ABSTRACT:
A torque measurement device is described which facilitates the testing of a handset cap of a public telephone for determining compliance with evolving mechanical disassembly requirements. The device is an interface between the handset cap under test and the torque measurement tool for uniform application of torque to the handset cap and the acquisition of reliable and reproducible test results. The device is a metallic receptacle having in its base a cylindrical aperture which conforms dimensionally to the shape of the handset cap and lodges the handset cap during testing. Also, the device includes set screws which bear against the cap to hold it uniformly in place during testing.
