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.
