Standard Test Method for Curling and Twisting on Unwinding of Pressure-Sensitive Tapes

Significance and Use

This test method will provide information on the relative tendency of tapes to curl, twist, or form into a tube with touching edges. The amount of each is a predictor of the difficulty one might experience in handling strips of tape of any length during their application.

There are several causes for variation in the extent or degree of these characteristics and may vary themselves within a production lot of tape. Therefore, it is essential to use an accepted sampling plan (see Section 7) when it is desired to use this test method to compare two types of tape for acceptance sampling purposes.

Scope

1.1 This test method provides one procedure for determining the extent of curling and the degree of twisting resulting from the unwinding of tape from its roll.

1.2 The values stated in either SI or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system must be used independently, without combining values in any way.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
