专家解读视频
This International Standard specifies requirements and test methods for pressure regulators in manifold systems for welding, cutting and allied processes.This International Standard is applicable to pressure regulators normally used for compressed gases up to 300 bar (30 MPa), for dissolved acetylene, methylacetylene-propadiene-mixtures (MPS) and carbondioxide (CO2), toregulate 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.
