As the International Chair of IEC TC78 Live Working Committee, I am excited to announce the recent publication of the second edition of IEC Standard 61482-2 Live working – Protective clothing against the thermal hazards of an electric arc – Part 2: Requirements.
This revised standard is applicable to protective clothing used in work where there is the risk of exposure to an electric arc hazard.

- New requirements for the thermal stability of the intermediate layers
- Additional material requirement for volume resistance
- New test procedure for the thermal resistance of sewing threads
