Load required to break (pull apart) fabric
In some installations the insulation material must "bridge" over a discontinuity in its support. The Breaking Load is the force necessary to create structural failure in a "bridging" condition. Insulation with higher Flexural Strength maintain their structural integrity under more rigorous bridging conditions. ASTM C203 is the test method for breaking load and flexural properties of block-type thermal insulation. Dyplast ISO-C1 products have excellent breaking load characteristics. See Flexural Strength.
The maximum stress needed to rupture a fiber, yarn or fabric in a tension test.
