45° Flammability Test

> 45° flammability test
45° flammability test and vertical flammability test will be applied to components which were used for hold and baggage. The ignition resource of 45° flammability test is same to that of horizontal flammability test. The test will be carried out in a small chamber without ventilation and 3 results will be record.

> 45° flammability test
Method
Forty five degree test. A minimum of three specimens must be tested and the results averaged. The specimens must be supported at an angle of 45° to a horizontal surface. The exposed surface when installed in the aircraft must be face down for the test. The specimens must be exposed to a Bunsen or Tirrill burner with a nominal3/8-inch 1.D. tube adjusted to give a flame of 1 1/2inches in height. The minimum flame temperature measured by a calibrated thermocouple pyrometer in the center of the flame must be 1550 °F. Suitable precautions must be taken to avoid drafts. The flame must be applied for 30 seconds with one-third contacting the material at the center of the specimen and then removed. Flame time, glow time, and whether the flame penetrates (passes through) the specimen must be recorded.
