IEC 60364-7-753:2014 applies to embedded electric heating systems for surface heating. It also applies to electric heating systems for de-icing or frost prevention or similar applications. Both indoor and outdoor systems are covered. Heating systems for industrial and commercial applications complying with relevant parts of IEC 60519, IEC 62395 and IEC 60079 are not covered. This second edition cancels and replaces the first edition published in 2005 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- the title has been changed from "Floor and ceiling heating systems" to "Heating cables and embedded heating systems" to align with the revised scope;
- the scope has been extended and now covers embedded electric heating systems for surface heating, also electric heating systems for de-icing or frost prevention or similar applications, and covers both indoor and outdoor systems. This includes heating systems for: walls, ceiling, floors, roofs, drainpipes, gutters, pipes, stairs, roadways, non-hardened compacted areas (e.g. football fields, lawns);
- for wall heating systems, this standard contains additional requirements (e.g. metal sheath/enclosure/grid) to protect against the effects of overheating caused by a short-circuit between live conductors due to penetration of an embedded heating unit;
- from heating units delivered from the manufacturer without exposed-conductive-parts, this standard requires a metallic mesh grid covering. This has been reduced to 3 mm for wall heating systems;
- this standard now requires that electric heating systems shall be selected and erected so as to avoid any harmful influence between the heating system and any electrical or non-electrical installations envisaged;
- and this standard covers surface temperatures and now refers the reader to the appropriate IEC guide. -
Technical committeeTypeAcronymIEC 60364-7-740CommitteePublished year2000KeywordsDescription
Specifies the minimum electrical installation requirements to facilitate the safe design, installation and operation of mobile, temporarily or permanently installed electrical machines and structures which incorporate electrical equipment. The machines and structures are intended to be installed repeatedly, without loss of safety, temporarily or permanently, at fairgrounds, amusement parks, circuses or any other places. Defines the electrical installation requirements for such structures and machines, both being either integral parts or constituting the total amusement device. Does not apply to the electrical equipment of machines (see IEC 60204-1).
