IEC 62395-2:2013 provides detailed recommendations for the system design, installation, maintenance and repair of electrical resistance trace heating systems in industrial and commercial applications. This standard does not include or provide for any applications in potentially explosive atmospheres. This standard cancels and replaces IEC\/TS 62395-2:2008. This standard includes the following significant technical changes with respect to IEC\/TS 62395-2:2008: – This document has been changed from a Technical Specification to an International Standard. – 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; – Specific details of design considerations for trace heating for emergency eyewash units and safety showers have been added.<\/p>\n
