STAND FOR SURFACE TENSION AND THE POWER TRANSFER DISTRIBUTION FACTOR MEASUREMENT
The purpose of the test is the tensometric measurement of the surface tension on the liquid-gas interface and the surface tension on the interface of two immiscible liquids, the so-called phase-to-phase tension of surfactant solutions and products containing these liquids.
STAND FOR MEASUING THE CONTENT OF SEDIMENT IN FOAM EXTINGUISHERS
The stand is used to measure the volume of sediment in the foam concentrates and other suspensions.
STAND FOR MEASURING VISCOSITY USING ROTARY VISCOMETER
The stand is used to determine the flow properties of both Newtonian and non-Newtonian liquids. It may also be used to define very precisely the pour point, indexes of thixotropy and rheopecty.
STAND FOR MEASURING LARGE-SCALE FIRE EXTINGUISHER EFFICACY OF HEAVY FOAM EXTINGUISHERS USED FOR SURFACE EXTINGUISHING OF FLAMMABLE LIQUIDS
The stand is used to measure the efficacy of the foam extinguishing agents. Tests are performed for fires of polar and non-polar substances. Extinguishing foam may be generated using supply water or, alternatively using seawater. The test may be performed for heavy, medium and light foam. In case of testing heavy foam the fire class and resistance to fire-return are defined.
STAND FOR MEASURING SMALL-SCALE FIRE EXTINGUISHER EFFICACY OF HEAVY FOAM EXTINGUISHERS USED FOR SURFACE EXTINGUISHING OF FLAMMABLE LIQUIDS
The test is performed to determine the type of extinguishing agent or for quality check of the foam. The determination consists of extinguishing a test fire using the foam generated out of concentrate according to the manufacturer’s recommendation. Extinguishing time and fire-return interval are measured.
STAND FOR MEASURING FOAM INDEX AND FOAM CONDENSATION TIME OF ALL TYPES OF FOAM EXTINGUISHERS
The method is used for the extinguishing foams generated by all types of foam extinguishers. During the testing, the following parameters are measured: foaming index, 5 min foam level, foam condensation time (25% and 50% condensation).
STAND FOR TESTING TECHNICAL PARAMETERS OF SORBENTS
This test can help to define whether a sorbent is useful for removing oil contaminants from hard surface and water surface. The following parameters are measured during the sorbent test: absorbency, granulation, chemical inactivity, bulk density, buoyancy.
STAND FOR TESTING PARTICLE DISTRIBUTION OF EXTINGUISHING POWDERS AND SORBENTS
Using this test it is possible to define the granulation of extinguishing powders, sorbents and other bulk solids. Testing is conducted using 0,040 mm, 0,063 mm, 0,125 mm, 0,180 mm, 0,425 mm, 4,0 mm sieves.
STAND FOR MICROSCOPIC TESTING
The stand is equipped with an optical microscope with a digital camera. Tests are performed in order to define the structure of extinguishing foam, emulsions, dry powders, sorbents and other bulk solids.
STAND FOR TESTING SURFACE TENSION AND WETTING ANGLE
The stand is used to measure the surface tension using „hanging drop” method and the wetting angle using the „sitting drop” method for surfactile solvents and products containing these substances. The test is based on analysis of the shape of the drop.
STAND FOR TESTING DYNAMIC SURFACE TENSION
The stand is used to measure dynamic surface tension using bubble measure method. The test subjects are surfactile solvents and products containing these substances.
STAND FOR MEASURING DYNAMIC VISCOSITY USING HÖPPLERA VISCOMETER
The test is based on the measuring of fall time of a ball with known density and known k value, in the tested liquid, under conditions defined in the relevant standard. The test is used to measure dynamic viscosity index.
STAND FOR MEASURING EXTINGUISHING EFFICACY OF PORTABLE EXTINGUISHERS AGAINST A CLASS FIRE
The stand is used to test extinguishing efficacy of extinguishing powders and portable extinguishers. A type test fires contain a pile of wood located on a steel construction of 250 mm height, 900 mm width and the length of the test fire.
STAND FOR TESTING EXTINGUISHING EFFICACY OF PORTABLE AND WHEEL FIRE EXTINGUISHERS AGAINST B CLASS FIRE
The method is used to test extinguishing efficacy of portable and wheel extinguisher with extinguishing agent based on water or powder. Test fires are prepared according to PN-EN 3-7 and PN-EN 1866-1 standards.
STAND FOR TESTING EXTINGUISHING EFFICACY OF PORTABLE EXTINGUISHERS AGAINST F CLASS FIRE
The purpose of the test is to measure extinguishing time of an “F” type fire using portable extinguishers. F class test fires, relating to the fires of flammable edible fats and oils are prepared using a tray simulating a deep fryer containing pure edible vegetable oil with auto-ignition temperature from 330°C to 380°C.
STAND FOR TESTING THE RANGE OF OPERATIONAL TEMPERATURES OF PORTABLE AND WHEEL EXTINGUISHERS
The stand is used for temperature conditioning of portable and wheel extinguishers. The purpose of the test is to measure the resistance of an extinguisher against high and low temperature. The test contains temperature conditioning of a product and comparison of the refraction index of the extinguishing index.
A stand for testing the extinguishing conductivity and electrical conductivity of the extinguishing jet, with a transformer enabling to obtain alternating voltage up to 42 kV.
