| Name | Low-expansion foam liquid foaming multiple and liquid separation time measuring instrument |
|---|---|
| Standard | UL162, EN 1568-1, NFPA 11 |
| Foam solution temperature | 15℃ ~ 20℃ |
| Ambient temperature | 15℃ ~ 25℃ |
| Foam generation system | Consists of a 5L/min foam gun, 1.5-level (0-1) MPa pressure gauge, pressure tank, air compressor, etc. |
| Foam gun | The flow rate measured using water at a pressure of 0.7 ± 0.03 MPa is (5.0 ± 0.1) L/min |
a) Prepare foam solution using fresh water according to required concentration. Control temperature to ensure produced foam temperature is within (15-20)℃.
b) Start air compressor and adjust inlet pressure of foam gun to (0.7±0.03) MPa. Wet inner wall of foam receiving tank, wipe clean, and weigh (m1).
c) After spraying for (5-10) seconds until stabilization, collect foam using eluent analyzer. Start stopwatch, scrape off overflowing foam, weigh (m2), and calculate mass of 25% eluent.
d) Remove receiving container from precipitation analyzer and place on balance. Place foam receiving container on support, ensuring precipitate is free of foam. Stop stopwatch when precipitated liquid reaches 25% of volume.
e) Calculate foaming ratio using specified formula.
