EN ISO 23779:2025 PDF

Overview

EN ISO 23779:2025 (ISO 23779:2024) specifies safety and environmental requirements for shot blasting machinery used in foundry and metalworking environments. The standard covers wheel blasting, air blasting (dry and wet) and combined wheel/air systems, and addresses hazards, environmental impact and energy usage throughout the machine life cycle. It includes informative illustrations (Annex A), an interfaces overview (Annex C) and a normative noise test code (Annex B). EN ISO 23779:2025 also aligns with the EU Machinery Directive (see Annex ZA).

Key topics and technical requirements

• Scope and applicability
  • Applies to significant hazards, hazardous situations and events during intended use and reasonably foreseeable misuse.
  • Excludes high-pressure water jet and dry-ice blasting machinery; does not retroactively apply to machines manufactured before publication (can guide risk assessment).
• Risk reduction and safety measures
  • Guards and doors, interlocks and fixed guarding for operator protection.
  • Control systems and safety-related control functions including start/stop selection and failure modes.
  • Emergency stop requirements and safe integration with external equipment.
  • Electrical equipment and connectors for power, fresh/exhaust air, pressurized air, water and wastewater.
• Process-specific requirements
  • Wheel blaster and air blaster design safety measures.
  • Blasting chamber safety, access, and maintenance considerations.
  • Shot media transport and recovery systems to prevent ejection and spillage.
• Hazard classes and special topics
  • Wear-related hazards, static electricity control, noise reduction and measurement (Annex B), and management of hazardous substances and emissions.
• Environmental and energy aspects
  • Measures for energy efficiency, reduction of environmental impact across acquisition, production, use and end-of-life.
• Documentation and verification
  • Verification procedures, marking, and comprehensive instruction handbook requirements for installation, operation and maintenance.

Applications and who uses this standard

• Manufacturers and designers of shot blasting machinery to ensure compliant machine design and safety features.
• Plant managers, safety engineers and maintenance teams for safe installation, operation, servicing and risk assessments.
• Compliance officers and notified bodies for conformity assessment with the Machinery Directive.
• Integrators connecting blasting machines to conveyors, ducting, power supplies and respiratory air systems.
• Useful for improving noise control, energy efficiency, waste minimization and environmental compliance in blasting operations.
