It shall also act as part of the bonding agent when t

8、he door panel is heat bonded. The minimum binder weight must be 60% of the total weight of the pad. It shall consist of a thermoplastic resin for a polyblend of resins compatible with the bonding grade cover materials and the approved bonding quality sub-foundation or foundation boards employed. Tes

9、t Method: . Take three 4 x 4 in (100 x 100 mm) samples, one from the center and one from each side, across the roll. . Finely chop samples using a blender or equivalent method. . Place samples in a large tared weighing bottle. . Oven dry at 102 +/- 3 C until a constant weight is obtained. Record fin

10、al sample weight as (W1). . Transfer sample to a beaker and add methyl isobutyl ketone. (Temperature 23 +/- 2 C). Use a minimum of 15 weights of solvent to one of padding. . Allow sample to stand for 24 h. Stir occasionally. . Filter solution twice through a #80 screen mesh filter or equivalent meth

11、od. . Oven dry at 102 +/- 3 C to a constant weight. Record final weight as (W2). . % Binder = (W1 - W2) x 100 - W1 3.4 THICKNESS 0.45 +/- .05 in (FLTM BN 114-01) (11.4 +/- 1.3 mm) 3.5 WEIGHT, min 9.0 oz/yd2(FLTM BN 106-01) (0.305 kg/m2) 3.6 TENSILE STRENGTH, min (ASTM D 1682, Grab Test Method) WMD 1

14、n shall not exhibit any flashing or sudden flaming on either surface in excess of the above maximum value. 3.11 ESB-M17H138-B FLAMMABILITY 3.11.1 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

15、 flame across 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 specifi

16、cation that 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 acceler

17、ated environmental 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 B

18、N 024-02, regardless of max burn rate, must be evaluated for both permanency of materials flame retardant properties and changes in mechanical, chemical and physical properties per ESB-M25P3-A applicable to the basic materials category of this particular specification. 3.11.3 Flammability Test Progr

19、am Materials, portions of components, and composites governed by this specification must also comply with the requirements of ES-D3AB-11014-AA.

20、 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 tip of the needle. 3.13 BONDED ASSEMBLY The criterion for material acceptability shall be the assemblys job performance. This means tha

21、t the materials composition and formulation must form a satisfactory bond when bonded to itself or to other approved components in the assembly under approved production conditions. 3.13.1 Appearance After Bonding The ultimate use of this material is to provide a heat bonded door panel of pleasing a

22、ppearance and loft. For this reason, finished panels containing this padding must be visually interchangeable with finished panels containing the material upon which approval was originally granted, other conditions being equal. 3.13.2 Resistance to Elevated Temperatures (FLTM BN 113-02) A bonded as

23、sembly 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. 3.13.3 Objectionable Contaminants (FLTM AN 101-03) Shall be free from residual asphalt and other contaminants which might cause padding to trim cover ma

24、terial contact stains, bondline, or sewline stains. There shall be no evidence of staining. 3.13.4 Bond Strength, min (FLTM BN 113-01) Original 16 oz (4.5 N) Aged 12 oz (3.3 N) Water immersed 12 oz (3.3 N) 3.13.5 Electrical Properties This material is to be used in a dielectric field for bonding doo

25、r 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 percent of the mater

26、ial to meet this requirement shall be cause for rejection. 3.13.6 Lumpiness Shall contain no lumps, knots, neps or nits or 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.
