What does Fmvss 302 mean?
Flammability of Interior Materials
302 (FMVSS 302), Flammability of Interior Materials, is used to determine the burn resistance capabilities of materials used in the occupant compartments of motor vehicles. This test is typically performed on materials in passenger cars, trucks, and buses.
What does UL94 HB mean?
Slow horizontal burn test
FEATURES AND BENEFITS of UL 94 Flame Classifications UL 94 V-2 Vertical Burn; Burning stops within 60 seconds, Flaming drips ARE allowed. UL 94 H-B Horizontal Burn; Slow horizontal burn test (H-B) are considered “self-extinguishing”. This is the lowest (least flame retardant) UL94 rating.
What does UL94 v0 mean?
UL 94 is a plastics flammability standard released by the Underwriters Laboratories (USA). The standard classifies plastics according to how they burn in various orientations and part thicknesses from the lowest flame-retardant to most flame-retardant in six different classifications. UL 94 Rating. Definition of Rating.
What is UL94 VTM 0 certified?
UL 94 VTM Rating: VTM-0, VTM-1 and VTM-2 – Thin Material Vertical Burning Testing. This test method is used for thin specimen or materials that are too flexible or may distort, shrink or flex during the traditional vertical testing (failure to pass the UL 94 V test is a precondition of all VTM ratings).
Which government body enforces the Federal Motor Vehicle Safety Standards Fmvss?
The National Highway Traffic Safety Administration (NHSTA) is the federal government agency that issues and enforces FMVSS for motor vehicles and regulated parts that are manufactured domestically or imported into the US.
What is UL94 standard?
UL 94, the Standard for Safety of Flammability of Plastic Materials for Parts in Devices and Appliances testing, is a plastics flammability standard released by Underwriters Laboratories of the United States.
What is V0 fire rating?
V-0 Vertical Burn Burning stops within 10 seconds after two applications of ten seconds each of a flame to a test bar. NO flaming drips are allowed. V-1 Vertical Burn Burning stops within 60 seconds after two applications of ten seconds each of a flame to a test bar. NO flaming drips are allowed.
What VTM 0?
Vertical Testing of Thin Materials (VTM‑0, VTM‑1, VTM‑2) This test is used for materials that are thin, or are too flexible or may distort, shrink or flex during ordinary vertical testing.
How do you test UL94?
The test uses a ½” x 5″ specimen held at one end in a horizontal position with marks at 1″ and 5″ from the free end. A flame is applied to the free end for 30 seconds or until the flame front reaches the 1″ mark (see Fig. 2.1). If combustion continues the duration is timed between the 1″ mark and the 5″ mark.
What is Fmvss certified?
Federal Motor Vehicle Safety Standards (FMVSS) identify mandatory minimum safety performance requirements for motor vehicles and certain motor vehicle equipment in the United States.
What does Fmvss compliant mean?
Federal Motor Vehicle Safety Standards
The Federal Motor Vehicle Safety Standards (FMVSS) are U.S. federal vehicle regulations specifying design, construction, performance, and durability requirements for motor vehicles and regulated automobile safety-related components, systems, and design features.
What is the difference between UL 94 V0 V1 and V2?
UL 94 V-0 Vertical Burn; Burning stops within 10 seconds, NO flaming drips are allowed UL 94 V-1 Vertical Burn; Burning stops within 60 seconds, NO flaming drips are allowed UL 94 V-2 Vertical Burn; Burning stops within 60 seconds, Flaming drips ARE allowed.
What is the FMVSS 302 test?
A new test method was created based on the 1951 Federal Specification CCC-T-191b, Method 5906* “Flame Resistance of Cloth, Horizontal”. The new test method, known as FMVSS No. 302, was adopted in 1971 to establish a maximum burn rate for interior materials.
Where is the FMVSS 302 regulation located?
The FMVSS 302 regulation is located in the Code of Federal Regulations, Title 49 – Transportation, Subtitle B – Other Regulations Relating to Transportation, Chapter V – National Highway Traffic Safety Administration, Department of Transportation, Part 571 – Federal Motor Vehicle Safety Standards.
What is the highest UL94 rating for surface burn?
UL 94-5VA Surface Burn; Burning stops within 60 seconds, test specimens MAY NOT have a burn-through (no hole). This is the highest (most flame retardant) UL94 rating. UL 94 V-2 Vertical Burn; Burning stops within 60 seconds, Flaming drips ARE allowed.
