Aerosol valve has inner stem and outer stem. Labthink PARAM XLW(PC)Auto Tensile Tester can test the aerosol valve stem pulling-off force. Put the stem in between the upper and lower clamps, and pre-set the tensile speed at 50mm/min. Then, choose tensile resistance testing and start. The strength for aerosol valve to leave the valve body is the pulling-off strength. According to requirements, the final testing results should be statistical values of the maximum value of more than 3 specimens. The inner stem should be no less than 49N, and the outer stem should be no less than 40N.
