SCOPE The material defined by these specifications is a laminated, aluminum foil lined, kraft fiberboard of good quality and uniform construction. 2. APPLICATION These specifications were released orig
3、inally for the following materials: ESB-M3E79-A as a thermal barrier and insulator under carpeting and/or other floor cover materials. ESB-M3E79-B as a replacement for asbestos/resin - bonded seat belt anchor insulator ESB-M8G145-A. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS
4、Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 CONSTRUCTION Shall be constructed of a laminated core of kraft and reclaimed fiber plies, sized to reduce water absorption. Laminated to each side of the core shall
5、 be an outer liner of 0.00030 in (8 m) No. 1145-0 grade reflective aluminum foil which is mounted on hard sized kraft paper using casein/neoprene adhesive or equivalent. The aluminum foil liner shall cover both sides of the finished board. 3.3 FINISH (FLTM BI 109-01) Shall be equal to or better than
6、 that of the sample approved for production by the Textile Engineering Section, Body Materials Engineering Department.
