7、 backskin thickness. Test Method: Cut several 12.7 x 75 mm samples from separate areas of the test specimen and examine the cross sectional view of the skin to foam laminate using a measuring magnifier (ex. Bausch & Lombs Measuring Magnifier (7X), Catalog No. 81-34-35 with the system scale No. 81-34
8、-37, or equivalent). Measure the thickness of each component and the total thickness of the laminate at several points along the cut surface of the cross section.
