27、0 IEC:2013 5 INTRODUCTION It is the objective of this standard that, when in accordance with the standard, electrical trace heating systems operate safely under their normal defined conditions of use, by a) employing heaters of the appropriate construction and meeting the test criteria detailed in I

28、EC 62395-1; 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 ground-fault protection, and an evenly distributed electrically conductive metallic braid, sheath or other equivalent electr

29、ically conductive material, as specified in IEC 62395-1 and IEC 62395-2. BS EN 60519-10:2013 6 60519-10 IEC:2013 SAFETY IN ELECTROHEATING INSTALLATIONS Part 10: Particular requirements for electrical resistance trace heating systems for industrial and commercial applications 1 Scope and object This

30、clause of Part 1 is replaced by the following. Replacement: This part of IEC 60519 provides safety requirements for electrical resistance trace heating systems used in industrial and commercial applications for piping, vessels, roofs, concrete slab heating and other similar applications. This standa

31、rd pertains to trace heating systems that may comprise either factory fabricated or field (work-site) assembled 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 manufacturers instructions.

32、 Typical applications include but are not limited to the freeze protection of pipes, tanks and vessels, including fire water systems; maintaining required temperatures of equipment, including pipes, tanks and vessels; earth thermal storage; hot water temperature maintenance; snow melting of surfaces

33、; de-icing of roofs and gutters. This standard does not include or provide for any requirements in potentially explosive atmospheres. This part of IEC 60519 does not cover induction, impedance or skin effect heating. NOTE Specific requirements and test criteria for electrical resistance trace heatin

34、g systems and design, installation, and maintenance requirements for these systems are detailed in IEC 62395-1 and IEC 62395-2. This standard provides general safety requirements for the installation, operation, maintenance and repair of systems and individual circuits and for trace heating systems

35、designs. These safety considerations concern the protection of persons and the environment against dangers of electrical origin and also against certain dangers of non-electrical origin, common to all types of equipment and installations. 2 Normative references This clause of Part 1 is applicable, e
