The particular requirements of this part of IEC 60364 apply to: - sauna cabins erected on site, e.g. in a location or in a room; - the room where the sauna heater is, or the sauna heating appliances are installed. In this case the whole room is considered as the sauna. They do not apply to prefabricated sauna cabins complying with a relevant equipment standard. Where facilities like cold water basins or showers, etc. are installed, the requirements of Part 7-701 also apply. The main technical changes with respect to the previous edition concern the updating of requirements to take into account the evolution in sauna equipment, with particular emphasis on prefabricated cabins. In addition, in response to a need from installers, there has been some elaboration on temperature repartition in saunas as well as protection against electric shock. Finally, the four zones described in the first edition have now been reduced to three zones.

IEC 60364-5-56:2018 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.
IEC 60364-5-56:2018 covers general requirements for safety services, selection and erection of electrical supply systems for safety services and electrical safety sources. Standby electrical supply systems are outside the scope of this part. This part does not apply to installations in hazardous areas (BE3), for which requirements are given in IEC 60079-14. This third edition cancels and replaces the second edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
1) Modifications to normative references and terms and definitions.
2) Under electrical circuits for safety services, addition of requirements concerning circuit and overcurrent protection in order to maintain reliability of safety service power supplies under fire conditions.
3) Under electrical circuits for safety services, addition of requirements stating that circuits for safety services are not to be protected by RCDs or AFDDs.
4) Under emergency lighting applications, addition of requirements to prevent emergency lighting systems being adversely affected by any control system.
5) Addition of requirements for all emergency luminaires in the area to provide full design light output in the event of any final circuit failure.
6) Addition of a new Annex D (informative): Fire switch.
7) Addition of a new Annex E (informative): Example of installation methods of safety services with cable management system.
8) Addition of a new Annex F (informative): Wiring systems.
9) Addition of a new Annex G (informative): Guidance on suitable locations for electrical sources for safety services. -

IEC 60364-4-43:2008 provides requirements for the protection of live conductors from the effects of overcurrents. IEC 60364-4-43:2008 describes how live conductors are protected by one or more devices for the automatic disconnection of the supply in the event of overload (Clause 433) and short-circuit (Clause 434) except in cases where the overcurrent is limited in accordance with Clause 436 or where the conditions described in 433.3 (omission of devices for protection against overload) or 434.3 (omission of devices for protection against short-circuit) are met. Coordination of overload protection and short-circuit protection is also covered (Clause 435). This third edition cancels and replaces the second edition, published in 2001, and constitutes a technical revision. The main changes with respect to the previous edition are:
- Introduction of new informative Annexes B, C and D.
- Information concerning flexible cables added to Scope.
- Requirements added for overload detection for the neutral conductor for harmonic currents.
- Requirement that devices for protection against short-circuit current be capable of making as well as breaking short-circuit current added.
- Information added to clarify protection against overload current.
- Requirements where devices for protection against overload need not be provided expanded.
- Requirements where devices for protection against short-circuit need not be provided expanded.
- Requirements for short-circuit current ratings of busbar trunking systems added. The contents of the corrigendum of October 2008 have been included in this copy. -
