DELTA 3.1.6.2 SK-M4D9792-B (FLTM EU-BN 24-2) Burn Rate, max 100 mm/minute Note to Flammability: The flammability shall be determined on 100 x 355 mm specimens with a thicknes

13、s of 1.8 - 2.0 mm and smooth surface. In order to comply with Federal Motor Vehicle Safety Standard No. 302, the materials, portions of components, and composites shall not burn or transmit a flame across their surface, at a rate of more than 100 mm/minute. To demonstrate compliance, the sample size

14、 and method of testing shall be in accordance with FLTM EU-BN 24-2. 3.1.6.2.1 Performance - Environmental Ageing Requirement All materials, portions of components, and composites defined by this specification that have not been treated, modified or reformulated, and exceed a maximum burn rate of 75

15、mm per m as specified by the Flammability Lot Sampling Plan of FLTM EU-BN 24-2, must be evaluated for permanency of the materials flame retardant properties per SK-M99P9500-A, Table 1 according to the accelerated environmental ageing requirements applicable to the basic material category of this par

16、ticular specification. ENGINEERING MATERIAL SPECIFICATION SJ-M4D9792-A SJ-M4D9792-B WP 3948-b Page 4 of 7 Any material, portions of components, and composites defined by this specification that have been treated, modified or reformulated to conform to Flammability Lot Sampling Plan of FLTM EU-BN 24-
