FMVSS 302 refers to the combustion test of vehicle interior materials, the full name is Flammability of materials used in the occupant compartments of motor vehicles.

FMVSS302 specifies the fire performance requirements of interior materials for vehicle compartments, and the standard specifies the requirements for the flame retardancy of materials used in passenger compartments of automobiles. The purpose is to reduce deaths and injuries caused by vehicle fires, especially vehicle interior material fires caused by similar matches and cigarette fire sources.
FMVSS302 is suitable for passenger cars, multi-function passenger vehicles, trucks and buses.

Sample request edit Voice
Sample size and quantity: 102mm×356mm×thickness (the thickness of the sample used in the car, but not more than 13mm, if it is greater than 13 mm, it must be cut into 13 mm.) At least 5 samples, if along different directions If there are different burning speeds, at least 5 samples must be sampled 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.

Application
The horizontal flammability tester can detect the relative burning rate and flame retardancy of textiles, especially automotive interior fabrics. Flame retardant properties of automotive interior materials under fault and abnormal conditions.

Features
The tester is composed of a test part and a control part and adopts an integrated design, which is convenient for on-site installation and debugging.
The shell and important parts of the test chamber are made of stainless steel, which is resistant to smoke and gas corrosion. The control system has a high degree of automation and has an automatic ignition function.
Digital display of temperature and time, convenient observation and recording, stable and reliable use

Test requirementsedit

1. The sample does not burn, or the speed of the flame burning horizontally on the sample does not exceed 102mm/min
(Note: When the surface of the sample is cut out, this determination requirement is not applicable to testing the horizontal flame burning speed of the surface);
2. From the start of the test timing, 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 timing starts, it is considered to meet the requirements of FMVSS302.
(Note: The starting position of the time recording is 38mm away from the ignition end, when the fire reaches this position, the time starts to be recorded)
