JWG 34 is a Technical Committee within the International Electrotechnical Commission (IEC). It is named "TC 27/JWG 34". This committee has published 4 standards.
JWG 34 develops IEC standards in the area of Information technology. Currently, there are 4 published standards from this technical committee.
The International Electrotechnical Commission (IEC) is the world's leading organization for the preparation and publication of international standards for electrical, electronic, and related technologies. Founded in 1906, the IEC provides a global platform for companies, industries, and governments to meet, discuss, and develop the international standards they require.
A Technical Committee (TC) in IEC is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
IEC/IEEE 62395-2:2024 provides detailed recommendations for the system design, installation, maintenance and repair of electrical resistance trace heating systems in industrial and commercial applications. This document does not include or provide for any applications in potentially explosive atmospheres.
This standard cancels and replaces IEC 62395-2:2013. This edition constitutes a technical revision.
This standard includes the following significant technical changes with respect to IEC 62395-2:2013:
a) Design considerations for trace heating on sprinkler systems have been expanded and a figure has been added to illustrate how to avoid undue shadowing of spray patterns from insulated sprigs close to sprinkler heads;
b) Specific details of design considerations for trace heating for emergency eyewash units and safety showers have been added.
This document is published as an IEC/IEEE Dual Logo standard.
