14、 And Performance Requirements 4.5.1 Tensile Strength 4.5.1.1 Method To be performed on a constant rate of traverse type tensile machine with specimen clamps of the smooth drum type not less than 13 mm (1/2 in) diameter. The distance between the bite of the clamps at the start of the tests shall be 2
15、54 mm (10 in). Strands of the thread, cut from consecutive positions on the spool, shall be tested individually. The test shall be conducted with the pulling clamp moving at a uniform speed of 305 13 mm per minute (12 1/2 in per minute). If any strand breaks within 13 mm (1/2 in) of the clamps, that
16、 result shall be discarded. The average of the results of 10 satisfactory tests from at least five tubes shall be reported.
