As ISO 2503, Gas welding equipment - Pressure regulators and pressure regulators with flow-metering devices for gas cylinders used in welding, cutting and allied processes up to 300 bar (30 MPa), does not cover the pressure regulators used on gas pipelines and distribution systems, with a lower inlet pressure than the cylinder regulators, this standard has been proposed.
The industry needs such a standard to refer to for them. These regulators are by now only covered in other standard systems like AS or CGA.

This International Standard specifies requirements for pressure regulators to be connected to industrial gas distribution pipelines of
- compressed gases and Carbon Dioxide up to 60 bar (6 MPa),
- dissolved acetylene,
- liquefied petroleum gases (LPG),
- methylacetylene-propadiene mixtures (MPS)
for use in welding, cutting and allied processes.
This International Standard does not cover pressure regulators intended for direct use on cylinder and bundles. Such regulators comply respectively with the safety requirements of ISO 2503 or ISO 7291.
