Overview
EN 144-1:2018 specifies the dimensional, mechanical and marking requirements for inlet connections used to join gas cylinder valves to cylinders for respiratory protective devices (RPDs). Prepared by CEN/TC 79, this Part 1 standard focuses on inlet connections to ensure safety, interchangeability and reliable performance under impact and pressure testing.
Key Topics
- Scope and purpose: Sets dimensions and tolerances, impact-resistance criteria and mandatory marking for inlet connections of cylinder valves used with RPDs.
- Approved thread types: Only parallel threads M18x1,5 or M25x2, or taper 17E are permitted for RPD inlet connections. M18x1,5 and M25x2 are the preferred options.
- Dimensional conformity: Parallel and taper threads shall meet the referenced specifications (EN ISO 15245-1 for parallel threads; EN ISO 11363-1 for 17E taper thread).
- Impact resistance: The connection material must withstand an impact energy of (120 ± 3) J. Two assembled valves (excluding actuating means) are tested; distortion of sealing elements is permissible, but cracking of the valve body is not.
- Post-impact tests: After impact, valves must pass a hydraulic pressure test (1.2 × working pressure) and an internal tightness test. Total permissible leakage is not to exceed 180 cm3/h, and the valve must remain operable for emergency venting by hand or simple tool.
- Marking: Valves conforming to EN 144-1 must be marked with the standard number (EN 144-1), manufacturer identification, date of manufacture (at least year) and thread identification (e.g., 18P, 25P or 17E).
Applications
EN 144-1:2018 directly applies to manufacturers, test laboratories, procurement teams and safety engineers involved with respiratory protective devices that use gas cylinders (e.g., supplied-air systems, escape sets). Practical benefits include:
- Safety: Defined impact and pressure tests reduce the risk of catastrophic failure under mechanical shock.
- Interchangeability: Standardized thread types and markings simplify compatibility checks between valves and cylinders across manufacturers.
- Regulatory compliance: Clear identification and testing procedures support conformity assessments and national adoption.
Related Standards
This Part 1 is one element of a three-part series on gas cylinder valve connections for RPDs:
- EN 144-2 - Outlet connections (see EN 144 series)
- EN 144-3 - Outlet connections for diving gases (Nitrox and oxygen)
Normative references cited in EN 144-1:2018 include:
- EN ISO 11363-1 (17E taper thread)
- EN ISO 15245-1 (parallel threads M18x1,5 and M25x2)
- EN ISO 13341 (fitting of valves to cylinders)
- EN ISO 10286 and ISO/TR 11364 (terminology and thread guidance)
For manufacturers and specifiers, EN 144-1:2018 provides a practical, test-driven framework for ensuring inlet connections on cylinder valves meet safety, compatibility and marking expectations for respiratory protective equipment.
