Standard Test Methods for Mandrel Bend Test of Attached Organic Coatings

Importancia y uso:

4.1 Coatings attached to substrates are elongated when the substrates are dimensionally unstable, or are bent during the manufacture of articles or when the articles are abused in service. These test methods have been useful in rating attached coatings for their ability to resist cracking when elongated. They have been useful in evaluating the flexibility of coatings on flexible substrates. The elongation of coating films may also be tested using Test Method D2370. The correlation between elongation determined in accordance with Test Methods D522/D522M and D2370 is unknown.
