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.

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...

Standard Procedure Of Oxygen Index Test Methods

Oxygen index tester test methods, which describes the tendency of a material to sustain a flame, are widely used as a tool to investigate the flammability of polymers. They provide a convenient, reproducible, means of determining a numerical measure of flammability. A further attraction is that the test method uses inexpensive equipment and only requires a small sample size. These methods have been used to systematical investigate the relative flammabilities of fire-retarded materials, frequently comparing the effectiveness of fire-retardants and fire-retardancy mechanisms. The quintessential feature of oxygen-index methods is that the sample is burnt within a controlled atmosphere. The standard procedure is to ignite the top of the sample, using a gas flame which is withdrawn once ignition has occurred, and to find the lowest oxygen concentration in an upward flowing mixture of nitrogen and oxygen which just supports sustained burning. The criticality criterion typically tak...

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 ...
