12、3.2.6.2 ESK-M99G143-B (FLTM EU-BN 024-02) Burn Rate, max 100 mm/minute 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 demons
13、trate compliance, the sample size and method of testing shall be in accordance with FLTM EU-BN 024-02. 3.2.6.2.1 Performance-Environmental Ageing Requirements All materials, portions of components, and composites defined by this specification that have not been treated, modified or reformulated, and
14、 exceed a maximum burn rate of 75 mm per minute as specified by the Flammability Lot Sampling Plan of FLTM EU-BN 024-02, 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 t
15、o the basic material category of this particular specification. 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 024-02, regardless of maximum burn rate, must
16、 be evaluated for both permanency of materials flame retardant properties and changes in mechanical, chemical and physical properties per SK-M99P9500-A, Table 1 applicable to the basic material category of this particular specification. 5. GENERAL INFORMATION The information given below is provided
