Hand tools for live working up to 1000 V a.c. and 1500 V d.c.

This document establishes specific safety requirements for handheld tools designed for live working on electrical systems operating at alternating current voltages up to 1000 volts and direct current voltages up to 1500 volts. It defines the essential constructional criteria, testing methods, and marking conventions necessary to ensure that such equipment provides adequate insulation and mechanical strength for personnel performing tasks on energized conductors. The specifications address various aspects including the material properties of insulating components, the design of handles and grips, and the overall electrical resistance needed to prevent current leakage or accidental contact during operation. Compliance with these technical guidelines is crucial for minimizing the risks associated with electric shock and arc flash incidents in low-voltage environments. The standard covers the full lifecycle of the tool, from its initial manufacturing requirements to ongoing inspection protocols that verify its continued safe performance in the field. By adhering to these defined parameters, manufacturers and users can ensure that tools meet globally recognized benchmarks for electrical isolation and physical durability in live work scenarios.
