34、 and commercial applications. While some of this work already exists in national or international standards, this standard has collated much of this existing work and added considerably to it. IEC 62395-2 provides detailed recommendations for the system design, installation and maintenance of electr
35、ic trace heating systems in industrial and commercial applications. It is the objective of IEC 62395 that, when in normal use, electrical trace heating systems operate safely under their defined conditions of use, by a) employing heaters of the appropriate construction and meeting the test criteria
36、detailed in IEC 62395-1. The construction includes a metallic sheath, braid, screen or equivalent electrically conductive covering; b) operating at safe temperatures when designed, installed, and maintained in accordance with IEC 62395-2. c) having at least the minimum levels of overcurrent and eart
37、h-fault protection required in IEC 62395-1 and IEC 62395-2. BS EN 62395-1:201362395-1 IEC:2013 7 ELECTRICAL RESISTANCE TRACE HEATING SYSTEMS FOR INDUSTRIAL AND COMMERCIAL APPLICATIONS Part 1: General and testing requirements 1 Scope This part of IEC 62395 specifies requirements for electrical resist
38、ance 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 and parallel trace heaters or surface heaters (heater pads and heater panels) t
39、hat have been assembled and/or terminated in accordance with the manufacturers instructions. This standard also includes requirements for termination assemblies and control methods used with trace heating systems. This standard provides the essential requirements and testing appropriate to electrica
40、l resistance trace heating equipment used in industrial and commercial applications. The products certified according to this standard are intended to be installed by persons who are suitably trained in the techniques required and that only trained personnel carry out especially critical work, such
41、as the installation of connections and terminations. Installations are intended to be carried out under the supervision of a qualified person who has undergone supplementary training in electric trace heating systems. This standard does not include or provide for any applications in potentially expl
42、osive atmospheres. This standard does not cover induction, impedance or skin effect heating. Trace heating systems can be grouped into different types of applications and the different conditions found during and after installation necessitate different requirements for testing. Trace heating system
43、s are usually certified for a specific type of installation or application. Typical applications for the different types of installation include, but are not limited to: a) installations of trace heating for surface heating on pipes, vessels and associated equipment applications include: freeze prot
44、ection and temperature maintenance; hot water lines; oil and chemical lines; sprinkler system mains and supply piping; b) outdoor exposed area installations of trace heating applications include: roof de-icing; gutter and down-spout de-icing; catch basins and drains; rail heating2; 2Further evaluati
45、on may be required to address application specific conditions such as fluctuations in impressed voltage and voltage spikes. BS EN 62395-1:2013 8 62395-1 IEC:2013 c) installation with embedded trace heating applications include: snow melting; frost heave protection; floor warming; energy storage syst
46、ems; door frames; d) installations of trace heating internal to conduit and piping applications include: snow melting in conduit; frost heave protection in conduit; floor warming in conduit; energy storage systems in conduit; internal trace heating for freeze protection of potable water lines; enclo
