In Fire Cloud We Offer Foam systems Conductivity Test For AFFF Foam with concentration with 3% or 6 % to make sure the percentage of foam concertation to water concentration not excessed 3 % or 6 % .
Foam conductivity test procedures
- Fill three scaled bottles with 100 milliliters of water (the water must be same one used by deluge system connected with foam bladder tank)
- Remove 2, 3 and 4 milliliters of the three bottles and put 2 ,3 ,4 milliliter of foam concentration
- Mix this solution very well by checking measure the three-sample conductivity by conductivity meter and record the three-sample reading.
- Now we need to make real foam discharge and take three sample first sample after 20 second, second sample after 40 second and last sample after 60 second.
- Last step we need to take average of these three samples and compared with our tested sample
- The average reading must be between 3 % and 4% conductivity value by this way we are make sure the discharge concentrate has 3% which is very affectional to suppressed fire
