BS EN ISO 1071:2015 pdf free.Welding consumables – Covered electrodes, wires, rods and tubular cored electrodes for fusion welding of cast iron – Classification.
BS EN ISO 1071 specifies requirements for classification of covered electrodes for manual metal arc welding, wire electrodes for metal arc welding, tubular cored electrodes for metal arc welding with and without a gas shield, rods for TIG-welding, and rods for oxy-fuel gas welding of unalloyed cast irons. Classification is based on the chemical composition of wires and rods and on the all-weld metal deposit for tubular cored and covered electrodes.

3 Classification
3.1 Wire electrodes and rods
For wire electrodes and rods classified in accordance with their chemical composition (see Table 2 and
Table 3), the classification is divided into three parts.
a) The first part gives a symbol indicating the product to be identified.
b) The second part indicates the type of alloy (C for cast iron).
c) The third part gives a symbol indicating the chemical composition of the wire electrode or of the rod.
3.2 Tubular cored electrodes
For tubular cored electrodes classified in accordance with the all-weld metal chemical composition
produced with an appropriate shielding gas, the classification is divided into four parts.
a) The first part gives a symbol indicating the product to be identified.
b) The second part indicates the type of alloy (C for cast iron).BS EN ISO 1071 pdf download.
