Understanding A Fogging Test Chamber

       Fogging Test Chamber  ,To determine the fogging characteristics of automotive interior trim of textiles, plastic or leather. Fogging is the residue deposited on interior glass of chemicals released from materials under specific temperature conditions. 


     The sample is heated in the fogging tester fog cup and begins to evaporate, and the volatilized gas is condensed on a glass or aluminum foil that has been cooled by the cooling chamber.


    After the completion of the condensation process, the glass plate or aluminum foil was removed. Atomization and volatilization characteristics of the sample were obtained by measuring the atomization value or weight of the condensing component of the glass plate or aluminum foil and compared with the data before being condensed.

     Gloss method:The sample is condensed in the fog cup by the vaporized gas condensed on the low temperature glass plate. The gloss value of the sample can be obtained by comparing and calculating the gloss value before and after the condensation of the glass plate.

    Haze method:The sample was condensed in the fog cup by the vaporized gas condensed on the low temperature glass plate, and the haze value of the sample was obtained by comparing and calculating the haze value before and after the condensation of the glass plate. (Optional)


Weight method:The sample is heated in the fog cup by the vaporized gas condensed on the low temperature aluminum foil, and the weight of the sample atomization-coagulation can be obtained by weighing the weight of the aluminum foil before and after condensation.

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 ...
