Flammability tester:
   The flammability tester is a ventilated chamber with a standard ignition tool, a sample frame and an automatic timing device.
This anti-air metal test chamber can prevent the circulation of air around the sample frame and flame but allow natural ventilation to be oxidized rapidly. Small room 368mm(141/2-inch) x depth 216mm(81/2english).
(inch) x height 356mm(14 inches), with a 12 12.7mm(1/2-inch) hole in the back of the upper enclosure, and a ventilation strip at the bottom of the sliding glass door in the front of the small chamber.
   The sample is installed in the frame and placed on the sample rack. The dip Angle is 45. The installation of the sample clip should be able to adjust the thickness between the sample and the front of the flame. There is a pointer, when the sample frame is properly adjusted, it Contact the front of the sample.
   The sample clip is composed of two metal plates with a thickness of 1.6mm(1/16 inch) thick and a clamping device along the second edge. The sample is fixed between the two clamping devices, and the plates are slotted loosely in order to be correct.
Prospective. In addition to the width of 38mm(11/2in), the two plates of the sample holder are covered. The sample clip is supported on the shelf in the small room of the wind proof test with 45 corners, and 5 samples should be prepared Clip.

The design must adjust the sample from the outside of the combustion chamber.
   The ignition tool is driven by the projectile body, which is composed of a gas nozzle with a separate hypodermic needle, and the gas nozzle is protected by a copper cover.
   Stop line from the edge of bobbin tension through the appropriate installation on the framework and small sample room wall cable, allowing the line contains appropriate location, just off the ignition burning collision in the center of the specimen127mm(5in), stop line 50 mercerized sewing thread.
  A heavy hammer is tied to the stop line and when it falls, stop the timer.
  The glass door slides in a slot in the front of the cubicle. The design shall be fixed in the open position to insert the sample holder.
  A sensitive fuel control valve regulates fuel supply in the tank. At one end of the control valve is a 12.7mm(half inch) penis connection, which is connected to a size 4 standard butane gas cylinder with a capacity of 0.9kg(2 lb).
  The pressure gauge is a u-shaped glass tube with a gas line on it to record the gas pressure sent to the micro-burner.
  The design shall be able to facilitate the control of the test, such as the control of energy control and start-up test. The actuator moves the micro burner to the front position and automatically starts the timer when the flame hits the sample.When the line is burned and the hammer falls, stop the timer.
 
Brushing Device
  The bristle device is a set of floor board, which is dragging a small car, which runs on the parallel track of the second side of the lower surface of the bottom plate. The brush is hinged to the back of the base plate and is vertically 150g(0.33lbs).The pressure is added to the car.
  The brush is arranged in two rows of hard nylon bristles, with a diameter of 0.41mm(0.016 inches) and a length of 19mm(3/4 inches). Each tuft of hard hair has 20 nylon bristles, 4 clusters per inch.There is a clamp on the front of the car, which can be used to clamp the sample on the car.
  Hold the sample in the car with clamps, lift the brush, push the car to the rear, place the brush on the sample surface, and then use the hand to pull the car forward at a uniform speed.
