45 Degree Automatic Flammability Tester is mainly used in garment fabric tent fabric, such as decorative fabric flame retardant performance measurement is composed of control system and combustion chamber, the sample is installed in the combustion chamber sample rack, the tilt Angle of 45 fire mouth close to the sample, with the flame returned sample stipulated time, observation sample combustion condition and speed of the spread of flame on the sample, evaluation of ignition and flame spreading performance of the sample.

45 Degree Flammability Tester Testing principle:

1. Combustion intensity and speed test

Under specified conditions, the sample is placed at an Angle of 45 degrees, the sample is ignited for 1s, and the time required for the sample to burn upward with flame for a certain distance is used as a measure to evaluate the intensity of the textile combustion. The fabric with surface flapping is used as an additional indicator for the intensity of combustion.

2.Damage area and length test

Under the specified test conditions, the textile samples were ignited in the direction of 45 degrees, and the after burning and smoldering time, damage area and damage length of the fabric after combustion were measured.

3.Times of touch with flame test

Under the specified test conditions, the textile samples were ignited in the direction of 45 degrees, and the number of times of touch with flame was measured when the fabric was burned 90mm from the lower end of the sample.

GESTER 45 Degree Flammability Tester Operational program:

1.Take a sample holder that has been installed from the dryer, place it on the sample rack in the test instrument, pass the sign line through the guide wire hook of the sample rack plate, and then hang a hammer on the sign line just below the guide wire ring to make it taut.

2.The door is shut off test set the timer to zero, press start button, the timer start time, that the flame is in contact with the specimen surface 1 s when the flame burning to hang on the top of the marker of sample, the heavy hammer falling due to line was burn out, the timer stop timing, accurate records chronograph is shown in the burning time of the specimen to light out of the dryer time should not exceed 45 s.

3. During the test, the combustion condition of the sample should be observed. If the combustion is not complete, then should be observed if there is any sign of carbonization or melting on the back of the sample or not.
