ASTM D3813/D3813M-2020Standard Test Method for Crimping, Twisting, and Tubing of Pressure Sensitive Tape When Unrolled

Kahulugan at paggamit
5.1 This test method will provide information on the relative tendency of the tape to curl, twist or form a tube with a contact edge. The amount of each material can indicate the difficulties one may have in handling strips of any length during use.

5.2 There are several reasons why the degree or extent of these characteristics can change and may change in a batch of tape. Kaya nga, when you need to use this test method to compare two types of tapes for sampling purposes, you need to use the accepted sampling plan (see Section 7).

Hakbang 1: Saklaw
1.1 This test method provides a procedure for determining the degree of crimp, the degree of distortion, and the tendency of the tube to form after loosening the tape from the tape roll.
