A method and apparatus for determining the work required to expel a tampon from a tampon applicator having a barrel containing the tampon and a plunger for expelling the tampon from the barrel. The method includes the steps of selecting and applying an applicator gripping test force to a grip zone on the barrel of the tampon applicator and selecting a tampon expulsion test rate and applying a force to the plunger sufficient to expel the tampon from the barrel of the tampon applicator at the selected tampon expulsion test rate. Further, the method includes the step of calculating the force on the plunger required to expel the tampon from the barrel at the selected tampon expulsion test rate as a function of the distance the tampon travels during expulsion. The apparatus includes a test stand which supports a gripping device having a pair of movable fingers which are adapted to grip the grip zone on the barrel of the tampon applicator at a selected applicator gripping test force, and which also supports an expulsion device having a movable rod to apply a force to the plunger sufficient to expel the tampon from the barrel at a selected tampon expulsion test rate. Additionally, the apparatus includes a sensor associated with the movable rod to measure the force on the plunger required to expel the tampon from the barrel at the selected tampon expulsion test rate as a function of the distance the tampon travels during expulsion to determine the work required to expel the tampon.
