Operating Procedures of Glow Wire Testing

Glow wire tester will specify the material and shape of the electric wire with a large current heated to the test temperature, the specified pressure (1.0N) vertical hot test sample 30s, depending on the test and bedding is ignited or burning time to determine Electrical and electronic equipment, the risk of fire products; Determination of solid insulation materials and other solid combustible materials, ignition, ignition temperature, flammability and flammability index.

 Glow Wire testing Apparatus Operating procedures1, glow-wire test machine before the preparation of the operation2, be sure to read the use of instructions, and follow the instructions step, followed by operation;3, do not use non-original accessories, so as to avoid danger;4, glow wire test machine on the room to the oil ventilation equipment (or with a special ventilation hood in a small laboratory), in order to test the exhaust after the discharge.5, the two matching weights with copper wire (connected to the sample rack) by the left side of the two pulleys (through the corresponding hole) hanging under the bracket plate.6, according to the standard requirements of interest and clamping samples.7, close to the adjustment of the switchA. The nut that is fixed to the switch is loosened and moved left and right;B. Press the "left button" car automatically forward, when the sample contact with the hot wire, the hand close the switch, so that the car stopped before the fixed and close the switch.C. Press the "Heating" button to adjust the current adjustment knob. According to the requirements of the sample, adjust the appropriate current value, while the temperature is required to meet the test requirements of the required temperature.


 When the test piece touches the glowing wire head, the limit electromagnet is released and the 1N weight can only be moved forward by 7mm.When the experiment is finished, eject the heating button and then turn the current adjustment knob to the minimum.

    The glow wire test for plastics is to determine the resistance to fire insulating parts. And the glow wire test simulates the situation of what the plastics material will happen when contact with an over-heated part.

Determination of air permeability of a fabric-air permeability tester

Fabric air permeability is a measure to what extent it gives air passing through the fabric. Air permeability, a given area in the vertical direction of the air flow rate, a given time period, is measured by the fabric test area inside the pressure difference of the fabric. Basically, it depends on weight, thickness and porosity of fabric. The porosity of fabric is the demonstration of the air gap as a percentage within fabric. It has been important for especially the tent fabric, parachute fabric, raincoat fabric and garment, the fabric used in air bags, industrial filters and sail cloth. Moreover, when thermal properties of clothing and body interaction are taken into consideration, there has been the effect of air permeability. there is an instrument which is designed to test the air permeability of fabric on the market .it is air permeability tester . Air permeability is an important feature of fabrics (Sundaramoorthy et al., 2011) and is one of the main factors affecting the t...

How To Process The Elmendorf Tear Strength Test

The Elmendorf tear tester has been developed specially for the paper industry and is outstanding for simplicity of operation and high measurement accuracy. The exchangeable pendulum is equipped with a pneumatic sample clamp. The initiation and return of the pendulum, as well as sample cutting is completely automatic. The device is operated via an integrated touch screen, where the test method can be selected, specific settings can be adjusted, and, after the measurement, results and statistics can be  displayed.Each pendulum is supplied with the appropriate control weight so that, with the help of the service program, it can easily be checked for functionality and balance. The Elmendorf tear test Procedure:     Cotton fabric was taken.     Warp and weft direction of the fabric was identified.     Two strips were cut from the fabric in both directions having dimensions of 100 x 63.5 mm.     The sample was then fixed in the jaws of the ...

Classfication Of The Textile Testing

Textile testing is the term for a whole series of tests that examine the physical, mechanical and chemical properties of textiles. These tests are sometimes done before a textile goes into widespread use, or they're done on textiles arriving from other countries for sale in US markets. Countries like the United States have established standards for what should and should not be in textile products. Tests can show whether companies making textiles are in compliance or not. Many textile tests have many types. Some of them are physical tests, in which a sample of textile material is examined closely for feel and appearance. Such tests are done on individual fibers or strands of material and on yarns, threads made of several fibers twisted together. Textiles are subjected to light and other elements to see how they react. Some of these tests are done in a weather-ometer, a machine that tests for weathering and lightfastness of textiles. It's basically an enclosed box. Textiles...
