Automatic fire sprinkler systems prevent the spread of fire and are a requirement of some classes of buildings. Sprinkler Flow Testing is your guarantee that your Sprinkler System will perform as required. Each State in Australia has specific legislation together with the Building Code of Australia stating the requirement for the installation and maintenance of these systems. Maintenance activities are defined by Australian Standard AS1851, the Standard sets out the frequency of maintenance and activities for an automatic fire sprinkler system and its components. A flow test, also known as a water supply proving test is a functional test & measurement of the water supply for an automatic fire sprinkler system. Torvac Solutions technicians use the Ambit SF300 sprinkler Flow Tester, to ensure there is an adequate supply of water (flow and pressure) to satisfy the approved design & demand of the sprinkler system.

The performance criteria (baseline data) that forms the approved design of the automatic fire sprinkler system is recorded in as part of the required commissioning documentation and “Sprinkler Block Plan”. The block plan records details including the type, location & features of each water supply, the type, capacity and location of each pump-set, the type and the size and location of each sprinkler installation.

The block plan will also record the height of the most disadvantaged sprinkler head, along with other related information. The flow test measures the pressure and flow of each water supply including pumped water supplies. The pressure and flow rate is measured using calibrated gauges with the results recorded for later analysis.

Once test is completed, the results are entered into a report that includes the required pressure & flow criteria of the approved design for the fire automatic sprinkler system; details of each water supply, pumps and tanks.

Building Owners, Agents of Owners & Insurers

A flow test is ideally carried out yearly on the anniversary of the date the system was commissioned. Because each building is different, the time and requirements necessary to complete each test is also different. In some cases, the building owner, the agent of the owner or a representative of the owners insurance company may like to witness the test.

Precautions

Prior to carrying out a flow test, precautions should be taken to ensure the following:
• a job safety analysis is conducted and a safe work method statement is prepared; and
• there is sufficient capacity to cater for the discharge and to drain the large volumes of water necessary to carry out the flow test; and
• precaution set out in AS1851 has been considered and appropriate action taken.
