Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO 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, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
The main task of technical committees is to prepare International Standards. Draft International Standards adopted
by the technical committees are circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 9013 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 8,
Equipment for gas welding, cutting and allied processes.
This second edition cancels and replaces the first edition (ISO 9013:1992), which has been technically revised.
Annexes A and B of this International Standard are for information only.

6 Determination of the quality of cut surfaces
6.1 General
These requirements serve the purpose of indicating measuring procedures and measuring instruments by means
of which it is possible to determine and evaluate the characteristic values of cut surfaces.
When choosing the measuring instruments, care has to be taken that the error limits are not above 20 % of the
values of the characteristic values to be measured. Tables 1 and 2 indicate the precision and coarse measuring
instruments for the characteristic values.

6.2 Measuring
6.2.1 Measuring conditions
Measurements shall be carried out on brushed, free-from-oxides cuts outside areas including imperfections.
As reference element, the upper and lower sides of the thermally-cut work piece are taken. They shall be even and
clean.
For defining the straightness, the reference element and the straight measuring line shall be aligned to one another
so that the maximum distance between the straight measuring lines and the real surface equals a minimum. The
minimum condition is explained in detail in 3.7 of ISO 1101:1983.
6.2.2 Measuring point
6.2.2.1 General
The number and location of the measuring points depend on the shape and size of the work piece and sometimes
also on the intended use. The following indications may serve as a guideline.
© ISO 2002 – All rights reserved 9
---------------------- Page: 18 ----------------------
ISO 9013:2002(E)
The cut surfaces are classified in the tolerance fields according to the maximum measured values. Therefore, the
measuring points shall be located where the maximum measured values are to be expected. When choosing the
measuring points due consideration shall be given to the fact that the maximum values of the mean height of the
profile and of the perpendicularity or angularity tolerance may be found at different points of the cut. If measured
values are located at the lower limit of a tolerance field, additional measurements should be carried out due to the
uncertainty of the visual selection of the point with the expected maximum measured value. If measured values are
located at the upper limit of the tolerance field or if there are any doubts regarding some measuring results,
supplementary measurements shall be carried out on the same number of additional measuring points.
6.2.2.2 Number of the measuring points
The number and location of the measuring points shall be defined by the manufacturer.
If no requirement is specified, carry out:
u two times three measurements at a distance of 20 mm each on each meter of the cut;
Rz5 one time one measurement on each meter of the cut.
6.2.2.3 Location of the measuring points
The characteristic value of perpendicularity or angularity tolerance u only will be determined in a limited area of the
cut surface. The area shall be reduced by the dimension ∆a according to Table 3 from the upper and the lower cut
surface edges (see Figure 11).
The reason for the reduced cut face profile is to allow for the melting of the top edge.

Area for determination of the perpendicularity and angularity tolerances
Figure 11 — Definition of the measuring range for perpendicularity and angularity tolerances
For cut thicknesses below 2 mm, the measuring procedure to determine the perpendicularity or angularity tolerance
specifically has to be agreed upon.
The characteristic value of the mean height of the profile Rz5 only will be determined in a limited area of the cut
surface. The measurement is carried out at the point of the maximum surface roughness of the cut thickness, in
accordance with ISO 4288. For oxyfuel flame cutting as well as for plasma cutting, the measurement typically takes
place at a distance of 2/3 of the cut thickness from the upper cut edge; for laser cutting in the upper third from the
upper cut edge. For cut thicknesses below 2 mm, the measurement is carried out at a distance of 1/2 of the cut
thickness from the upper cut edge.
6.2.3 Procedure
The characteristic values for the cut surfaces will be determined, according to the type of measurement, by means
of the corresponding instruments listed in Tables 1 and 2.
The mean height of the profile Rz5 shall be measured at 15 mm from the cut length in the advance direction. The
measurement will take place in accordance with ISO 4288 using a tester as described in ISO 3274.
If a measuring wire or sensor for coarse measurement of the perpendicularity or angularity tolerance cannot be
introduced in the gap between shifting square and cut surface, a depth gauge with sensing point shall be used. In
the case of molten edges with unfinished projection, the latter will be considered in the perpendicularity or
angularity tolerance.
7 Quality of the cut surface
7.1 Characteristic values
The quality of the cut surfaces of thermally cut materials is described by the following characteristic values:
a) perpendicularity or angularity tolerance, u;
b) mean height of the profile, Rz5.
The following characteristic values may be used in addition:
c) drag, n;
d) melting of top edge, r;
e) possibly occurrence of dross or melting drops on the lower edge of the cut.
