FMVSS **2 Flammability test to Motor Vehicle  Interior materials

Ecosafene have rich experience to provide FMVSS **2 Flammability test to Motor Vehicle  Interior materials.
 
FMVSS **2: Federal Motor Vehicle Safety Standard **2
FMVSS**2 Flammability of Interior materials
 
FMVSS **2 Scope：
This standard specifies burn resistance requirements for materials used in the occupant compartments of motor vehicles

FMVSS **2 Purpose.：

The purpose of this standard is to reduce the deaths and injuries to motor vehicle occupants caused by vehicle fires, especially those originating in the interior of the vehicle from sources such as matches or cigarettes.
 
FMVSS **2 Application：

This standard applies to passenger cars, multipurpose passenger vehicles, trucks, and buses.

FMVSS **2 Test Procedure：

a.       Mount the specimen so that both sides and one end are held by the U-shaped frame, and one end is even with the open end of the frame. Where the maximum available width of a specimen is not more than *1 mm, so that the sides of the specimen cannot be held in the U-shaped frame, place the specimen in position on wire supports as described in S5.1.3, with one end held by the closed end of the U-shaped frame.
b.       Place the mounted specimen in a horizontal position, in the center of the cabinet.
c.       With the flame adjusted according to S5.1.4, position the bunsen burner and specimen so that the center of the burner tip is *9 mm below the center of the bottom edge of the open end of the specimen.
d.       Expose the specimen to the flame for *5 seconds.
e.       Begin timing (without reference to the period of application of the burner flame) when the flame from the burning specimen reaches a point *8 mm from the open end of the specimen.
f.         Measure the time that it takes the flame to progress to a point *8 mm from the clamped end of the specimen. If the flame does not reach the specified end point, time its progress to the point where flaming stops.
g.       Calculate the burn rate from the formula: B = *0 × (D/T)
Where:
B = Burn rate in millimeters per minute
D = Length the flame travels in millimeters, and
T = Time in seconds for the flame to travel D millimeters.
