1/
One determination shall be made from each sample unit and the results reported as "pass" or "fail". Visual
inspection of the delivered fabric compared to manufacturer's standard product shall be determined.
2/
For the Type I and IA cloth, clamps with flat-grip type jaws may be used. For Type II cloth, the yarn shall be
tested using a constant rate of extension (CRE) tensile testing machine set with a 10 ± 0.05 inch gage length and
operated at 5 inches per minute speed. The yarn shall be tested at 1.5 turns per inch twist for Types I, IA and II
cloth, 1.5 turns per inch for Type IV cloth, 2.8 turns per inch Z twist for Type III, and 3.3 turns per inch twist for
Type V cloth. Twist may be added or removed as appropriate, but care must be taken to handle the yarn in such a
manner that the twist does not deviate from the required twist level per inch prior to closing the jaws of the clamps
on the specimen.
3/
Documentation shall be provided for all Classes stating the finish or lack of finish present.
