Overview

EN 12649:2008+A1:2011 is a CEN safety standard for concrete compactors and smoothing machines. It defines the scope, hazard analysis and technical safety measures for internal and external vibrators, vibrating beams and smoothing machines when used as intended (including reasonably foreseeable misuse). The standard also applies to hand‑held motor‑operated concrete vibrators referenced in EN 60745-2-12, with added requirements for electronically controlled systems. EN 12649 supports compliance with the EU Machinery Directive (2006/42/EC) and includes illustrations and dimensional guidance in annexes.

Key topics and technical requirements

The standard focuses on eliminating or reducing significant hazards through design, verification and documentation. Key topics include:

• Risk assessment and scope: Coverage of significant hazards, hazardous situations and events relevant to concrete compactors and smoothing machines; Type C standard precedence over more general (A/B) standards.
• Machine categories: Definitions for internal vibrators, external vibrators, vibrating beams, smoothing machines and portable units; exclusions (e.g., auxiliary power sources, remote‑controlled or robotic smoothing machines).
• Safety measures:
  • Mechanical safeguards - prevention of drawing‑in and guarding of rotating or transmission parts.
  • Electrical safety and EMC - protection against direct/indirect contact, durability against dust/wetness and requirements for electronically controlled systems.
  • Noise and vibration - measures addressing hearing risk and hand‑arm vibration exposure.
  • Hydraulic/pneumatic risks - high‑pressure fluid injection hazards.
  • Fire protection and thermal hazards - hot parts and combustion engine risks.
  • Stability and mounting - fixation, lifting and towing points for external vibrators and beams.
• Verification and testing: Procedures to verify that safety requirements and protective measures are effective.
• Information for use: Required marking, warning signs, and comprehensive operation and maintenance manuals for safe use.
• Annexes: Illustrations (Annex A) and dimensions of smoothing machines (Annex B); Annex ZA links to the Machinery Directive.

Applications and who uses this standard

EN 12649 is used by:

• Manufacturers and designers of concrete compactors, smoothing machines and vibrators to design compliant, safe equipment.
• Safety engineers and risk assessors to evaluate machine hazards and specify protective measures.
• Test laboratories and conformity assessors for verification and CE marking.
• Purchasers, rental companies and site managers to ensure supplied machines meet safety requirements.
• Regulators and inspectors for compliance checks on construction equipment safety.

Practical applications include machine design, guarding specification, EMC and electrical design, noise/vibration control, user documentation and conformity assessment for CE marking.
