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

Scope

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.
