What is EN 60745-2-4:2003?

EN 60745-2-4:2003 is a technical standard used in the manufacturing and testing of handheld motor-operated electric tools. It specifies safety requirements for angle grinders, which are commonly used in construction, metalworking, and other industries. This standard sets guidelines to ensure that these tools are safe to use and don't cause harm to the operator or others in the vicinity.

Scope and Purpose

The scope of EN 60745-2-4:2003 covers handheld angle grinders with a rated capacity not exceeding 230 mm. The standard outlines requirements related to design, construction, and materials used. It also addresses aspects such as electrical insulation, protection against electric shock, guarding of moving parts, durability, and ergonomics.

Key Requirements

EN 60745-2-4:2003 lays out several key requirements that angle grinders must meet to comply with safety standards. One of the essential requirements is electrical safety, ensuring that the tool is adequately insulated and protected against electric shock. Another important aspect is mechanical safety, such as guarding of grinding discs to prevent accidental contact. The standard also addresses thermal safety, noise levels, and vibration, aiming to minimize health risks to operators.

Compliance and Certification

To ensure compliance with EN 60745-2-4:2003, manufacturers must perform thorough testing and evaluation of their angle grinders. This includes assessing electrical and mechanical safety features, as well as other requirements specified in the standard. Once the angle grinder meets all the necessary criteria, it can be certified to indicate its compliance with EN 60745-2-4:2003. This certification assures users that the tool has undergone rigorous testing and meets established safety standards.
