This Recommendation applies to newly manufactured maximum demand indicators Class 1.0 intended to operate as attachments to watthour meters or varhour meters, coupled mechanically thereto and to indicate the maximum of average power, active or reactive, measured during successive equal intervals of time and to their type tests. It applies to the meters only as regards mutual effects between the maximum demand indicators and the meter. Maximum demand indicators of the same class may be attached to watthour meters or varhour meters of different accuracy class. This Recommendation does not apply to maximum demand indicators based on thermal effects, or those operated by impulses, nor to cumulative indicators, intended only for control purposes. The requirements for meters without maximum demand indicators are covered by specific Recommendations — I EC Publication 43, Recommendations for Class 2.0 Alternating Current Watthour Meters; I E C Publication 170, Class 1.0 Alternating Current Watthour Meters; and IEC Publication 145, Class 3.0 Var-hour (reactive energy) Meters. Recommendations for class 0.5 watthour meters are under consideration.

The present recommendations apply only to newly manufactured induction type var-hour meters for the measurement of reactive energy of frequency between 40 and 60 Hz (c/s), of an accuracy class of 3.0 for ordinary usage and to their type tests. They do not apply to special types of var-hour meters except multi-rate meters. They do not apply to instrument transformers, even when used in conjunction with the meters covered by these recommendations.

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.
