Resumen:
This standard specifies requirements and test methods for pressure regulators in manifold systems for wel-ding, cutting and allied processes. This is applicable to pressure regulators normally used for compressed gases up to 300 bar, for dissolved acetylene, methylacetylene-propadiene-mixtures (MPS) and carbondioxide (CO2), to regulate the pressure at the outlet of high-pressure lines from manifold gas cylinders. It is not applicable to pressure regulators fitted directly to the gas cylinders, as defined in ISO 2503 or to pressure regulators for liquefied petroleum gases.
