What is the difference between IEC 60335 and 60730 ?

IEC 60335 and IEC 60730 are two of the most important international standards that relate to the safety of electrical appliances. While both standards are essential for ensuring the safety of users, they focus on different aspects of electrical technology.

IEC 60335 is specifically concerned with the safety of household appliances, such as refrigerators, washing machines, and vacuum cleaners. It sets out to ensure that these appliances are safe for use, with minimal risk of electrical shock or other injuries. The standard defines the minimum requirements for electrical safety, including the detection of fault conditions, temperature control, time functions, and other electrical control mechanisms.

In contrast, IEC 60730 is focused on the proper functioning of automatic electrical controls. It applies to devices that incorporate such controls, including air conditioning systems, electric motors, and electronic sensors. The standard specifies the minimum requirements for these controls to prevent malfunctions, protect users from harm, and regulate the performance of electrical systems.

The main difference between the two standards is their scope. IEC 60335 covers a wide range of consumer appliances, while IEC 60730 applies to devices that require automatic electrical controls.

Understanding the dissimilarities between IEC 60335 and IEC 60730 is crucial for manufacturers, as it helps them ensure that their products meet the necessary safety standards. Adhering to the requirements of one standard does not automatically mean that a product is safe for use. Both standards must be met to ensure the safety of the end user.
