Attachment Performance Test of Retro-reflective Sheeting

Take the 150 mm * 25 mm retro-reflective sheeting, and remove the 100 mm release paper from one end, and then paste it to the aluminum alloy plate with the thickness 2 mm according to the user’s manual of manufacturers, to manufacture the sample for the attachment performance test.


Place the sample under the standard test condition for 24 hrs, hang the sample horizontally, and make the retro-reflective sheeting downward, and then hang the object with the weight 0.8kg (including the weight of the jig) on the jig at the free end of the retro-reflective sheet, so that the object is 900 with the sample plate. Measure the stripped length L of the retro-reflective sheeting after 5 min.
