Sharp Edge Tester used to determine that metal or glass edges on toys and other articles intended for use by children under 8 years of age, and such edges exposed in normal use or as a result of reasonably forseeable damage or abuse of such toys and articles, present a potential risk of injury by laceration or avulsion. Standards: UL 3300 EN 71-1 ASTM F963 16CFR 1500 ISO 8124-1 GB 6675-2

• The especially powerful value photoelectricity induction instruction function guarantees the test strength value fixed in 1.35 pounds all long, and avoid the errors caused by different angle observation.
• The especially powerful value external adjustment function, may extremely conveniently adjust the actual strength value to be consistent with the demonstration value, guarantee strength value calibration accuracy.
• With 1.35 pounds calibration device, it can calibrate and adjust test force value at any time.
• Test shaft is made of steel and hardened processing. The surface should be smooth. The max force vertically applied to the axis when testing should be 1.35 LB.
• Test shaft in its 75% turn routine, the tangent speed is 1.00±0.08 inches per second.
• The test tape is pressure-sensitive PTFE (TFE) high temperature electrical insulation tape.

• The especially powerful value photoelectricity induction instruction function guarantees the test strength value fixed in 1.35 pounds all long, and avoid the errors caused by different angle observation.
• The especially powerful value external adjustment function, may extremely conveniently adjust the actual strength value to be consistent with the demonstration value, guarantee strength value calibration accuracy.

• Thickness of adhesive tape on sharp edge: 0.066-0.099mm
• Width of adhesive tape on sharp edge: no less than 6mm
• Cylindrical shaft: d=9.53mm
• Charger: I/P 12A 50HZ 220V 25W O/P 15V 1.5A

• Test environment: under Greenhouse condition
• This equipment is portable; place it on even area when using.

Place it under standard temperature 20-25℃ with relative humidity 20-70% for at least 4h.

1. Check if it can run normally with its amount of electricity before test
   1. Turn on the power (Fig 2) and then press handle switch (Fig 1)
   2. (C) panel switch (Fig 1) (E) foot switch (Fig 1)

   Keep 90±5° between axial lead and the toy edge, exert force on axis, when pilot light of force value is on and the red indication line meets requirement of 1.35LBS.

2. Wrap a layer of PTFE adhesive tape anticlockwise at the end of axis; overlay of adhesive tape end <0.1 cun [a unit of length (=1/3 decimeter)]
3. Support the toy edge right in the middle of PTFE adhesive tape and keep 90±5° with axial lead until pilot light of force value is on; press the starting switch or handle switch and step on the foot switch; make axis rotate a circle; then remove PTFE adhesive tape of sharp edge and observe it. If its cut length >12.7mm, then there is sharp edge and perform the next test.
4. Unplug the power cable (fig 2) as well as equipment's when test finishes to avoid wastage of current.
