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

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.
