This extended version of the official IEC Standard is available in English only and provides the user with a comprehensive content of the Standard. IEC 60730-2-7:2026 EXV includes the content of the references made to IEC 60730-1:2022. 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
