Navigating the safety maze
Neil Wooldridge, new equipment technical director at Toshiba Carrier UK explores the diff erences between the IEC 60335 and EN378 standards and sheds light on their scopes, objectives and key requirements.
I
n today’s world, we are surrounded by an array of electronic appliances and systems that make our lives more comfortable, effi cient, and convenient. Behind the
scenes, however, these devices undergo rigorous testing and adhere to a complex set of safety standards to ensure they do not pose harm to consumers or the environment. Two prominent safety standards that play a pivotal role in
this regard are the IEC 60335 and EN378 standards. While both aim to safeguard consumers and the environment, they address distinct facets of safety and carry unique requirements.
IEC 60335: Ensuring the safety of electrical appliances The International Electrotechnical Commission (IEC) 60335
series of standards is a comprehensive set of regulations that focus on the safety of household and similar electrical appliances. These standards, developed by a global consortium of experts, provide manufacturers with

guidelines to design and produce safe, reliable, and energy- effi cient electrical appliances. IEC 60335 encompasses a wide range of products, including but not limited to washing machines, electrical heat pumps, refrigerators, air- conditioners and dehumidifi ers. The primary scope of IEC 60335 standards is to ensure the safety of end-users, prevent electrical and mechanical hazards, and minimise the risk of fi re or injury caused by electrical appliances. The standards are designed to establish a baseline level of safety for these products and are applicable to manufacturers worldwide.
Key Requirements:
Electrical Safety: IEC 60335 prescribes strict guidelines for electrical safety, including insulation requirements, earthing, and protection against electrical shock. It also addresses issues related to power cords, plugs, and connectors to minimise the risk of electrical accidents.
