SIST EN 474-7:2007/kprA1:2008

Overview

EN 474-7:2006/prA1 is a CEN draft amendment covering safety requirements for scrapers, a class of earth-moving machinery. Prepared by Technical Committee CEN/TC 151, this prA1 amendment (June 2008) updates the original EN 474-7:2006 and clarifies the standard’s relationship with the EU Machinery Directive 2006/42/EC. The document updates normative references for noise measurement and adds informative annexes (ZA and new Annex ZB) that support regulatory conformity assessment.

Key topics and requirements

• Scope: Safety requirements specifically applicable to scrapers within the EN 474 series for earth-moving machinery (safety).
• Normative references updated: Replaces earlier draft ISO references with the finalized standards:
  • ISO 6393:2008 - determination of sound power level (stationary test conditions)
  • ISO 6394:2008 - determination of emission sound pressure level at the operator’s position (stationary test conditions)
• Noise and operator protection: The amendment revises clauses referencing sound power and operator emission sound pressure level tests to the 2008 ISO versions, indicating an emphasis on standardized noise measurement for operator safety and regulatory compliance.
• Regulatory alignment: Addition of Annex ZB which explains the relationship between this European Standard and the Essential Requirements of EU Directive 2006/42/EC (Machinery Directive). Compliance with the standard’s normative clauses gives a presumption of conformity with relevant essential requirements within its scope.
• Document status and adoption: The prA1 is a draft amendment submitted for unique acceptance; CEN members are required to implement approved amendments as national standards without alteration.

Applications and users

This standard (and its prA1 amendment) is valuable for:

• Manufacturers and designers of scrapers seeking to meet European safety and noise-emission expectations.
• Compliance and certification bodies assessing conformity with EN standards and the Machinery Directive.
• Health & safety managers and equipment procurement teams in construction and earthmoving operations who require machines that meet recognized safety benchmarks.
• Standards committees and national bodies implementing and translating CEN standards within member states.

Practical uses include design verification, noise assessment at operator positions, technical documentation for CE marking, and tender/specification development for safe scraper equipment.
