What is IEC 60745-1 Ed.4:2018?

The International Electrotechnical Commission (IEC) has developed various standards to ensure the safety and performance of electrical equipment. One such standard is IEC 60745-1 Ed.4:2018. This technical article aims to provide an easy-to-understand explanation of this standard and its significance.

Understanding the Scope

IEC 60745-1 Ed.4:2018 is a safety standard specifically targeted at hand-held motor-operated electric tools. It applies to a wide range of tools, including but not limited to drills, sanders, grinders, and saws. The primary purpose of this standard is to minimize potential hazards associated with the use of these tools by providing guidelines for design, construction, and testing.

The standard covers aspects such as electrical safety, mechanical safety, and thermal safety. It sets requirements for insulation, earthing, protective measures against electric shock, and protection against mechanical hazards like moving parts or cutting edges. Additionally, it addresses aspects related to noise reduction, vibration, and ergonomic considerations to improve user comfort and reduce the risk of injury.

The Importance of Compliance

Adherence to IEC 60745-1 Ed.4:2018 is crucial for manufacturers and users of hand-held motor-operated electric tools. By complying with this standard, manufacturers ensure that their products meet specified safety requirements, minimizing the risk of accidents and injuries. Users can have confidence in tools that bear compliance marks indicating adherence to the standard.

Furthermore, compliance with this standard facilitates trade by providing a common framework for safety evaluation and certification globally. Manufacturers can export their tools to different markets without the need for extensive retesting and certification, saving time and resources.


In conclusion, IEC 60745-1 Ed.4:2018 plays a vital role in ensuring the safety of hand-held motor-operated electric tools. It sets forth comprehensive guidelines for electrical, mechanical, and thermal safety aspects of these tools. Compliance with this standard is crucial for manufacturers to meet safety requirements, gain consumer trust, and facilitate global trade of their products. As users, it is essential to be aware of this standard and utilize tools that adhere to its specifications to ensure our own safety.
