試験手順：
1 Fix one end of the needle tube firmly to the jig and adjust the specified span load of test needle  according to table 3 , and select bending angle as following, normal wall 25 °, thin wall 20 ° and ultra thin wall 15 °.
2. Apply a sufficiently large force at the specified span position, exert force bi-directionally 20 times at a frequency of 0.5 Hz to observe the breakage of the needle cannula.
