IEC 60730-2-24:2026 PDF

IEC 60730-2-24:2026 applies to automatic displacement electrical controls - for use in, on, or in association with appliances for household and similar use; NOTE 1 Through this document, the word "control" means "displacement electrical control". EXAMPLE 1 Displacement electrical controls used in electrical pressure cookers with gross volume up to 25 l, with working pressure over 4 kPa and less than 150 kPa. - that are AC or DC powered controls with a rated voltage not exceeding 690 V AC or 600 V DC; - used in, on, or in association with equipment that use electricity; - that are mechanically or electrically operated, responsive to change of position of point of action. NOTE 2 Requirements for manual switches not forming part of an automatic control are covered in IEC 61058‑1‑1. This document applies to - inherent safety of automatic electro-mechanical displacement electrical controls; - functional safety of automatic electro-mechanical displacement electrical controls; - the operating values, operating times, and operating sequences where such are associated with equipment safety; - displacement electrical controls having temperature sensing element(s), in which cases additional requirements can be considered to be necessary. Requirements for temperature sensing controls are included in IEC 60730-2-9. This document specifies the requirements for construction, operation and testing of automatic displacement electrical controls used in, on, or in association with equipment. This document does not - apply to automatic electronic controls; - take into account the response value of an automatic action of a control, if such a response value is dependent upon the method of mounting the control in the equipment. Where a response value is of significant purpose for the protection of the user, or surroundings, the value defined in the appropriate equipment standard or as determined by the manufacturer applies. NOTE 3 For more information about guidance to the application of displacement electrical controls, see Annex AA. This part 2-24 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 may be given to future editions of, or amendments to, IEC 60730‑1. This part 2-24 supplements or modifies the corresponding clauses in IEC 60730-1, so as to convert that publication into the IEC standard: Particular requirements for displacement electrical controls. Where this part 2-24 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 2-24 indicates that the relevant clause or subclause applies.
