EN 62841-3-6:2014/A11:2017

Overview

EN 62841-3-6:2014/A11:2017 is a European standard published by CLC, focused on electrical safety requirements for motor-operated transportable diamond drills equipped with a liquid system. This amendment to the core standard addresses the unique safety aspects related to these specific tools and provides updated guidance for manufacturers, importers, and users. It modifies the requirements for marking, user instructions, and the declaration of noise and vibration values, thereby supporting compliance with essential EU directives.

Key Topics

• Scope of Application: The standard applies specifically to transportable diamond drilling machines with integrated or connected liquid systems, commonly used in construction and professional drilling operations.
• Safety Marking and Instructions: Manufacturers are required to provide clear information regarding noise emission values, measured according to standardized methods, along with appropriate warnings and instructions for safe operation.
• Noise Emission Declaration: The amendment clarifies that noise values must be clearly documented for comparison purposes and for preliminary assessment of operator exposure.
• Removal of Vibration Declaration: The amendment deletes the requirement to declare vibration emission values for transportable tools-this is no longer necessary for compliance.
• Operator Protection: Clear warnings must be included in the documentation about potential differences in noise emission during real-world use and the importance of evaluating operator exposure based on actual usage conditions, including idle and off periods.

Applications

EN 62841-3-6:2014/A11:2017 is highly relevant for:

• Manufacturers: Assists in designing and producing compliant diamond drilling machines for the European market, ensuring safety and adherence to legal obligations.
• Importers and Distributors: Helps verify tools meet EU safety requirements before placing them on the market.
• Construction and Industrial Users: Provides guidance on interpreting marking and instructions, enabling safer use of transportable diamond drills with liquid systems.
• Regulatory Agencies and Safety Inspectors: Offers a reliable benchmark for safety audits, market surveillance, and accident prevention related to electrically powered transportable tools.

The standard ultimately helps reduce workplace hazards by enhancing user awareness and product safety.

Related Standards

• EN 62841 Series: Covers the safety of electric motor-operated hand-held tools, transportable tools, and lawn and garden machinery.
• EN 62841-1: General requirements for the safety of all electric motor-operated tools.
• EN 62841-3-1 to EN 62841-3-12: Additional parts specify particular requirements for various types of transportable tools.
• ISO 3744: Reference for methods of measuring noise emission values.
• EU Machinery Directive 2006/42/EC: Provides broader safety requirements for machinery marketed in the European Union.

Practical Value

Implementing EN 62841-3-6:2014/A11:2017 ensures products meet essential safety criteria, reduce occupational risks, and facilitate smoother market entry across Europe. By following this standard, organizations can achieve higher levels of tool safety, user confidence, and regulatory compliance, particularly in the construction and heavy equipment sectors.
