What is IEC 60335-2-124:2020

The International Electrotechnical Commission (IEC) is an international standardization organization that focuses on the preparation and publication of international standards for electrical, electronic, and related technologies. One of their significant standards is IEC 60335-2-124:2020, which deals with the safety requirements for hand-held and transportable motor-operated electric tools. Let's delve into the details of this technical standard and understand its importance in ensuring user safety.


The scope of IEC 60335-2-124:2020 encompasses hand-held and transportable motor-operated electric tools intended for professional, industrial, and household use. These tools include but are not limited to drills, grinders, saws, and sanders. The standard addresses the potential hazards associated with their use and provides guidelines for manufacturers to ensure the safety of users during operation, maintenance, and servicing.

Risk Assessment and Safety Requirements

Before designing a hand-held or transportable motor-operated electric tool, manufacturers must conduct a thorough risk assessment according to IEC 60335-2-124:2020. This involves identifying potential hazards such as electric shock, thermal and mechanical injuries, and risks related to materials, components, and construction. Based on the risk assessment, safety measures must be implemented to eliminate or minimize these risks, ensuring the safe operation of the tools.

The standard specifies various safety requirements that manufacturers must adhere to. These include measures to prevent electric shocks through insulation, grounding, and protective devices. It also covers protection against mechanical hazards such as blade or disc guards, ergonomic design considerations to prevent fatigue or strain, and methods to reduce noise and vibration levels. Additionally, the standard addresses specific safety requirements for tools used in hazardous environments or when handling potentially explosive materials.

Compliance and Certification

In order to ensure a high level of user safety, manufacturers must comply with the guidelines outlined in IEC 60335-2-124:2020 during the design, production, and testing phases. They must conduct thorough evaluations and tests to verify the compliance of their tools with the standard's safety requirements. Once a tool successfully meets all the requirements, it can be certified as compliant with IEC 60335-2-124:2020 by accredited certification bodies. This certification provides assurance to users that the tool has undergone rigorous safety checks and meets international safety standards.
