An introduction to the pass/fail low-temperature bend test for fabrics coated with rubber or rubber-like materials.
Watch the explainer
What the result means
ASTM D2136 evaluates whether a coated fabric withstands a prescribed bend at an established low temperature. Rubber-coated fabrics become stiffer as temperature decreases.
Scope and limits
The result may help predict use only where deformation conditions are similar to the test. It does not necessarily identify the lowest service temperature. This is buyer education, not a laboratory procedure.
