This document applies to acetylene manifold systems extending from the cylinder valve or the bundle outlet connections to the outlet connection of the main shut-off valve. It specifies requirements for design, materials and testing of cylinder manifold systems for the supply of acetylene for use in welding, cutting and allied processes.
This document applies to acetylene manifold systems in which one of the following acetylene sources is used or connected for collective gas withdrawal:
— Single individual cylinder;
— Multiple cylinders;
— Single individual bundle;
— Multiple bundles,
When a single individual cylinder with cylinder regulator according to ISO 2503 is directly connected to the cylinder valve, this document does not apply.
NOTE National regulations exist regarding limitation of the amount of single cylinders/bundles of acetylene on a single location (e.g. in warehouse or connected to a manifold system).
