How do we test the sprinklers?

Using one of our designated sprinkler head test rigs, the FPA test laboratory will evaluate the condition and operational performance of a sprinkler head. The tests will include:

  • Visual inspection of 100% of the samples
  • A minimum of 75% of the heads will be subjected to a ‘function test’ - this has two parts: a water based test to detect leakage in the heads, and a gas flame activation test to check satisfactory operation of the heads. Once activated the water flow is monitored and assessed.
  • The remaining 25% may also be subject to either an operating temperature test - where heads are placed in a water bath which is heated gradually until the thermally sensitive element activates - or further function testing.
  • Post testing visual inspection, paying particular attention to the waterways and deflector plate.
  • Further testing if needed; for example if the heads were blocked.
  • Results and recommendations will be provided in a detailed report within four weeks of receiving the heads.
