SCOPE The material defined by these specifications is a sealed and painted ESB-M2E66 type pressed wood panelboard of good quality and uniform composition. 2. APPLICATION These specifications were released orig

3、inally for material used for applications requiring superior dimensional stability, moderate formability and rigidity. 3. REQUIREMENTS In addition to the requirements listed herein, the finished assembly shall conform to ESB-M15P6-A. 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppli

4、ers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 APPEARANCE (FLTM BI 109-01) The color, pattern, and finish shall match the approved Design Center master sample or shall be as specified on the engineering drawing. 3.3 CONSTRUCTI

5、ON (SAE J 947) The board shall be a single ply fiberboard constructed of a homogeneous mixture of wood fibers bonded under heat and pressure with natural and synthetic resins. The fiberboard shall be completely sealed on surface and edges with a moisture barrier coating of approximately 34 g/m2. ENG
