FMVSS302 Standard Flame Retardant Test of Automotive Interio

Author: Date :2021-05-27 Views: order
The FMVSS302 flame retardant test standard for automotive interior parts specifies the technical requirements and test methods for the horizontal combustion characteristics of automotive interior materials, and is suitable for the evaluation of the horizontal combustion characteristics of automotive interior materials.
 
  Surface material:
   2 meters or specified size
 
  Inner layer material:
Sample size and number: 102×356×thickness (the thickness of the sample used in the car, but not more than 13mm, if it is greater than 13mm, it must be cut into 13mm) at least 5 samples, if there are different burns in different directions Speed, you need to sample at least 5 samples in each direction in different directions. If the size of the material does not meet the requirements of the test, a sample that meets the requirements of the test shall be made.
 
   Judging requirements:
   (1) The sample does not burn, or the horizontal flame speed on the sample does not exceed 102mm/min;
  (2) When the surface of the sample is cut out, this determination requirement is not applicable to test the flame horizontal burning speed of the surface;
  (3) Starting from the time of the test, if the sample burns for less than 60 seconds, it stops burning, and the damage length of the sample does not exceed 51mm from the position where the time is started, it is deemed to meet the requirements of FMVSS302;
  (4) The starting position of the timing is 38mm away from the ignition end. When the fire reaches this position, the timing starts.
