Foreword
This document (CEN/TR 13259:2013) has been prepared by Technical Committee CEN/TC 121 “Welding and
allied processes”, the secretariat of which is held by DIN.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

Introduction
Requests for official interpretations of any aspect of this Technical Report should be directed to the Secretariat
of CEN/TC 121/SC 7 via the National Standards Body.
1 Scope
This Technical Report 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 and EN ISO 9012.
This Technical Report 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.
