ISO 10524-2:2018 specifies design, construction, type testing, and marking requirements for manifold pressure regulators (as defined in 3.7) and line pressure regulators (as defined in 3.5) intended for use in medical gas pipeline systems.

Examples of gases include oxygen, medical air and oxygen/nitrous oxide mixtures.

ISO 10524-2:2018 applies to manifold pressure regulators and line pressure regulators supplied as individual units or to the relevant components incorporated within an assembly.

Manifold pressure regulators are intended to be connected to a manifold system which has a nominal inlet pressure, P1 of up to 30 000 kPa (300 bar).

Line pressure regulators are intended to be connected downstream of the manifold pressure regulator with a supply pressure up to 3 000 kPa (30 bar).

ISO 10524-2:2018 does not apply to pressure regulators for use with vacuum pipeline systems.

NOTE Requirements for pressure regulators for use with vacuum pipeline systems are covered in ISO 10079‑3.
