Water-tube boilers and auxiliary installations - Acceptance tests Ingestion-build-279162 and upstream of blowpipes forThis European Standard covers direct fired steam boilers and hot water generators, including the auxiliaries. For the purposes of this standard, steam boilers and hot water generators are vessels and pipework systems in which: steam at a pressure higher than atmospheric pressure is generated for use external to the system; water is heated to a temperature higher than the saturation temperature at atmospheric pressure for use external to the system.
