Notes:

Footnote 1

Tensile strength was determined by the grab test described in ASTM D5034-09(2013), "Standard Test Method for Breaking Strength and Elongation of Textile Fabrics (Grab Test)."

Footnote 3

The water ponding test requires that the membrane retain 25.4 mm of water with no passage of water through the membrane for two hours.

Footnote 4

The percentage retention of tensile strength was determined based on the tensile strength determined by the modified grab test of ASTM D5034.
