18、-1:2006 4 INTRODUCTION IEC 62395-1 provides the essential requirements and testing appropriate to electrical resistance trace heating equipment used in industrial and commercial applications. While some of this work already exists in national or international standards, this standard has collated mu
19、ch of this existing work and added considerably to it. IEC/TS 62395-2 provides detailed recommendations for the system design, installation and maintenance of electric trace heating systems in industrial and commercial applications. It is the objective of IEC 62395 that, when in normal use, electric
20、al trace heating systems should operate safely under their defined conditions of use, by a) employing heaters of the appropriate construction and meeting the test criteria detailed in Part 1. The construction should include a metallic sheath, braid, screen or equivalent electrically conductive cover
21、ing; b) operating at safe temperatures when designed, installed, and maintained in accordance with Part 2; c) having at least the minimum levels of overcurrent and ground fault protection recommended in Part 2. Some tests of Part 1 differ from similar tests developed by TC 20 and are to be reviewed
22、in the future. These and other tests are almost identical to the tests given in IEC 62086-1:20011 and are duplicated in Part 1 for completeness (see notes in the text). 1 Permission to reproduce the text of several tests from IEC 62086-1:2001 that are not specific to explosive gas atmospheres has be

24、 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 w
