Be safe with the new range of insulated tools from Gray Tools

Tool preparation

The process begins with modifying the original Gray tool to be insulated in order to meet the ASTM F-1505 standards. The goal is to ensure the tool operator is unable to contact any exposed metal that could potentially be energized during the normal operation of the tool.

Insulation Process

Once the preparation phase is completed each tool moves to the insulation process. Insulating is a multi-step process that meets or exceeds the ASTM F-1505 standards for insulating adhesion, dielectric properties, flammability, and durability. In the final stages the insulated tool is trimmed, cleaned and polished. Most of the steps in the insulating process require a precise and often lengthy amount of curing time to achieve optimum results.

Individual Tool Testing

With insulation the process completed, each tool is then subjected to a series of tests to ensure compliance to ASTM F-1505. The goal of these tests is to insure the adhesiveness of the insulating material under a variety of temperatures and conditions as well as making sure each tool meets or exceeds the dielectric minimums set forth in the specifications. Only after a tool has passed every exhaustive test is it laser engraved with the ASTM F-1505 double triangle symbol and the year the tool was insulated.

Our Goal -100% Protection

Each Gray insulated tool is double insulated to ensure maximum protection for the operator. In addition to providing protection to up 1000V the dual colored insulation also serves as an added visual safety indicator. Under the orange top layer of insulation is a second yellow layer. Should the yellow layer be visible through the outer orange layer the user is immediately alerted that the tool is no longer safe and must be discarded.
