IEC 60703-1 applies to automatic electrical controls for use in, on, or in association with equipment for household appliances and similar use. IEC 60703-1 applies to:
— the inherent safety of automatic electrical controls, and
— functional safety of automatic electrical controls and safety related systems,
— controls 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.
IEC 60703-1 specifies the requirements for construction, operation and testing of automatic electrical controls used in, on, or in association with equipment.
This document does not:
• apply to automatic electronic controls intended exclusively for industrial process applications unless explicitly mentioned in the relevant part 2 or the equipment standard. However, this document can be applied to evaluate automatic electrical controls intended specifically for industrial applications in cases where no relevant safety standard exists.
• 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 will apply.
• address the integrity of the output signal to the network devices, such as interoperability with other devices unless it has been evaluated as part of the control system.
IEC 60703-1:2022 text has been approved in Europe as EN IEC 60730-1:2024 without any changes. This consolidated version consists of the main text and the amendment, which can also be found separately from the standards history.
