13、rial shall show no change in color tone or evidence of spotting and it shall be equal or better than the sample originally approved by Materials Engineering. 3.18 SURFACE FIBER DETERIORATION (SAE J1885) 488.8 kJ/m No excessive deterioration of fibers or yarns after the above Xenon Arc exposure. The
14、resistance to deterioration of approved production material shall be equal to or better than that exhibited by the fabric proposal approved by the Materials Engineering Activity. 3.18.1 Tape Test Test Method: Firmly apply a piece of 3Ms Highland Brand 6200 permanent Mending Tape or 3Ms Scotch Magic
15、Tape 810 (only for South America) to the surface of the exposed fabric (yarn). Then rapidly strip the tape and mount it on a sheet of light or dark cardstock which contrasts with the color of the fiber. Repeat the test with a new piece of tape on the unexposed sample and compare the length and quant
16、ity of fibers removed by the tape. Report fiber deterioration if a significantly larger number of fiber (usually shorter lengths) are removed from the exposed versus unexposed sample. 3.18.2 Abrasion 1000 cycles (SAE J1530A, 500 g load, H-10 wheels, if required, back with S-36 mounting cards or equivalent) In addition, the material shall exhibit no evidence of penetration to the foundation of the pile fibers in the abraded area.
