been prepared under the
direction of the Engineering
Sector Committee, was Dublished Date Comments
National foreword
This British Standard is the official English language version of EN 12536:2000 It partidy supersedes BS 14531972
The UK participation in its prepaxation was entrusted to Technical Committee WEE/39, Welding consumables, which has the responsibility to:
- aid enquirers to understand the text,
- present to the responsible European committee any enquiries on the interpretation, or proposais for change, and keep the UK interests informed
- monitor related international and European developments and promulgate them in the UK
A list of organizations represented on this committee can be obtained on request to its secretary

This standard specifies a classification in order to designate rods for gas welding of non alloy and creep-resisting steels in terms of the chemical composition of the rod
This European Standard incorporates by dated or undated reference, provisions from other publications These normative references are cited at the appropriate places in the text and the publications are listed hereafter For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when
incorporated in it by amendment or revision For undated references the latest edition of the publication referred to applies
EN 759 Welding consumables - Technical delivery conditions for welding filler
metals - Type of product, dimensions, tolerances and marking
IS0 31-0:1992 Quantities and units - Part O: General principles
A rod shall be classified with the symbol for its chemical composition in Table 1 Information
about welding behaviour is given in annex A
The classification is divided into two parts:
1) The first part gives a symbol indicating the product/process to be identified;
2) The second part gives a symbol indicating the chemical composition of the rod
The symbol for the rod used in the gas welding process shall b
the letter O
The symbol in Table 1 indicates the chemical composition of the rod, determined under
conditions given in clause 5

Chemical analysis is performed on specimens of the rod Any analytical technique can be
used, but in case of dispute reference shall be made to established published methods
NOTE: See annex B
Technical delivery conditions shall meet the requirements in EN 759
A rod for gas welding has a chemical composition within the limits for the alloy symbol O III of Table 1
The designation will be:
Rod EN 12536 - O III
where,
EN 12536 = standard number;
O = rod/gas welding (see 4.1);
III = chemical composition of rod (see Table 1)
