IEC 60730-2-24 Ed. 1.0 b:2026

Automatic electrical controls - Part 2-24: Particular requirements for displacement electrical controls

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.
