Overview

EN 144-2:2018 is a European standard developed by CEN that specifies the dimensions, tolerances, and marking requirements for outlet connections used in gas cylinder valves for respiratory protective devices. It applies broadly to valves for breathable air, oxygen, and oxygen/nitrogen mixtures, explicitly excluding diving applications. This standard ensures compatibility and safety when connecting regulators to cylinder valves across various respiratory protection scenarios.

This document supersedes the earlier EN 144-2:1998 and integrates updates reflecting advances in technology and regulatory needs, including new pressure classifications and compliance with EN ISO 12209 for breathable air connections. It forms part of a multi-part series addressing gas cylinder connections in respiratory protection, supporting harmonized equipment interfaces in Europe.

Key Topics

• Scope and Applicability:
  Defines outlet connection requirements for respiratory protective devices except diving uses. Ensures interchangeability and safety across manufacturers and users.

• Connection Classifications:
  Outlet connections are categorized by gas type and working pressure:

  • Types A1, A2, A3 for breathable air (up to 400 bar)
  • Types O1, O2 for oxygen (up to 300 bar)
  • Types M1, M2 for oxygen/nitrogen mixtures (up to 300 bar)

• Dimensional and Tolerance Specifications:
  Precisely defines size, form, and tolerance to guarantee proper fitting and pressure resistance. Includes detailed diagrams and measurements conforming to ISO 2768-mk.

• Marking Requirements:
  Mandates clear identification on valves including:

  • Standard reference (EN 144-2)
  • Manufacturer identification
  • Manufacture year
  • Thread type and maximum working pressure (e.g., A1/200 bar)
    Markings ensure traceability and safe use.

• Integration with Related Standards:
  Aligns outlet connection designs for breathable air with EN ISO 12209 and references EN 144-1 for inlet connection standards. This synergy promotes comprehensive standardization of respiratory protective device connections.

Applications

EN 144-2:2018 is critical for manufacturers, safety engineers, and regulatory bodies involved in the design, production, testing, and certification of respiratory protective equipment (RPE) that uses compressed gas cylinders. Practical applications include:

• Manufacturing Respiratory Devices:
  Ensuring consistent valve design supports safety, compatibility, and interchangeability in devices such as self-contained breathing apparatus (SCBA), industrial respirators, and emergency escape systems.

• Regulator and Valve Assembly:
  Facilitates safe and reliable connections between gas cylinders and regulators, reducing risks of leaks or incompatibility especially under high operating pressures.

• Safety and Compliance Testing:
  Enables conformity assessment with European and international safety regulations, supporting market access and consumer protection.

• Maintenance and Inspection:
  Provides reference criteria to verify valve outlets during routine checks, ensuring that markings, dimensions, and pressure ratings remain compliant.

Related Standards

• EN 144-1: Respiratory protective devices - Gas cylinder valves - Part 1: Inlet connections
  Complements EN 144-2 by addressing the inlet interface of cylinder valves.

• EN ISO 12209: Gas cylinders - Outlet connections for gas cylinder valves for compressed breathable air
  Specifies outlet connection standards for breathable air, adopted within EN 144-2 for consistency.

• EN 144-3: Respiratory protective devices - Gas cylinder valves - Part 3: Outlet connections for diving gases Nitrox and oxygen
  Focuses on outlet connections for diving applications, excluded from EN 144-2’s scope.

• ISO 10286: Gas cylinders - Terminology
  Offers standardized definitions referenced to promote uniform understanding of terms within EN 144-2.

---

By adhering to EN 144-2:2018, manufacturers and users of respiratory protective devices can ensure enhanced safety, standardized connections, and regulatory compliance, fostering reliable performance in critical respiratory protection applications.
