      <title>The Effectiveness of the Suppression of Low Frequency Acoustic Resonances with Porous Sound Absorbing Structures of Multifunctional Upholstery Materials of Car Body Interior</title>
      <link>https://trid.trb.org/View/1459295</link>
      <description><![CDATA[The article presents the results of research on the effectiveness of the technical method of suppression of low frequency acoustic resonances occurring in the air volumes of passenger and luggage areas of the car body by increasing the absorption degree of sound wave energy by multifunctional panel and volumetric elements of a car body interior. The research reviews a sliding shutter and integral carpeting of a luggage compartment, rear wheel arch trim, backrest upholstery and car door trim as the modified multifunctional elements of the car body interior. The results of experimental research show that putting the modified multifunctional car body interior upholstery, characterized by high sound absorbing properties, into the studied prototype of a car allows to reach the effect of reduction of the overall sound levels up to 9 dBA on the mode of intensive acceleration movement and sound pressure levels, which are registered at a frequency of the second motor harmonic of the engine 2n / 60 - 16 dB.]]></description>

      <title>TRANSIT FLAMMABILITY REQUIREMENTS</title>
      <link>https://trid.trb.org/View/28693</link>
      <description><![CDATA[Control of the flammability characteristics of furnishings within a structure will reduce the fire hazard to the structure and enhance the life safety of its occupants. Flammability of materials should be considered along with comfort, cost and wear. Quantifying flammability, setting acceptable standards, identifying appropriate test procedures, and locating the material to satisfy the standards are steps taken by the Port Authority of New York and New Jersey.]]></description>

      <title>REPORT OF FIRE TEST ON AN AM GENERAL METRO BUS</title>
      <link>https://trid.trb.org/View/28662</link>
      <description><![CDATA[A study of the fire safety of a bus supplied by the Washington, D.C. Metropolitan Transit Authority was conducted. The objectives of the work were: (1) to determine the minimum ignition from source necessary to initiate a fire in the bus, and (2) to determine the means by which a fire, once started, is most likely to grow and spread. A series of small-scale laboratory tests were run in addition to the three full-scale tests. Tests showed that accidental ignition by a cigarette or dropped match in unlikely. However, the seat can be ignited with one or two matches, if applied at the proper location, as by an arsonist. In full-scale tests, ignition of the seat occurs readily with the following ignition sources: (1) a small bag of paper trash on the seat, (2) a newspaper under the seat, or (3) if the contents of a can of lighter fluid is poured on the seat. Fire growth and spread in the bus is primarily through involvement of the seat cushioning. Fire spreads from seat to seat with little direct involvement of other interior materials. In all three tests, between one or two minutes after the urethane ignited, dense smoke filled the bus space seriously reducing visibility. Spread of fire beyond the seat of origin is not necessary for the level of smoke to be formed.]]></description>
