BS EN ISO 3580:2008 Welding consumables. Covered electrodes for manual metal arc welding of creep-resisting steels. Classification.
BS EN ISO 3580:2008 proposes a classification aimed at designating covered electrodes, primarily in terms of the chemical composition of the allweld metal.
BS EN ISO 3580:2008 specifies requirements for classification of covered electrodes, based on the allweld metal in the heat-treated condition, for manual metal arc welding of ferritic and martensitic creep-resisting and low alloy elevated temperature steels.
BS EN ISO 3580:2008 is a combined specification for classification utilizing a system based upon the chemical composition of the all-weld metal, with requirements for the yield strength and the average impact energy of 47 J of all-weld metal, or utilizing a system based upon the tensile strength and the chemical composition of all-weld metal.

BS EN ISO 3580:2008 contains:
- Normative references
- Classification
- Symbols and requirements
- Mechanical tests
- Chemical analysis
- Fillet weld test
- Retest
- Technical delivery conditions
- Examples of designation
It should be noted that the mechanical properties of all-weld metal test specimens used to classify the electrodes will vary from those obtained in production joints because of differences in welding procedure such as electrode diameter, width of weave, welding position and material composition.
BS EN ISO 3580:2008 supersedes BS EN 1599:1997 which is withdrawn.
