Newson Gale’s 2 pole static grounding clamps are FM approved and certified for use within ATEX zones and North American classified areas. In order to meet and exceed these requirements the grounding clamps must be capable of passing a range of stringent tests.
Testing Standards required for ATEX certification & Global FM approval:
Electrical Continuity Testing:
ensures the continuity from the tip throughout the clamp is less than 1 ohm.
Clamp Pressure and Mechanical Strength Testing:
ensures the clamp is capable of establishing and maintaining low resistance electrical contact with equipment.
High Frequency Vibration Testing:
ensures the clamp is capable of maintaining positive contact when attached to vibrating equipment.
Sources of Mechanical Sparking:
ensures no mechanical sparking sources are present in the clamp.
Benefits of using our FM approved clamps:
The powerful combination of sharpened tungsten carbide tips supported by a positive spring mechanism ensures coatings, product deposits or corrosion does not prevent the clamp from connecting directly to the equipment to be grounded.
FM approved 2 pole clamps are designed to be easy to grip and open aiding operators engaged in making repetitive daily grounding connections.
Long Term Value:
Additional value is provided by the corrosion resistant and mechanically robust stainless steel construction of FM approved 2 pole clamps which helps reduce long term replacement costs that are typical of lower quality grounding clamps.
