Sharp Edge Tester and Torque Test Kit

Sharp Edge Tester (KFG-2079)

The Sharp Edge Tester is used to determine whether accessible edges on child-related products are likely to cause injury before or after use or abuse. It is applicable to child-related products for children of no more than ninety-six months. A self-adhesive PTFE tape is attached onto the mandrel which is then rotated for a single 360°revolution along the accessible edge to test and applies 1.35lbs on the accessible edge. If the tape is cut in half or longer in length (approx. 0.5inch), the edge is identified as a hazardous sharp edge.
