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 2.

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 document may be the subject of patent

rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 15616-4 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee

This first edition of ISO 15616-4 cancels and replaces ISO/TS 17477:2003, which has been technically

ISO 15616 consists of the following parts, under the general title Acceptance tests for CO -laser beam

Requests for official interpretations of any aspect of this part of ISO 15616 should be directed to the

Secretariat of ISO/TC 44/SC 10 via a national standards body, a complete listing which can be found at

This part of ISO 15616 provides minimum requirements for acceptance testing, using practical test methods,

for CO -laser beam machines for high quality welding and cutting in two dimensions (2-D), having a fixed

This part of ISO 15616 is not applicable to CO -laser beam machines which use an articulated robot, nor does

it apply to work stations, such as a welding positioner, fixed board cutter, etc.

This part of ISO 15616 does not cover hazard protection devices, such as those for discharging chips and

longest distance between any two points that is made by three or more straight intersects

trace the trajectory of the machining head when the laser machine is being operated and mark it on paper

using a ballpoint pen, an equivalent marking pen installed on the tip of the machining head, a low-power laser

Judgement criteria/allowance values are applied to machines classified into two types:

The laser machine under test shall be installed in such a way that the welding and cutting operations will not

The power source for the laser machine and its cooling system shall conform with the manufacturer's

specifications for the equipment. Output voltage fluctuations shall be within ± 10 % of the nominal voltage.

If the cooling system is not supplied by the welding and cutting equipment manufacturer, it shall nevertheless

conform with the welding and cutting equipment manufacturer's specifications for water flow rate, temperature

The quality of the cooling water (purity, conductivity, pH, etc.) shall be as specified by the welding and cutting

The flow rate and quality of the laser gases, assist gases or shield gas (for plasma removal, cutting and

welding), and purging gases shall be as specified by the welding and cutting equipment manufacturer.

Technical information necessary for operation, maintenance and control of equipment, and at least the

minimum information related to the safety of welding and cutting equipment, shall be provided by the

Verify that all specified parts of the equipment are available and properly installed.

Check the following machine variables for accuracy in accordance with 5.2.3 and 5.2.4:

The measuring instruments used for the accuracy tests shall be calibrated measuring instruments, such as

standard scale, tape measure, dial gauge and/or steel wire, or other measuring instruments agreed between

The laser machine shall be used to draw a diagram, shown in Figure 1, with external dimensions

800 mm × 800 mm. The starting position shall be A and follow the sequence as listed under Figure 1, i.e. A, B,

C, D, A, C, H, etc. For laser machines with an effective machining range less than 800 mm × 800 mm, the

largest square covering the effective machining range shall be drawn. The pattern shall be drawn at a speed

of 1 m/min using the numerical control system of the machine. Deviations from the intersections, meandering

of trajectories, and deviations of arc trajectories shall be monitored in accordance with the following

procedures. For laser machines with a single-sided drive, the test shall be carried out on the driving side.

The pattern shown in Figure 1 shall be drawn in the specified sequence using the following criteria.

d) The circle shall be overwritten once in both the clockwise and counterclockwise directions.
