12、 To demonstrate compliance, the sample size and method of testing shall be in accordance with FLTM BN 024-02. 3.14.2 Performance - Environmental Aging All materials, portions of components, and composites defined by this specification that have not been treated, modified or reformulated and exceed
13、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 environmental aging requirements applicable to the basic material
14、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, regardless of max burn rate, must be evaluated for both perma
15、nency 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. 3.14.3 Flammability Test Program Materials, portions of components, and composites governed by this s
16、pecification must also comply with the requirements of ES-D3AB-11014-AA. 3.15 ESB-M17H144-B FLAMMABILITY REQUIREMENT The burning rate shall be 4 in (101 mm)/min maximum, when tested per FLTM BN 024-02 without the lot sampling plan procedure. In addition, the test specimen shall not exhibit any flashing or sudden flaming on either surface in excess of the above maximum value.
