12、 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 and method of testing shall be in accordance with FLTM BN 24-2. 3.15 PERFORMANCE - ENVIRONMENTAL AGING All materials, portions of components, and composit
13、es 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 24-2, must be evaluated for permanency of the materials flame retardant properties per ESB-M25P3-A
14、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 specification that have been treated, modified or reformulated to conform to Flammability Lot
15、 Sampling Plan of FLTM BN 24-2, 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. 3.16 FLA
16、MMABILITY TEST PROGRAM Materials, portions of components, and composites governed by this specification must also comply with the requirements of ES-D3AB-11014-AA. 5. GENERAL INFORMATION The information given below is provided for clarification and assistance in meeting the requirements of this spec
17、ification. Based on production experience, the ESB-M2G33-A PVC adhesive when applied 85 - 130 g/sq m, dry weight, (specified by uses) and ESB-M2G79-A PVDC when applied approximately 300 g/sq m, dry weight, has been found to produce satisfactory bonds. The type of adhesive and adhesive weight used on the fiberboard, however, will vary depending upon application method, bond design and the materials being bonded. Therefore, the adhesive and adhesive weight should be agreed upon between the supplier and Manufacturing Engineering (Utica Trim Plant, etc.).
