The FTT FMVSS 302 is manufactured according to the Federal Motor Vehicle Safety Standard No. Flammability standards of acoustic foam and panels, guidelines and requirements. To address this major threat, the US government worked with the SAE (Society of Automotive Engineers) to develop the standard FMVSS 302. A History of FMVSS 302 The National Highway Traffic Safety Administration (NHTSA) is an American agency that regulates the automotive industry to keep transportation safe for consumers. ... An assembly of upholstered materials is subjected to a match-flame equivalent to examine its burning behavior. google_color_text="5F6A72"; FMVSS 302 is administered by the National Highway Traffic Safety Administration (NHTSA), which regulates safety of all highway vehicles. Scope. 1.Materials shall not burn,nor transmit a flam front across its surface，at a rete of more than 102mm/min. 30141(a)(1)(A), a motor vehicle that was not originally manufactured to conform to all applicable FMVSS shall be refused admission into the United States unless NHTSA has decided, either pursuant to a petition from the manufacturer or registered importer or on its own initiative, (1) that the nonconforming motor vehicle is substantially similar to a motor vehicle of the same model year that was originally manufactured for importation into and sale in the United States and certified by its manufactu… Application. Ä FMVSS 302 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. Automotive: ISO 3795 (FMVSS 302) This international standard specifies a method for determining the horizontal burning rate of materials used in the occupant compartment of road vehicles. The exposed side of the test specimen is subjected to a gas flam from underneath. American FMVSS 302. Because the SAE J369 and the ISO 3795 are technically equivalent testing methods, passing the FMVSS 302:2017 is equivalent to passing the SAE J369 and the ISO 3795. Horizontal Burn (HB Rating)A specimen less than 3 mm thick is tested in a horizontal … Standard : FMVSS 302 Title : Federal Motor Vehicle Safety Standard: Flammability of Interior Materials Description: The test is conducted inside a test chamber where the test specimen is mounted horizontally. Specifies a horizontal burn rate of not more than 102 mm/minute on materials within 13mm of the passenger compartment interior. The standard is based on a recommended practice developed by SAE. S1. Under 49 U.S.C. FMVSS #302 COMPLIANT FMVSS #302 states, "Flammability of Interior Materials - Passenger Cars, Multipurpose Passenger Vehicles, Trucks, and Buses (Effective 9-1-72). Materials used within the passenger compartment need to have a degree of burn resistance so that occupants have time to escape the vehicle in the event of a fire. New trend: Roof Cover Bellow for large CNC machines. OTEGO manufactures fabrics and seam sealing tapes for automotive and multiple other purposes. American FMVSS 302 A flame is applied to a test specimen to determine the burning behavior of a fabric used for the interior of motor vehicles. GENERAL REQUIREMENTS Federal Motor Vehicle Safety Standard (FMVSS) No. The flammability testing was done on finished parts, which included the vinyl and the foam that was laminated to it. • FMVSS No. Samples with a burning time of less than 60 seconds, and a burnt distance of 51 mm or less, similarly fulfill the requirements of this standard irrespective of the burning rate. Motor vehicles contain a number of components that can burn if subjected to a large enough ignition source. Since 1971, the FMVSS 302 has been the standard for any vehicles’ interior to ensure the safety of passengers and reduce fire risks. A glass observation window enables the tester to monitor the progress of any ignition, after the samples have been inserted via a hinged door on the side – samples of material measuring 356mm x 100mm are mounted horizontally in a U-shaped holder, which is slid onto rails within the chamber. When fully inserted, the end of the sample is situated above a Bunsen burner with a 10mm tube diameter, exposing the free end of the material under test to a small natural gas flame. This protocol evaluates the propagation of fire on the sample. A. Federal Motor Vehicle Safety Standards (FMVSS) Guide. Testing is carried out in a small combustion chamber typically 37cm long by 20cm wide and 35cm high, incorporating holes in the floor to allow air ingress and a ventilated clearance at the top. Safety standards such as FMVSS 302 (USA), BS AU 169a and ISO 3795 (all similar standards) have been developed to help reduce deaths and injuries to occupants caused by vehicle fires, especially those originating in the interior of the vehicle from discarded cigarettes and matches. During an aircraft conception, it is necessary to respect numerous standards. The FMVSS 302 specifies the burn resistance requirements for materials used in the occupant compartments of motor vehicles (i.e. The outcomes of the FMVSS 302’s prerequisites are lowering the burn rate of the materials, lowering the severity and the frequency of the burn injuries, and increase the evacuation time for the passengers. The only fire test that any material in the interior of a highway vehicle, including buses, must meet is the fire performance required by the Federal Motor Vehicle Standard No. For general applications a burn rate of no more than 100mm per minute is acceptable, although some vehicle manufacturers have tightened requirements to stipulate slower burn rates. 302.The FMVSS 302 specifies the burn resistance requirements for materials used in the occupant compartments of motor vehicles (i.e. This standard applies to seat belt assemblies for use in passenger cars, multipurpose passenger vehicles, trucks, and buses.. S3. Purpose and scope. In 1969 in the US, within 400 thousand fire vehicles, 25% of them declared to fire departments came from the vehicles’ interior. Guide for vehicle manufacturer's to use in filing out Test Specification Forms. Several test methods have been developed by the motor industry to assess burning behaviour. To be compliant, it needs to stay under 102 mm/minute. Then the propagation speed is measured to calculate the burn rate of the material (B). Measurement of burning time is completed when the flame either extinguishes or completes its travel to the last measuring point. … S1. Engineer must design cars to comply numerous standards. FMVSS 302 Flammability of Interior materials-Test requirement. Among them ABD0031 certifies…, Every year number of fires occur around the globe due to the negligence or the…, 1. //-->. What is RoHS Officially named Directive 2002/95/EC, RoHS is a directive of the European…. OEMs specify ammability testing based on FMVSS 302 and technically equivalent OEM standards. European Flame Testing Standards V (10–1–12 Edition) §571.302 Standard No. Material A has a non-adhering interface with material B and is tested separately. Part of material B is within 13 mm of the occupant compartment air space, and materials B and C adhere at every point of contact; therefore, B and C are tested as a composite. This method permits testing of materials and parts of the vehicle interior equipment individually or in combination up to a thickness of 13mm. In some cases manufacturers have also developed their own specifications based on these standards. Since 1971, the FMVSS 302 has been the standard for any vehicles’ interior to ensure the safety of passengers and reduce fire risks. Standards as of Oct. 1, 2014. If you have a drawing or other documented requirements that call out FMVSS 302 (or the ISO equivalent), you … google_ad_height=600; Note: The equivalent of the FMVSS 302 among the ISO standards is the ISO 3795:1989.
