The clamp has been tested and approved for:
1) Clamp Pressure – ensuring the earthing clamp is capable of establishing and maintaining low resistance electrical contact with equipment.
2) Electrical Continuity – ensuring the electrical continuity from the teeth throughout the earthing clamp is less than 1 ohm.
3) High Frequency Vibration – ensures the earthing clamp is capable of maintaining positive contact when attached to vibrating equipment.
4) Mechanical Pull Test – ensures the earthing clamp cannot be pulled off the equipment without the intentional application of force.
