The measuring device meets the requirements of multiple standards through the following designs:

1.Foaming multiple test: It uses a standard foam gun (such as PQ4/PQ8) and a measuring cylinder method, which meets the flow control and data acquisition requirements of ISO 7203-1 and EN 1568.

2.Liquid separation time measurement: The brass/stainless steel material of the liquid separation receiving tank and the automatic timing function meet the accuracy requirements of UL 162 and NFPA 11.

Pressure control:

The proportional control valve and electromagnetic flowmeter ensure stable liquid supply pressure (0.3–0.65 MPa), which is compatible with the test conditions of ASTM D1881.

Main technical parameters:

1 Composition: It consists of a low-multiple foam generation system, a standard foam gun, a low-multiple foam collector, and a low-multiple foam liquid analysis tester.

2 Low-multiple foam generation system: It consists of an air inlet pipe, a pressure-resistant storage tank, a pressure gauge, a foam liquid delivery pipe, and an adjustable bracket

3 Standard foam gun: When calibrated with water, at a pressure of (0.63±0.03)MPa, the water flow rate is (11.4±0.4)L/min

4 Low-expansion foam collector: made of stainless steel

5. Liquid analyzer: made of brass; calibrate the volume of the foam receiving tank with water to an accuracy of 1 mL

Other accessories:

1 Air compressor: 0.8MPa, flow rate 30L/min;

2 Thermometer: graduation value 1℃, mercury thermometer;

3 Measuring cylinder: 500mL, graduation value 10mL;

4 Balance: 1000g/0.1g;

5 Stopwatch: graduation value 0.1s.

Measurement environment requirements:

1 Ambient temperature: (15~25)℃

2 Foam temperature: (15~20)℃
