This document refers to manual blowpipes and stationary machine blowpipes with free burning flames for heat treatment of work pieces. These blowpipes are, due to their type of construction, designed for special applications and do not fall under the scope of EN ISO 5172:2006 and EN ISO 9012:2011. This document does not apply to manual and machine cutting blowpipes according to EN ISO 5172:20061. This document contains technical regulations, specifications and tests. Blowpipes are intended for gaseous fuels in connection with oxygen, compressed air or aspirated air. Flow rates are not expressly limited and depend on the thermal process to be performed.
