Semnificație și utilizare
5.1 Această metodă de testare va oferi informații despre tendința relativă a benzii de a se ondula, 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. Prin urmare, 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 (vezi Sectiunea 7).
