ASTM D5683-95(1999)e1

Standard Test Method for Flexibility of Roofing and Waterproofing Materials and Membranes

SCOPE
1.1 This test method measures the flexibility of roofing or waterproofing sheet materials or membranes by bending the test material over a block containing arcs of specific radii at a standard temperature.  
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
