Foam testing is not expensive and gives us the data required to make informed decisions about whether or not we are confident the entire system will perform as expected in an emergency (fire). We also get data to support longer term decision making in relation to environmental concerns about PFAS, PFOS etc. and options for new products.

Important tips:

  • Use clean plastic bottles that seal, avoiding anything that may have previously held detergent, oil, milk, juice etc.
  • Test at least annually
  • Clearly label any samples
  • For concentrates in a tank take a sample from top and bottom of the tank if you have any concerns about quality
  • For a produced foam sample remember to include a sample of induction water
  • When taking a produced foam sample activate the system long enough to remove any standing water
  • Remember to follow guidelines about spillage and clean up of produced foam, even from sample testing given the concerns about persistent organic pollutants.

Foam concentrate quality can be tested under laboratory conditions and compared to manufacturers specifications however for produced foam a facility benefits most from testing expansion and drainage on site using the foam generating equipment at operating conditions. This is particularly important for fluoroprotein and fluorine free foam. Field test kits are available for produced and concentrate testing and include items such as refractometer, scales, stopwatch, hydrometers, thermometer, manuals etc. but not to be confused with a “sample test kit” as per image. Sample test kits like those in the image are generally available for free issue but the follow up laboratory testing is a fee for service.

If you would like a free test kit simply ask us (fair use policy applies)
