scope:

Specifies the method to determine the ability of an adhesive tape to resist impact forces. An adhesive tape may possess adequate breaking and tear strengths to withstand a steady force, but it may lack sufficient impact strength to withstand the shock forces sometimes experienced in use. The maximum width of adhesive tape tested by this method is 25 mm. For rolls of adhesive tape of this width or less, the impact resistance measured corresponds to that of adhesive tape as supplied commercially i.e. with factory-cut edges. For rolls of adhesive tape wider than 25 mm, this test method provides for the adhesive tape to be cut down to 25 mm with a well-sharpened instrument. In such cases, because of the better cutting of the edges, the results may be higher than would be found on commercially supplied adhesive tape.
