Welding consumables - Wire electrodes, strip electrodes, wires and rods for arc welding of stainless and heat resisting steels - Classification

This document specifies requirements for classification of wire electrodes, strip electrodes, wires and rods for gas-shielded metal arc welding, gas tungsten arc welding, plasma arc welding, submerged arc welding, electroslag welding and laser beam welding of stainless and heat-resisting steels. The classification of the wire electrodes, strip electrodes, wires and rods is based upon their chemical composition.This document is a combined specification providing for classification utilizing a system based upon nominal composition (system A), or utilizing a system based upon alloy type (system B).a)       Paragraphs which carry the label “classification according to nominal composition” and the suffix “system A”, or “ISO 14343-A”, are applicable only to products classified according to system A;b)       Paragraphs which carry the label “classification according to alloy type” and the suffix “system B”, or “ISO 14343-B”, are applicable only to products classified according to system B.c)        Paragraphs which carry neither label nor suffix letter are applicable to products that can be classified according to either system A or B or both.

This document specifies requirements for classification of wire electrodes, strip electrodes, wires and rods for gas-shielded metal arc welding, gas tungsten arc welding, plasma arc welding, submerged arc welding, electroslag welding and laser beam welding of stainless and heat-resisting steels. The classification of the wire electrodes, strip electrodes, wires and rods is based upon their chemical composition.

This document is a combined specification providing for classification utilizing a system based upon nominal composition (system A), or utilizing a system based upon alloy type (system B).

a)       Paragraphs which carry the label “classification according to nominal composition” and the suffix “system A”, or “ISO 14343-A”, are applicable only to products classified according to system A;

b)       Paragraphs which carry the label “classification according to alloy type” and the suffix “system B”, or “ISO 14343-B”, are applicable only to products classified according to system B.

c)        Paragraphs which carry neither label nor suffix letter are applicable to products that can be classified according to either system A or B or both.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
