13、s its surface, at a rate of more than 4 in (101 mm) per min. To demonstrate compliance, the sample size and method of testing shall be in accordance with FLTM BN 024-02. 3.11.2 Performance - Environmental Aging All materials, portions of components, and composites defined by this specification that
14、have not been treated, modified or reformulated and exceed a max burn rate of 3.0 in (76 mm) per min as specified by the Flammability Lot Sampling Plan of FLTM BN 024-02, must be evaluated for permanency of the materials flame retardant properties per ESB-M25P3-A according to the accelerated environ
15、mental aging requirements applicable to 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 BN 024-02, re

17、, portions of components, and composites governed by this specification must also comply with the requirements of ES-D3AB-11-14-AA. 3.12 PLANT PROCESSING FLAMMABILITY (FLTM BN 024-01) Shall not support combustion after being exposed to a standard flame for 30 s at a distance of 1 in (25 mm) from the
18、 tip of the needle. 3.13 BONDED ASSEMBLY The criterion for material acceptability shall be the assemblys job performance. This means that the materials composition and formulation must form a satisfactory bond when bonded to itself or to other approved components in the assembly under approved produ
19、ction conditions. 3.13.1 Appearance After Bonding The ultimate use of this material is to provide a heat bonded door panel of pleasing appearance and loft. For this reason, finished panels containing this padding must be visually interchangeable with finished panels containing the material upon whic
20、h approval was originally granted, other conditions being equal. 3.13.2 Resistance to Elevated Temperatures (FLTM BN 113-02) A bonded assembly or test sample prepared as in FLTM BN 113-01, shall show no evidence of loosening or separation of the bonds or loss in loft after exposure.

24、or bonding door panels. It must, therefore, be an electrically clean pad, free of metal particles or other harmful impurities. In the dielectric or radio frequency field there is to be no charring, arcing, or burning of the padding, due to impurities in it. Failure of an average of 1/2 of one percen
25、t of the material to meet this requirement shall be cause for rejection. 3.13.6 Lumpiness Shall contain no lumps, knots, neps or nits of either fiber or resin large enough to result in a lumpy or bumpy or otherwise unsightly appearance in the finished door panel. Such imperfections shall be cause for rejection of the materials.
