TN2018  Sharp Edge Tester

Edge Test Apparatus

INTRODUCTION

It is used to examine toys in normal use and after resonable abuse whether exist or produce the danger of cut,belongs to the toys safety test item.Metal shell is durable. The king-size footswitch makes operation more convenient.

Special photoelectric sensor indicates force value function,to assure the test force fix in 1.35 pounds when testing. Avoiding the indicatrix produces error due to the different perspective.

TEST PRINCIPLE

A self-adhesive tape is attached to a mandrel which is then rotated for a single 360° revolution along accessible edge being tested . The tape is then examined for the length of cut .
