1 Scope
This document specifies the electrical requirements and testing for electrically insulating helmets that
provide electrical insulating protection of head of the worker against electric shock used for when working
live or near to live parts on installations not exceeding 17 000 V AC or 1 500 V DC.
The products designed and manufactured according to this document contribute to the safety of the users
provided they are used by skilled persons, in accordance with EN 50110-1:2023 and/or National
Regulations.
This document does not cover arc flash or additional helmet accessories such as face shields, ear
defenders, lamps and voltage detectors and doesn’t cover mechanical requirements and tests.
