SIST EN 474-8:2007/kprA1:2008

Overview

EN 474-8:2006/prA1 - Earth-moving machinery - Safety - Part 8: Requirements for graders is a CEN draft amendment prepared by Technical Committee CEN/TC 151. It updates the Part 8 safety requirements for graders and includes informative Annexes (ZA and newly added ZB) that explain the relationship between the standard and EU Directive 2006/42/EC (the Machinery Directive). The amendment reference (prA1, June 2008) signals changes to the original 2006 text and to normative references (for example, EN ISO 7096).

This standard is focused on ensuring graders meet recognized safety practices for design, manufacture, testing and instructions, and it supports a presumption of conformity with relevant essential requirements of the Machinery Directive when correctly applied.

Key Topics

The standard addresses core machine-safety topics relevant to graders, including:

• Operator protection - safety measures related to cabs, ROPS/FOPS considerations and protection from hazards.
• Controls and human-machine interface - requirements for control layout, ergonomics and safe operation.
• Stability and structural integrity - design considerations to reduce tipping, collapse or structural failure risks.
• Visibility and lighting - requirements to improve operator sightlines and machine conspicuity.
• Protective guards and shields - safeguarding of moving parts and potential pinch points.
• Maintenance, inspection and accessibility - safe service access and procedures to reduce maintenance risks.
• Information, marking and documentation - operator manuals, warning labels and compliance information.
• Normative references and testing - cross-references to standards such as EN ISO 7096:2000 and test methods used to verify compliance.

Note: This summary highlights topic areas covered by the amendment; consult the full standard text for precise technical clauses and test criteria.

Applications / Who Uses It

EN 474-8:2006/prA1 is practical for stakeholders involved in the lifecycle of graders:

• Manufacturers and designers - to design and certify graders that meet harmonized European safety expectations.
• Safety and compliance engineers - to demonstrate conformity with the Machinery Directive and prepare technical files.
• Test laboratories and inspectors - to apply referenced test methods and verify compliance.
• Procurement and fleet managers - to specify safety requirements when buying or leasing graders.
• Regulators and notified bodies - for assessing conformity and market surveillance.

Using this standard helps reduce operator risk, improve machine reliability and streamline regulatory compliance in Europe.
