Why is Foam Testing required?

Foam testing is needed to ensure that stocks of Foam concentrate held are in good condition. AFFF manufacturers offer a minimum Shelf Life of 10 years provided they are stored in original and unopened containers. It is impossible to tell if foam concentrate is of operational quality by smelling or looking at it. Annually Foam Concentrates should be tested to ensure that fire-suppression foams continue to perform as required for their specified applications.

Kemex testing includes the following

Physical and Chemical Test:
  • Appearance
  • Specific Gravity
  • pH
  • Viscosity
  • Surface Tension
  • Freeze Point
  • Sediment
Performance Test:
  • Expansion
  • 25% Drainage
  • Fire Extinguishment Properties
  • Burnback Properties
Quantity Required:
  • 1-2 Ltrs for Physical and Chemical Testing
  • 5-10 Ltrs for Performance Test

Additional Test and Services are available as per Clients requirement.

Dry Chemical Powder Testing

Fire-fighting dry chemical products are compatible with foam concentrates, allowing twin-agent application. During the manufacturing process, it is treated with flow promoting and moisture repellent additives and checked for particle size..Minimum Shelf Life given by the manufacturer is for 5 years provided they are stored in original and unopened containers. Annually Dry Chemical Powder should be tested.

Kemex testing includes the following

Physical and Chemical Test:
  • Chemical Content
  • Apparent Density
  • Particle Size
  • Hygroscopicity
  • Caking Test
  • Water Rpellency
  • Moisture Content
  • Free Flowing
Performance Test:
  • Foam Compatibility
  • Fire Knock Down Test
  • Fire Performance
Quantity Required:
  • 1-2 Kgs for Physical and Chemical Testing
  • 5-10 Kgs for Performance Test

Additional Test and Services are available as per Clients requirement.

Testing of Equipments

Our Teams of highly qualified technicians in modern, purpose-built laboratories analyse samples of all types of foam to the highest standards. With knowledge and experience of evaluating foam samples gained over many years, Angus Fiire staff are uniquely placed to interpret the results and provide reliable recommendations about the suitability of foam for use in an emergency. Analytiical chemistry laboratories that do not specialise in fire fighting foam testing are unable to offer such specialist expertise. The results are reported quickly with a comprehensive test report.


The process is described in three stages as follows:

The cylinders in the fire suppression systems needs periodic check & maintenance & certification for the same the cylinders are removed from the system & taken to the plant. These cylinders are super pressured with nitrogen to 25bar or 42bar. The fire suppression gas needs to be recovered from the cylinder. Cylinder is attached to Kemex Reclaiming Machine for the same & gas is recovered by maintaining cylinder inner atmosphere to -20oc. There is significant amount of gas loss occurs during reclaiming which is at a much lower quantity than others due to additional safety features in Kemex Reclaiming Machine.
The emptied cylinders are tested for hydrostatic stretch test subject to five years from the date of manufacturing as per, Gas Cylinders Rule (2004) & IS: 5844. Also the gas in cylinder reclaimed is checked for purity by using Gas Analyzer and Gas Chromatography. The certificate for the cylinder HT test is issued which is approved by Chief Controller of Explosives.

Vacuum a cylinder before filling

Before the cylinder filled with gas it needs to be vacuumed to remove left impurities if any of previous filled gas in the cylinder. We have IHVP MAKE vacuum pump (model IVP 250) & is a direct drive rotary double stage high vacuum pump. Cylinders are vacuumed to a range from -400 to -760mm of hg pressure.

Procedure for filling of cylinders:

Pump is connected between two manifolds one is inlet manifold & other one is outlet manifold Pump is driven by compressed air at 6.5 kg/cm2. Compressor is having the safety relief valve calibrated at 8.0kg /cm2. Each manifold have a separate safety relief valves set at 12 kg/cm2. Mother cylinder will be connected to inlet manifold & cylinder to be filled will be connected to outlet manifold by flexible hose & cylinder will be placed on weigh scale & filled. The cylinder will be super pressure with nitrogen to 25bar or 42 bar & will be checked for leak test.
