ZL-3110 Sharp Edge Tester

Application:

Used to determine whether the edges of toys or items have sharp edges that pose an unreasonable risk of injury.

Compliant with Standards:

ASTM F963 4.8, EN71-1998 8.14, GB6675-2003 A.5.9, 16CFR 1500.48

Power Supply:

220AC/50Hz, Built in rechargeable battery

Usage:

1. Roll a circle of TFE adhesive paper around the edge tester head, with an overlap size not exceeding 0.1 inches (0.25mm).
2. The fixed sample position cannot move or bend the tested edge.
3. When the position of the edge of the assembled toy is not sufficient for experimentation, the sample should be dismantled for testing. However, if dismantling will affect its hardness, other objects can be used to make it hard, but its supporting area cannot be larger than the tested object.
4. The angle between the tester and the testing edge is 90 °± 5 °.
5. The contact point between the edge of the tested object and the adhesive tape should be approximately in the middle of the adhesive tape schedule.
6. The tested object should be tested in its most unfavorable position.
7. Adjust the force of the edge tester to 1.35 LBS (6N).
8. Apply force upwards at the position of the adhesive tape to turn on the indicator light, and the force on the test edge is 1.35 LBS.
9. Turn on the switch of the edge tester to rotate its shaft once.
10. Be careful not to enlarge the cut size of the adhesive tape, measure the cut length with a steel ruler.
11. If the cut length exceeds 0.5in (12.5mm), the test edge end is a sharp edge.

Usage and Understanding:

1. Attach PTFE adhesive tape to the core shaft as required, then rotate the core shaft 360 ° along the touchable edge being tested, and check whether the test adhesive tape is subjected to gravity to determine if the ball can completely pass through the test template. The length of the cut. Calculate the percentage of cut adhesive paper length. If 50% of the adhesive tape is torn, the edge is considered a sharp edge.
2. The edge to be tested should be the touchable edge determined after the touchability test of the toy part or component.
3. If the touchable edges of the toy as a whole cannot be tested, the touchable edges can be disassembled and tested separately while simulating the toy as a whole.

4.The key to sharp edge testing is how to fix the detected edge and ensure that the core axis is at a right angle to the edge, and there is no relative motion between the core axis and the edge during testing.

5.During the rotation of the core shaft, it should be ensured that the pressure applied to the core shaft is continuously stable.
