11、 TO ADHESIVE SEEPAGE, Initial approval only Shall resist penetration or seepage of ESB-M2G55-A, Water Dispersion, Rubber Base Adhesive, and/or ESB-M2G149-A, High Heat Resistant Adhesive, through more than 25% of the original material thickness. In addition, there shall be no through “spot“ bleeding

12、in any area of the material. Test Method: Prepare a 305 x 305 mm X thickness of sample. Apply 15-20 g of ESB-M12G55-A or ESB-M12G149-A on the middle 305 x 305 mm of a 305 x 381 mm phosphate coated and primed steel panel. Place the sample on the treated surface of the panel, then roll with a 305 mm r

13、oller weighing 2.3 kg without applying additional pressure. Turn the panel upside down and rest the pad on 3 equally spaced rods. Each rod will have a 13 mm diameter and be securely fastened to a 305 x 305 mm masonite board. Place the assembly in a mechanical convection oven, maintained at 102 +/- 2

14、 C. Load the test panel with sufficient weight to compress the pad 50% over each of the three rods. The weight must be evenly distributed to give uniform compression. Examine the assembly for seepage after a 24 h period in the oven. 3.8 AIR FLOW RESISTANCE No evidence of fiber separation and/or dela

15、mination of the material when the surface that faces the engine compartment is tested as follows: Test Method: Direct a blast of air at approximately 45 to the center section of representative 930 cm2 of the material. Test in one direction, then repeat the test on the same spot with the sample turne

16、d 180. The air nozzle shall have an opening of 2.16 - 2.29 mm with a 656 +/- kPa air pressure, and shall be held 100 mm from the center of the test sample. The air blast shall be maintained for 20 s in each direction. 3.9 QUALITY A finished part shall be uniform in color and have a non-fuzzy surface

17、. The exposed surface shall be relatively free of white caps and shall be able to withstand the air erosion requirements established by the affected product engineering office. The part shall be free of uncured areas and binder spots and there shall be no cracks or shingling effect on the finished s

18、kin surface. 3.10 HEAT TRANSFER, Initial approval only (SAE J1361) Procedure “C“, except use a constant steel plate temperature of 175 C. Use 13 mm thickness glass fiber batt.
