The work of preparing International Standards is normally carried out through ISO techni
5、cal committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely w
6、ith the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft Int
7、ernational Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document m

See text overleaf. 2 ISO 2012 All rights reserved ISO 5172:2006/Amd.1:2012(E) Annex J (normative) Uniform designation system for oxyfuel nozzles In the oxyfuel welding and cutting industry, every equipment manufactu
17、rer has its own system for designating the size of oxyfuel nozzles for cutting, welding, as well as heating or brazing. These systems are based on a variety of different nozzle features and in many cases are completely arbitrary. In any case, it is currently impossible to identify a nozzle by model
18、number for a given manufacturer and cross-reference it to a different manufacturer to obtain like performance and size, i.e. there is no consensus among manufacturers on the designation of nozzles which have similar performance and uses. The following system of marking provides a common information
19、base that the operator can rely on to identify nozzle performance from one manufacturer to another. The overall intent of this system is to provide a common identification system that results in the safe operation of oxyfuel nozzles, i.e. operators are informed that they are using the correct nozzle
