20、 standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical 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. Internationa
21、l organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended fo

27、ous types of unalloyed cast irons.Applications for welding consumables classified to this International Standard: production welding, that means welding of cast materials during the process of production. In that way, the quality of the casting shall be ensured in accordance with the guaranteed prop
28、erties and to the requirements of the application; repair welding of castings which are damaged during service; welding for construction purposes where cast irons are joined to themselves or to other ferrous or non-ferrous metals.The following methods are used for the welding of cast irons: using a
29、welding consumable which produces a weld metal similar to the parent metal. High preheating is required (typical temperature range 550 C to 650 C); using a welding consumable which produces a weld metal dissimilar to the parent metal. No or only low preheating is required.This International Standard
30、 contains different types of welding consumables because the chemical composition of welding rods and wire electrodes, as well as the all-weld metal of the corresponding covered electrodes and tubular cored electrodes, is similar.Additionally, to the welding consumables specified in this Internation
31、al Standard, consumables classified to other standards can be used (see Annex A).

33、ns. Classification is based on the chemical composition of wires and rods and on the all-weld metal deposit for tubular cored and covered electrodes.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its applicati
