Scope

This document specifies the design, structure, type testing, and marking requirements for manifold pressure regulators (see 3.6) and pipeline pressure regulators (see 3.4) intended for use in medical gas pipeline systems.
Example: Gases include oxygen, medical air, and oxygen/nitrous oxide (laughing gas) mixtures.
This document applies to manifold pressure regulators and pipeline pressure regulators, either used individually or assembled with related components.
Manifold pressure regulators are intended to be connected to manifold systems, with a nominal inlet pressure of p1 up to 30,000 kPa (300 bar).
Pipeline pressure regulators are intended to be connected downstream of manifold pressure regulators, with a nominal inlet pressure of p1 up to 3,000 kPa (30 bar).
This document does not apply to pressure regulators used in vacuum pipeline systems.
Note: Pressure regulators used in vacuum pipeline systems are specified in YY/T 0636.3.
