BS/EN 560-2018 pdf download.Gas welding equipment – Hose connections for equipment for welding, cutting and allied processes.
This BS/EN 560 lays down the dimensions and specifies the characteristics of the constituent parts of hose connections for welding, cutting and allied processes, for example for pressure regulators according to EN Iso 2503 and blowpipes. The suitability of the hose connections mentioned below will be considered according to the applied pressure range. This document does not cover the design of the hose tail inserted into the hose. This is specified in EN 1256.
