Fray Resistance
1/ Test specimen shall be full width and 3 feet in length.
2/ When splices are tested for breaking strength, the splice shall be centered between the jaws.
3/ Test with hook side up.
4/ Stiffness (bending moment) shall be conducted in accordance with ASTM D 747 except as
follows:
a. Unless otherwise specified, the testing conditions shall be in accordance with ASTM
D 1776.
b. The test specimen shall be a rectangle of cloth of dimensions two (2) by one (1) inches
with the long dimension parallel to the fabric direction under test, warp or filling, as
applicable.
c. The load scale reading shall be recorded only at the specimen angular deflection of 60
degrees.
d. The stiffness is the bending moment of specimen at a deflection angle of 60 degrees and
shall be calculated to three significant figures as follows:
Bending moment, inch -lb. = Load scale reading X moment weight*
