8、gether with a thermoplastic binder. The thermoplastic binder shall also act as part of the bonding agent when the door panel is heat bonded. The binder must be 65 +/- 5% of the total weight of the pad. This binder shall consist of a thermoplastic resin or a polyblend of resins compatible with the bo
9、nding grade cover materials and the approved bonding quality sub-foundation or foundation boards employed. Test 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 sample
10、s in a large tared weighing bottle. . Oven dry at 102 +/- 3 C until a constant weight is obtained. Record final 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 st

14、rformance - Environmental Aging All materials, portions of components, and composites defined by this specification 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
15、evaluated for permanency of the materials flame retardant properties per ESB-M25P3-A according to the accelerated environmental aging requirements applicable to the basic material category of this particular specification. Any material, portions of components, and composites defined by this specific
16、ation that have been treated, modified or reformulated to conform to Flammability Lot Sampling Plan of FLTM BN 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-
17、A applicable to the basic materials category of this particular specification. 3.6.3 Flammability Test Programs Materials, portions of components, and composites governed by this specification must also comply with the requirements of ES-D3AB-11014-AA. 3.7 TENSILE STRENGTH, min (ASTM D 1682, Grab Te

19、13, using water) 1/4 in (6 mm) 3.11 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 app
20、roved production conditions. ENGINEERING MATERIAL SPECIFICATIONESB-M17H132-A ESB-M17H132-B Printed copies are uncontrolled Copyright 2006, Ford Global Technologies, LLC Page 4 of 4 3.11.1 Appearance After Bonding The ultimate use of this material is to provide a heat bonded door panel of pleasing ap
21、pearance 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. 3.11.2 Resistance to Elevated Temperatures (FLTM BN 113-02) A bonded ass
22、embly 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. 3.11.3 Objectionable Contaminants (FLTM AN 101-03) Shall be free from residual asphalt and other contaminants which might cause padding to trim cover mat
23、erial contact stains, bondline, or sewline stains. There shall be no evidence of staining. 3.11.4 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) 3.11.5 Electrical Properties This material is to be used in a dielectric field for bonding door
24、 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 present in it. Failure of an average of 1/2 of one percent of th
25、e material to meet this requirement shall be cause for rejection. 3.11.6 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 material. 3.11.7 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.
