Abstract: A testing system for a drug delivery device includes a frame member having first and second ends, a driving member positioned near the frame member, a surrogate syringe barrel operably coupled with the frame member, a flange extender adapted to couple with a portion of the surrogate syringe barrel, and a plunger rod adapted to couple with the flange extender and be at least partially disposed within the surrogate syringe barrel while being movable therein. The driving member is movable in an axial direction between the first end and the second end of the frame member. The plunger rod includes first and second ends and a longitudinal length therebetween, the first end being positioned near a portion of the driving member. The driving member measures a maximum urging force exerted on the plunger rod when moving in the axial direction towards the second end of the frame member.
