9.2.1 Cut each specimen either 35 mm (1.5 in.) or 25 mm (1
in.) plus 20 yarns, whichever is wider, by at least 150 mm (6
in.) long (Note 7). The long dimension should be accurately
parallel to the direction of testing and force application.
NOTE 7—The length of the specimen depends on the type of clamps
being used. The specimen should be long enough to extend through the
clamps and project at least 10 mm (0.5 in.) at each end. The specimen
length may be calculated using Eq 1or Eq 2:
