The twisting action which progressively moves along the belt to the free end has enough snap to cause failure of weak links. After the test, the belt shall be insp

Subsequent to the test, inspectio

28、 itself until belt is completely reversed. This procedure shall then be repeated after the belt has been reversed to assure full motion of the belt when flexed from either side and in either direction. 5.1.6.2.3.2 A minimum of twenty five (25) cartridges per belt shall be used for this test. If pack
29、ing instructions require belts of greater length, the connecting links used to lengthen the belts shall be flexed after assembling in both directions to assure free hinging. 5.1.6.2.3.3 A “frozen“ M17 link detected by means of this flexibility test is critical and shall be cause for rejection of lot
