Abstract

A testing device for testing the mechanical integrity of a hollow breakable item includes a squeezable element to radially abut with a sidewall portion of the breakable item. The testing device further includes a sleeve extending in an axial direction to receive the sidewall portion of the breakable item and having a first contact surface to axially engage with the squeezable element. The testing device also includes a plunger displaceable in axial direction relative to the sleeve and having a second contact surface to axially engage with the squeezable element. The squeezable element is axially squeezable by a relative displacement of plunger and sleeve to increase the squeezable element's radial expansion and to apply radially directed pressure to the breakable item's sidewall portion.
