IS0 9013:1992(E) Foreword IS0 (the international Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 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. International organizations, govern- mental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an lnter- national Standard requires \approvaI by at least 75 % of the member bodies casting a vote. International Standard IS0 9013 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Sub-Committee SC 8, Gas welding equipment.

INTERNATIONAL STANDARD IS0 9013:1992(E) Welding and allied processes - Quality classification and dimensional tolerances of thermally cut (oxygen/fuel gas flame) surfaces 1 Scope This International Standard is valid for materials suitable for oxygen cutting and for workpiece thick- nesses from 3 mm to 300 mm. It applies to cut metal surfaces produced by oxygen/fuel gas flame cutting and requires quality classification and dimensional tolerances. \ 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publi- cation, the editions indicated were valid. All stan- dards are subject to revision,’ and parties to agreements based on this International Standard are encouraged to investigate the possibility of ap- plying the most recent editions of the standards in- dicated below. Members of IEC and IS0 maintain registers of currently valid International Standards. IS0 1302:1978, Technical drawings - Method of in- dicating surface texture on drawings.

The process shall deliver sufficient thermal energy such that areas of the material in the cutting direction are heated up to this ignition temperature. The ignition temperature shall be below the melting temperature of the material. Cutting slag shall be liquid enough to be driven out of the cutting kerf by

Perpendicularity or angularity tolerance, U, is the distance between two parallel straight lines (con- tacting lines) that limit the cut face profile at the theoretically correct angle (i.e. at 90” for square edge cuts). The contacting lines are situa ted in a plane normal to both the workpiece su rface and to the cut face. KEY The perpendicularity tolerance and the angularity tolerance include deviations from straightness and flatness. 1 n is the roughness sampling length %, to Z5 are individual profile departures Ten point height of irregularities, I$, is the mean of the absolute values of the heights of the five highest profile peaks and the depths of the five deepest profile valleys within the sampling length (from IS0 4287-l).
