WG 5 - TC 72/WG 5

IEC 60730-2-7:2026 applies to timers and time switches:
- for use in, on, or in association with equipment for household appliance and similar use;
NOTE 1 Throughout this document, the word "equipment" means "appliance and equipment" and "controls" means "timer or time switches".
NOTE 2 Throughout this document, the word "timers" means timers and time switches, unless the type is specifically mentioned.
- for building automation within the scope of ISO 16484 series and IEC 63044 series (HBES/BACS);
- or equipment that is used by the public, such as equipment intended to be used in shops, offices, hospitals, farms and commercial and industrial applications;
- that are smart enabled controls;
- that are AC or DC powered controls with a rated voltage not exceeding 690 V AC or 600 V DC;
- utilized as part of a control system or controls which are mechanically integral with multifunctional controls having non-electrical outputs;
- as well as manual controls when such are electrically and/or mechanically integral with automatic controls.
NOTE 3 Requirements for manually actuated mechanical switches not forming part of an automatic control are contained in IEC 61058-1-1.
This document applies to
- the inherent safety of timers and time switches, and
- functional safety of timers and time switches and safety related systems,
- timers and time switches where the performance (for example the effect of EMC phenomena) of the product can impair the overall safety and performance of the controlled system,
- the operating values, operating times, and operating sequences where such are associated with equipment safety,
- timers for appliances within the scope of IEC 60335 series.
- manual controls when such are electrically and/or mechanically integral with timers.
This document specifies the requirements for construction, operation and testing of timers and time switches used in, on, or in association with an equipment.
This document does not
- apply to time-delay switches (TDS) within the scope of IEC 60669-2-3;
- include devices which only indicate time or passage of time;
- apply to multi-functional controls having an integrated timing function which is not capable of being tested as a separate timing device.
This fourth edition cancels and replaces the third edition published in 2015. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
adoption of IEC 60730-1:2022 (Ed.6.0) with all of its significant changes to IEC 60730 1:2010 (Ed.4).
This part 2-7 is intended to be used in conjunction with IEC 60730-1. It was established on the basis of the sixth edition of that standard (2022). Consideration can be given to future editions of, or amendments to, IEC 60730 1.
This part 2-7 supplements or modifies the corresponding clauses in IEC 60730-1, so as to convert that publication into the IEC standard: Particular requirements for timers and time switches.
Where this part 2-7 states "addition", "modification" or "replacement", the relevant requirement, test specification or explanatory matter in part 1 should be adapted accordingly.
Where no change is necessary, part 2-7 indicates that the relevant clause or subclause applies

IEC 60730-2-7:2015 applies to timers and time switches for household and similar use that may use electricity, gas, oil, solid fuel, solar thermal energy, etc. or a combination thereof, including heating, air conditioning and similar applications. This standard is also applicable to individual timers utilized as part of a control system or timers which are mechanically integral with multifunctional controls having non-electrical outputs. This standard does not apply to time-delay switches (TDS) within the scope of IEC 60669-2-3. This standard applies to the inherent safety, to the operating characteristics where such are associated with equipment protection and to the testing of timers used in appliances and other apparatus, electrical and non-electrical, for household and similar purposes, but also extended to industrial purposes when no dedicated product standards exist, such as that for central heating, air conditioning, process heating, etc. Timers for equipment not intended for normal household use, but which nevertheless may be used by the public, such as equipment intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard. This third edition cancels and replaces the second edition published in 2008. This third edition constitutes a technical revision. This new edition revises the compliance criteria of type 1.S and 2.S action, revises the requirements for filament lamp loads, adds requirements for abnormal operation in Annex H, removes some special requirements for single countries as well as updates the standard to IEC 60730-1:2010, fourth edition. Key words: Timers, Time Switches
This publication is to be read in conjunction with IEC 60730-1:2013.

IEC 60730-2-7:2008 applies to timers and time switches for household and similar use that may use electricity, gas, oil, solid fuel, solar thermal energy, etc. or a combination thereof, including heating, air conditioning and similar applications. This second edition cancels and replaces the first edition published in 1990 and its Amendment 1 (1994). This second edition constitutes a technical revision. This new edition incorporates requirements for tungsten filament lamp loadings as well as updates the standard to IEC 60730-1:1999, Amendment 2 (2007). This Part 2-7 is to be used in conjunction with IEC 60730-1. It was established on the basis of the third edition of that standard (1999) and its Amendment 1 (2003) and Amendment 2 (2007). Consideration may be given to future editions of, or amendments to, IEC 60730-1.
