Important Safety Information

Important Safety Information


Clydesdale can supply a range of Insulated Hand Tools designed, tested and approved / certified to Industry, National and European Standards. This range of tools offers 6 key safety characteristics;

  1. A white shell is moulded onto the metal parts of the tool. This insulating shell is both unbreakable and irremovable, and ensures, instantaneously and permanently, total insulation of the tool.
  2. The orange coloured PVC which covers the shell coated tool is totally irremovable, non-flammable and ensures a perfect grip of the tool when held.
  3. Coating the handles with ridge marks ensures a perfect grip of the tool when held with greasy hands or gloves.
  4. The two finger stop (or Buffers) (where used) are made from treated Rilsan, which has insulation properties in excess of 15,000 Volts.
  5. The end of the handles are reinforced with several layers of PVC onto the shell, in order to withstand the highest of impacts.
  6. All insulating properties are guaranteed for temperatures from -20°C to +60°C (-4°F to 140°F).

Insulated Hand Tools

The exceptional quality of this range of Insulated Tools ensures their use over many years.Every Insulated Tool within this range undergoes 7 separate tests prior to the end of the manufacturing process thus allowing us to offer a full guarantee on each and every tool. The range of Insulated Hand Tools complies with the current version of the following standards;

  • EN 60900
  • ESI 26-3
  • VDE 0680
  • NFC 18-400


Most important to European users is the EN 60900 Standard which gives the tool a rating of 1000V recognised by the double triangle symbol. The tool must pass the following rigourous requirements:

  • Ambient Temp Impact Test - Tool must be dropped from a height of 2m and show no sign of break, tear or crack.
  • Low Temp Impact Test - Tool is cooled to -25degC and must be dropped from 0.6m and show no sign of break, tear or crack.
  • Dielectric Test - 10kV is applied between conductive and insulating components for 3min. Leakage current must be less tham 1mA per 200mm.
  • Penetration Test - A weight of 20N is applied to the must vulnerable part of the tool while it is tested to 5kV for 3min. There must be no perforation or flashover.
  • Insulation Adherence Test - At 70°C, a weight of 500N is applied for 3min to test the adherence of the insulation to conductive component. There must be no tearing or detachment greater than 3mm.
  • Flame Propagation Test - The tool is exposed to flame for 10sec. The resulting flame should not exceed 120mm in the 20 second observation time.
  • Individual Dielectric Testing - Each and every tool must be individually tested to 10kV for 10 sec without flashover and visually checked.
