Procedure

Impact Test

For impact studies, the top block is leveled with the plug removed exposing a 1.43 cm (0.563 in) hole. The 1.27 cm (0.50 in) diameter, round-nosed end of the 4 lb weight may now be dropped from any height along the graduated scale on the guide tube from 0 to 160 inch-pounds.

Bend Test

To make a bend test, the coated panel 3” x 4” (0.048” thickness) is first bent 180° over the 1/8” rod. The bent panel is placed between the parts of the hinge. Then the impact tool, flat face down, is dropped from any desired height onto the upper part of the hinge. The cylindrical fold in the panel is squeezed into a conical shape.
