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 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

SC 10, Unification of requirements in the field of metal welding.

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

revised.

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

machines for high quality welding and cutting:
⎯ Part 1: General principles, acceptance conditions
⎯ Part 2: Measurement of static and dynamic accuracy
⎯ Part 3: Calibration of instruments for measurement of gas flow and pressure
⎯ Part 4: Machines with 2-D moving optics

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
