The PV was reissued in slightly revised form after the Group reported a need for this document. Previous Issues First issue: 02/1972 Last change: 12/1996 1 Scope This standard defines the test of the burning behavior of materials for vehicle interiors that fall un- der US regulation 571.302. If an increase in the combustion speed is seen based on the composition of the flame-retardant vehicle interior trim materials or the form of application of the flame-retardant additives with artificial aging using hot, humid climate, light, cold or cleaning materials, it will be necessary to add aging procedures to this testing specification. 2 Designation Example in the TL: Burning behavior acc. to TL 1010 per US regulation 571.302 (if required in drawing and/or release) Note: For materials for which aging has no recognizable effect on the burning behavior, based on the corresponding experience, the remark “Test after aging per PV 3904 not required” should be added to the affected drawing and/or TL after the requirement "Burning Behavior per TL 1010". 3 Test 3.1 Test Apparatus Mechanical circulation oven ( 80 ± 2 )° C Th e En gl ish tr an sl at io n is be lie ve d to be a cc u ra te .

Direction of the fastest combustion speed. 3.2.1.2 Aging Before the combustibility test, the following must be done: 7 days aging in dry heat (80 ± 2)° C followed by 48 h aging at (23 ± 2)° C and (50 ± 5) % relative humidity. 3.2.2 Testing the Sub-Padding and the Visible Cover Materials in the Assembly 3.2.2.1 Sampling Standard production or appropriately simulated assembly. Dimensions: approx. 50 x 100 mm long on edge and max. 13 mm thick. 3.2.2.2 Aging 7 days aging in dry heat (80 ± 2)° C. 4 Referenced Standards US Regulation 571.302 German Regulation No. 302, Combustibility of Materials for Vehicle Inte- riors
