When a room has a suspended (drop) ceiling, then the below ceiling leakage area (BCLA) is calculated as one-half the total ELA and is used in the calculations for retention time. Given that most gaseous chemical agents used for fire suppression are heavier than air, the agent will begin to leak out of any lower level penetrations left unsealed.
Manycon is the top FM 200 integrity testing company in Saudi. The ability for the gaseous agent to be retained in the protected room for an extended period of time is critical to the performance of any total flooding clean agent fire extinguishing system. NFPA 2001, Standard on Clean Agent Fire Extinguishing Systems, requires that a minimum concentration of 85% of the adjusted minimum design concentration be held at the highest level of combustibles for a minimum period of 10 minutes. Those installing these systems are required to perform a Room Integrity Fan Test to assure the protected room will hold the agent for the required period of time.
Manycon is the top notch recommended company in Saudi for Blower door fan test and Air leak test in Saudi. Because of its nature, a Door Fan Test will always calculate the worse case leakage for the room. It draws air through leaks in the room and under the floor as well as above the suspended ceiling to predict the descending interface of the suppression agent. The length of time it takes for the descending interface to reach the minimum protected height identifies the concentration hold time.
INTEGRITY ROOM TEST PROCESS:
1. Initial Assessment: Manycon begins by reviewing the specifications and requirements of the room to be tested. This includes understanding the purpose of the room, its design specifications, and any relevant industry standards or regulations.
2. Test Planning: Based on the initial assessment, Manycon develops a comprehensive test plan. This plan outlines the testing procedures, equipment requirements, acceptance criteria, and schedule for the room integrity test.
3. Pre-Test Preparation: Manycon coordinates with the client to ensure that the room is prepared for testing. This involves sealing all openings, such as doors, windows, vents, and ducts, to create a sealed enclosure.

Purpose: The primary purpose of room integrity testing is to verify that the enclosure can maintain its intended environmental conditions, which are critical for the processes or equipment housed within it. This is particularly important in environments where precision control is necessary, such as pharmaceutical manufacturing, data centers, or sensitive research facilities.
Methodology: Room integrity testing typically involves pressurizing the room with a non-hazardous gas, such as nitrogen or clean dry air, to a specified pressure level. A calibrated fan or blower is then used to measure the rate at which the pressure decays over time. By analyzing the rate of pressure decay, technicians can assess the overall integrity of the room's envelope, including doors, windows, walls, ceilings, and penetrations.
Acceptance Criteria: The acceptance criteria for room integrity testing are usually based on industry standards and regulatory requirements specific to the type of facility and its intended use. Common standards include ISO 14644 for cleanrooms and data center industry guidelines such as ASHRAE TC 9.9. These standards define permissible levels of pressure loss and leakage rates based on the class or rating of the room.
Reporting: Upon completion of the testing, a detailed report is typically generated, documenting the test methodology, equipment used, measured pressure decay rates, and compliance with acceptance criteria. Any areas of concern or deficiencies identified during the testing may also be noted, along with recommendations for corrective actions if necessary.
Frequency: Room integrity testing is typically conducted initially after construction or renovation of the facility to verify compliance with design specifications. Subsequent testing may be performed periodically as part of ongoing maintenance and validation activities to ensure continued integrity and compliance with regulatory requirements.
Importance: Ensuring the integrity of the room environment is critical for maintaining product quality, data security, and safety. Inadequate room integrity can lead to contamination, equipment malfunction, data loss, or other adverse effects, potentially resulting in costly downtime, product recalls, or regulatory violations.
Why is Room Integrity Testing Important?
A room with proper room integrity is vital to ensuring that fires are contained, and damage is minimised. These systems can help prevent the spread of fire, smoke and toxic gases to other parts of the building. If not properly secured, smoke and fire can result in extensive damage and loss of life. Room integrity testing is also crucial for reducing the impact of fire on critical infrastructure and preserving sensitive information. By conducting room integrity tests, building owners can reduce the risk of damage to equipment, facilities and sensitive information.
The means to test the room for ‘ tightness ‘ is by the Retrotec Room Integrity Door Fan Pressure Test means. A calibrated and certified axial flow fan is latched into rigid expandable panels that fill the opened door frame space.By running the calibrated fan at a certain speed thus generating pressure into / from the space, and by monitoring the pressure differential within and external to the room, that flow rate is actually measured, data inputted to software together with the protected height and the weight of gas ( FM200 / FE25 / Novec 1230 or Proinert / Argonite / Inergen Inert Gas, yes inert gas is basically air, but it still has weight!) and a descending interface height hold time, or mixing concentration result is obtained.The performance of any fire suppression system can only be guaranteed when serviced regularly through a professional maintenance solution. We always recommend that room integrity testing should be part of an annual service and maintenance package, to ensure that on discharge, the suppression agent achieves and maintains the correct concentration, at the appropriate height for minimum required timeframe.Most rooms housing mission critical equipment are constructed with the perimeter walls extending from “slab to slab” in a manner that creates a fire rated barrier around the room. Because of their construction, these rooms will have fewer leaks and have a much greater chance of passing a standard Room Integrity Fan Test. However, it is possible to achieve a successful test in a room where the perimeter walls do not extend from “slab to slab” but instead extend only to above the suspended ceiling. When preparing a room to retain a gaseous fire suppression agent, the walls and slab must be inspected for penetrations and leakage points. All areas of concern must be properly sealed with fire retardant materials and doors fitted with pressure seals around the jams and threshold.
Recommendations For Room Integrity Testing:
Room integrity tests should be conducted immediately after a gaseous fire suppression system has been installed, and routinely every year thereafter to validate the integrity of a protected area.
Over time the characteristics in a room may change, which results in new leakages and affects the retention time within an enclosure. Any alterations made to the structural perimeter of an enclosure, such as holes, cracks, cable entry points, electrical conduit points, and any other voids will require retesting of the room to ensure that all leakage points are adequately sealed.
For accurate readings and minimal interference, all air conditioning units and HVAC systems passing into the enclosure would need to be shut down or temporarily sealed during testing. Air conditioning units introduce a new air supply into the enclosure which disrupts the testing process.
Room Integrity Testing Equipment:
The equipment needed to conduct room integrity tests include:
Expandable Door Panels
A Variable Speed Fan
Manometer
A Dedicated Portable Computer.
Standards for room integrity testing:
Corresponding Room Integrity Testing Standards :
ISO 14520,
NFPA 2001
ISO 15004
A typical room integrity test procedure consists of two parts, the Door fan test and the computer calculation.
DOOR FAN TEST:
The first part of a room integrity test involves the use of a fan mounted into a door panel to introduce a flow of air into the room. The fan blows air into a protected enclosure to create positive pressures that simulates the pressures exerted during a fire suppression system discharge.
The fan is then reversed to draw air from the room, creating a depressurised condition within the enclosure. Pressure and air flow rate readings are taken for both the positive and negative pressure tests.
COMPUTER CALCULATION:
The second part of a room integrity test involves inputting the pressure test readings into a computer, along with the details of the fire suppression system and the dimensions of the protected enclosure.
Specialised computer software then calculates the predicted Equivalent Leakage Area for the enclosure, as well as the room’s gas retention time. If the retention time is above 10 minutes, the room passes the integrity test. In instances where the retention time is below 10 minutes, the room fails the integrity test and identified leakages would need to be permanently sealed.
Once a test has been completed, a full room integrity test report should be produced detailing the date the test was conducted, identified leakage areas, pressurisation results, predicted retention times, and all other relevant information.
