This app assists with the field testing of firefighting produced foam (finished foam) from proportioning systems covered by key International Standards from NFPA, BSI ICAO and IMO and also allows the user to create their own test Standards. Using the produced foam testing method from NFPA11:2021 Annexe D, the app allows the user to generate the best fit calibration line from Refractive Index, Refractive Index (%Brix) or Conductivity measurements taken from standard solutions and then determines the foam concentration from the produced foam measurement. The app will assess whether the foam concentration is within the allowable range of the selected Standard and generates a one page Produced Foam Test Report that can be customised to include the testers company information and then saved emailed or printed. Test data can be saved in the app for future reference and the app includes helpful site testing tips which are an extract from the Produced Foam Training Course offered by Fire Foam Training Ltd. The app allows up to ten tests to be executed and an in-app purchase is available allowing unlimited tests the can be saved and allows the generation of the Produced Foam Test Reports.
