vertical flame test chamber

 The Vertical Flammability Chamber, designed for American Standards, measures the vertical flame spread for children's sleepwear, fabrics, other textile materials or resilient filling materials used in upholstered furniture.

 
Application:
The vertical burning of textiles is suitable for all types of fabrics and their products. Test method applicable to the burning performance of the bottom edge of the vertical textile specified in GB5455-2014 standard.
 
Features:
Gas pipeline system special designed, low space occupied, and convenience to move;
Exhaust vents at the bottom and top of test chamber ensure good ventilation and steady flame;
LED displayer shows the igniting time, afterflame time and afterglow time, with high working efficient and the data more accuracy;
A stainless steel construction, large glass-viewing window;
Excellent reliability and minimum maintenance;
Purpose-designed test chamber.
 
Standards: 
ASTM D6413, CALIF TB117, DOC-FF 3/71, 16CFR Parts1615/1616, FTMS 191-5903, CPAI 84

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 ...

Comparative analysis of water-cooled and air-cooled xenon lamp aging tester

Xenon lamp aging test chamber is the core component of using the box full sunlight spectrum xenon lamp tube simulation, under different environmental conditions to simulate the material aging law, through the experimental results to evaluate weather resistance of materials and products. This paper focuses on the comparative analysis of the advantages and characteristics of the water-cooled and air-cooled xenon lamp aging testing machine. Air-cooled xenon lamp aging test machine : A circular wind is used to cool the heat-trapping xenon lamp tube. Air-cooled xenon lamp tubes used in air-cooled xenon lamp aging test box, generally a typhoon cold xenon lamp aging test chamber is equipped with three air-cooled xenon lamp tubes, and table 1 air-cooled xenon lamp weather-resistant chamber equipped with xenon lamp tubes. The power of the air-cooled xenon lamp tube is generally 1.8kw, and the length of the lamp tube is 340mm compared with that of the water-cooled xenon lamp. The diameter of...

Correct Use Of Color Assessment Cabinet

Observation Angle: The following points are all the facilities required for the Color Assessment Cabinet , and the viewing Angle will directly affect the evaluation results. According to international standards, there are only two observable angles that can be used. They are: A, zero light source and 45 degrees observation (0 °, 45 °), the light from zero (vertical) incident Angle on the sample, sample watchers from 45 degrees. B, light source and 45 ° inclined channel 45 degrees of light source, zero observation (0 °, 45 °), the layout must use specific 45 degrees of inclined (45 ° Fixed Angle table) making from 45 degrees of light source on the samples, sample watchers from zero (vertical). The location of the 45 ° light samples: Regardless of any of the above observation methods, it is important to note that the test sample is placed in the middle of the light box as far as possible to reduce the influence of the external light source. In addition, the most important thing...
