Overview

EN 14594:2018 - Respiratory protective devices - Continuous flow compressed air line breathing devices - Requirements, testing and marking - is a European Standard (CEN) that defines minimum requirements, test methods and marking for continuous-flow compressed air line breathing devices (RPDs). It covers devices used with full face masks, half masks, hoods, helmets or suits, and includes equipment used in abrasive blasting operations. Escape RPD and diving apparatus are explicitly excluded. The standard combines design, material and performance requirements with laboratory and practical performance tests to assess conformity.

Key Topics

• Scope & classification: Types of continuous flow compressed air line breathing devices and their intended use cases.
• Design and materials: Requirements for ergonomics, durable materials, body harnesses/belts and connections between RPD, breathing hoses and facepieces (mask, hood, helmet, suit).
• Compressed air supply components: Requirements for compressed air supply tubes, couplings, pressure reducers, relief valves and mobile supply systems.
• Performance characteristics: Tests and limits for air flow rates, breathing resistance, inward leakage, carbon dioxide content of inhaled air, resistance to kinking and collapse, heat and flammability resistance, and electrostatic properties.
• Testing procedures: Laboratory and practical performance tests including pre-conditioning (e.g., low temperature), work simulation, strength tests for hoses and couplings, and warning-device verification.
• Marking & documentation: Requirements for product marking and information to be provided for safe selection and use.

Practical Applications

• Ensures safety and reliable operation of continuous-flow compressed air line RPDs used in industrial applications such as abrasive blasting, painting, chemical handling and confined-space work.
• Supports product design and quality assurance for manufacturers developing compressed air line systems, masks, hoods and associated breathing hoses and couplings.
• Provides criteria and test methods for third‑party testing laboratories and certification bodies to verify conformity.
• Helps procurement officers, health & safety managers and PPE coordinators specify compliant RPDs and ensure workplace respiratory protection meets recognized European requirements.

Who should use EN 14594:2018

• RPD manufacturers and product designers
• Test laboratories and conformity assessment bodies
• Occupational safety professionals and PPE procurement teams
• Certification/approval authorities and quality assurance specialists

Related guidance

• EN 14594:2018 should be used alongside other standards and guidance addressing facepieces, respirator classes and workplace respiratory protection to ensure a complete compliance and safety program for respiratory protective devices.

Keywords: EN 14594:2018, respiratory protective devices, continuous flow compressed air line breathing devices, RPD, testing and marking, compressed air supply tube, breathing hose, inward leakage, abrasive blasting.
