SIST EN 474-10:2007/kprA1:2008

Overview

SIST EN 474-10:2007/kprA1:2008 is a European standard developed by CEN that specifies safety requirements for trenchers, a category of earth-moving machinery used in construction and excavation. This standard is part of the EN 474 series dedicated to earth-moving machinery safety and is aimed at improving operational safety, reducing risks, and ensuring compliance with applicable EU regulations such as Directive 2006/42/EC on machinery.

Prepared by the Technical Committee CEN/TC 151, this standard addresses essential safety and performance aspects of trenchers. The 2008 amendment (prA1) updates normative references related to noise emissions and reinforces compliance with EU directives. SIST EN 474-10:2007/kprA1:2008 is adopted or referenced by national standards bodies across Europe, facilitating harmonized safety practices.

Key Topics

• Safety Requirements for Trenchers: Specifies key design and operational criteria to minimize hazards during trencher use.
• Noise Emission Measurement: Incorporates updated ISO standards ISO 6393:2008 and ISO 6394:2008 for determining sound power levels and sound pressure noise at the operator’s station under stationary test conditions.
• Conformity with EU Machinery Directive: Ensures that trenchers designed according to this standard meet the essential safety requirements under Directive 2006/42/EC, supporting regulatory compliance across EU and EFTA member states.
• Technical Amendments: Details the modifications introduced in the 2008 draft amendment, including the addition of informative Annex ZB, which outlines the linkage with the EU Machinery Directive.
• Multilingual Official Versions: Published in English, French, and German, with other translations recognized under the responsibility of national CEN members.

Applications

This standard is crucial for:

• Manufacturers of Trenchers: To design and produce machinery that meets rigorous safety requirements, reducing operator risk and liability.
• Safety Inspectors and Regulators: Providing a benchmark for assessing trencher safety compliance and enforcing machinery safety legislation.
• Construction and Earthmoving Companies: Ensuring that the trenching equipment used on sites complies with the latest safety standards to protect operators and bystanders.
• Test Laboratories: Conducting sound emission tests as per the updated ISO standards referenced in the document.
• Standardization Bodies: For integration into national standards to harmonize safety practices across Europe.
