14、hine Method, Type A 180 peel, strip specimens. Test speed 50 mm/minute. After ageing, the test specimen shall be prepared by making two parallel cuts, using a sharp scalpel blade, through the EPDM veneer into the underlying natural rubber. The cuts are made along the “styling grooves“ for the whole

15、length of the test specimen. If no such grooves are present, the cuts should be made 10 mm apart. The EPDM is separated by hand between the two cuts until the freed end can be clamped in the grips of the testing machine as described in ASTM D 413.
