scope:

This part of IEC 62395 specifies requirements for electrical resistance trace heating systems and includes general test requirements. This standard pertains to trace heating systems that may comprise either factory-fabricated or field-assembled (work-site) units, and which may be series heater cables, parallel heater cables, heater pads or heater panels that have been assembled and/or terminated in accordance with the manufacturer's instructions for connection to voltage supplies up to and including 450-750 V. This standard also includes requirements for termination assemblies and control methods used with trace heating systems. This standard does not include or provide for any applications in potentially explosive atmospheres. This standard does not cover induction, impedance or skin effect heating.
