Overview

SIST EN 12581:2006+A1:2010 is the European safety standard for machinery used in dip coating and electrodeposition (electrophoretic) coating of organic liquid coating materials. It applies to the design and construction of coating plants that include core equipment such as transport/hoist systems, dip and safety tanks, forced ventilation and ancillary items (pumps, filters, heaters). The standard addresses significant hazards when machinery is used as intended and sets requirements for marking, user information and minimum safe use.

Key topics and technical requirements

• Scope and exclusions
  • Applies to industrial dip/electrophoretic coating machinery (tank volume ≥ 1 m3).
  • Excludes automatic loading/unloading systems, lifting accessories, simple tanks without technical devices, preparation/supply/drainage machinery, water/waste treatment, web/coil coating machines and machines manufactured before publication.
• Hazard identification
  • Mechanical risks: shearing, crushing, entanglement, stability and entrapment.
  • Electrical risks: shock, external influences on electrical equipment.
  • Thermal risks: hot surfaces, heating-system hazards.
  • Noise, dangerous substances (solvents, vapours), fire and explosion.
  • Energy supply and control-system failures.
• Safety measures and verification
  • Guarding of danger points, protection against loss of stability and entrapment, slip/trip/fall prevention.
  • Electrical protection and measures against external influences.
  • Ventilation and exhaust requirements to control solvent concentrations, heating controls and over-temperature protection.
  • Explosion‑hazard zoning, ignition-source control and fire‑protection measures.
  • Requirements for emergency stop, control-system safety levels and verification/testing procedures.
• Information for use
  • Instruction handbook, equipment marking and user guidance are mandated.
• Annexes
  • Contains normative guidance for hazardous zones, LEL-based ventilation calculations, classification diagrams and references to exposure limit values.

Practical applications and typical users

• Manufacturers and machine designers - to design compliant dip and electrophoretic coating machinery.
• Plant engineers and integrators - to specify safe layouts, ventilation and control systems.
• Safety and compliance officers - to assess conformity with EU requirements and prepare documentation (marking, instructions).
• Inspection and testing bodies - to verify safety measures, explosion protection and control‑system integrity.
• Consultants and risk assessors - to evaluate hazards related to solvents, fire/explosion and operator safety.

Related standards and regulatory links

• References to EN ISO 12100 (machine safety principles / type C standard relationship).
• Informative annexes link the standard to EU Directives such as 2006/42/EC (Machinery Directive) and 94/9/EC (ATEX / explosive atmospheres).
• Useful when implementing plant safety, ventilation design and explosion-protection strategies for coating plants.
