ISO 10524-2:2018

Overview

ISO 10524-2:2018 - "Pressure regulators for use with medical gases - Part 2: Manifold and line pressure regulators" - specifies design, construction, type testing, and marking requirements for manifold pressure regulators and line pressure regulators used in medical gas pipeline systems. The standard covers regulators supplied as individual units or as components within assemblies for gases such as oxygen, medical air, and oxygen/nitrous oxide mixtures. It applies to manifold regulators with nominal inlet pressures up to 30 000 kPa (300 bar) and line regulators supplied downstream with pressures up to 3 000 kPa (30 bar). It does not apply to vacuum pipeline systems (see ISO 10079‑3).

Key technical topics and requirements

ISO 10524-2:2018 focuses on safety, performance and compatibility in healthcare gas systems. Major topics include:

• Design and construction
  • Materials, cleanliness, and usability requirements
  • Pressure-adjusting devices and filtration
  • Connectors (inlet and outlet) for manifold and line regulators
• Performance and safety testing
  • Type tests including functional and flow characteristics, endurance, and leakage
  • Mechanical strength tests for high- and low-pressure sides
  • Pressure-relief device performance and safe relief of excess pressure
  • Resistance to ignition for materials and lubricants used in regulators
• Measurement and instrumentation
  • Requirements for pressure gauges and integrated digital gauges
  • Test methods for outlet pressure variation and transient behaviour
• Marking, colour coding and documentation
  • Durable markings, colour coding aligned with medical gas nomenclature, packaging and manufacturer information to support installation and maintenance

Practical applications and who uses this standard

ISO 10524-2:2018 is used to ensure reliable, safe pressure regulation in medical gas distribution systems. Typical users and applications:

• Medical device manufacturers designing and certifying manifold and line pressure regulators
• Hospital biomedical engineering teams specifying equipment for medical gas pipeline systems
• Procurement and compliance officers assessing supplier conformity to international standards
• Test laboratories performing type testing, endurance, leakage and ignition-resistance tests
• Installation and maintenance contractors following manufacturer information and marking requirements for safe operation

Adoption of ISO 10524-2 helps reduce risk (leakage, overpressure, ignition), ensures compatibility across systems, and supports regulatory compliance in healthcare facilities.
