As defined in NTN 168 of ANPI, any automatic foam extinguishing system must be the subject of a very precise check on foam quality. All analytical parameters are found in the technical note ANPI NTN 168 and will be used as a specific reference for each extinguishing system and to check that the foam does not deteriorate over time.
The quality analysis must be conducted during acceptance and then must be checked periodically according to the schedules defined in the technical note, where we will check that the foam retains all of its qualities.
