7、ANCE TO ADHESIVE SEEPAGE The material, when tested as described, shall resist penetration or seepage of ESB-M2G43 or ESB-M2G56, Adhesive (Rubber Base), through more than 50% of the thickness of the material. In addition, there shall be no through “spot“ bleeding at any area of the material. Test Met
8、hod . Prepare a 12 x 12 in (300 x 300 mm) x thickness of sample. . Apply 15 - 20 g of ESB-M2G43 and/or ESB-M2G56 adhesive (Rubber Base) on the mid 12 x 12 in (300 x 300 mm) area of a sheet steel panel, spreading uniformly over the surface. The panel used should be 12 x 15 in (300 x 380 mm) or a size
9、 which will permit support of two lengthwise ends over a frame or rack. . Place the sample on the treated surface of the panel, then roll with a roller weighing 5 lb (2.3 kg) (without applying additional pressure). . Turn the panel upside down and rest the ends on a rack, frame, or upturned boards.
10、Allow adhesive to set for 24 h at 23 +/- 2 C. . Determine % seepage. 3.7 HUMIDITY RESISTANCE The material shall not delaminate or disintegrate when cemented to a metal panel and suspended in an inverted position for 5 days at 38 +/- 1 C and 95 - 100% relative humidity. 3.8 COMPRESSION AND RECOVERY (

13、4-B FLAMMABILITY REQUIREMENT 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 its surface, at a rate of more than 4 in (101 mm) per min. To demonstrate compliance, the sample size a
14、nd method of testing shall be in accordance with FLTM BN 024-02. 3.12 PERFORMANCE - 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 spe

Any m
16、aterial, 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, regardless of max burn rate, must be evaluated for both permanency of materials flame retardant properties an
17、d changes in mechanical, chemical and physical properties per ESB-M25P3-A applicable to the basic materials category of this particular specification. 3.13 FLAMMABILITY TEST PROGRAM Materials, portions of components, and composites governed by this specification must also comply with the requirement
18、s of ES-D3AB-11014-AA. 3.14 OBJECTIONABLE CONTAMINANTS (FLTM AN 101-13 A & B) Shall be free from residual asphalt and other contaminants which might cause padding to trim cover material contact stains, bondline, or sewline stains. There shall be no evidence of staining. 3.15 RESISTANCE TO BLEEDING (
19、FLTM AN 101-01) All padding that are dyed shall correspond to rating 5 when compared to the AATCC Chart for measuring transference of color. 3.16 ODOR No disagreeable odor within the temperature range of -18 C to -102 C. Material that is considered to have a disagreeable odor by the Quality Control or Product Engineering Office will be subject to rejection. 3.17 MILDEW RESISTANCE No visual evidence of mildew growth and no mildew odor after 7 days exposure in a humidity cabinet controlled to 100% relative humidity at 38 C.
