Product Model : SL-S12
Sharp Edge Tester To determine whether accessible edges on toys are likely to cause injury.
Detailed description

1.35LB Fixed Force Sharp Edge Tester ISO 8124-1 , Children Products / Toys Safety Test Equipment


Application

Used to determine whether the edge of a toy or item is a sharp edge with an unreasonable risk of injury.


Product Information                                                                                               

To determine whether accessible edges on toys are likely to cause injury. A self-adhesive PTFE tape is attached to a mandrel, which is then rotated for a single 360-degree revolution along the accessible edge being tested. If the tape is cut in half or longer in length (approx. 13 mm), the edge is identified as a hazardous sharp edge. Toys intended for use by children under 8 years old are subject to this requirement before or after use & abuse testing.


Test principle

The steel shaft used to simulate children's fingers needs to be hardened. The surface Rockwell hardness should be no less than 40, the surface roughness should not be greater than 0.40 microns, and the diameter should be 9.35 mm ± 0.12 mm. A layer of simulated artificial skin tape was applied perpendicularly to a steel shaft wrapped with simulated artificial skin glue with a force of 6 N (1.35 lb). The steel shaft was constant tangent at 23 mm/sec ± 4 mm/sec. The speed is rotated for one week. Check the edge of the test to cut (cut) the simulated artificial skin adhesive paper. If cut (cut), the tested edge is defined as a potentially dangerous sharp edge.
