General Information
Overview
EN ISO 15616-4:2021 (identical to ISO 15616-4:2008) defines minimum requirements and practical test methods for acceptance tests of CO2‑laser beam machines used for high‑quality welding and cutting with 2‑D moving optics (fixed workpiece on a platen, moving optics). The standard was adopted by CEN in 2021 and is part of the ISO 15616 series addressing acceptance testing for CO2 laser welding/cutting equipment.
The standard explicitly excludes machines that use an articulated robot, workstations such as welding positioners or fixed board cutters, and hazard protection devices (e.g., chip/particle discharge systems).
Key topics and technical requirements
EN ISO 15616-4:2021 focuses on machine performance verification and acceptance criteria, including:
Classification
- Class A: laser source built into the moving machine
- Class B: laser source not built into the moving machine
Acceptance test conditions
- Installation, power supply stability (±10% allowed fluctuation), cooling system and gas supply per manufacturer specifications, and provision of technical/user information.
Machine accuracy verification (practical test methods)
- Trajectory accuracy: 800 mm × 800 mm pattern (or maximum effective range); measures deviation at intersections, meandering and arc deviations.
- Straightness of motion (X and Y): pen/low‑power beam marking, steel wire reference, measured at 1 m intervals.
- Squareness between X and Y axes: diagonal length difference on a 2 m square (or effective range).
- Positioning accuracy (X and Y): unidirectional 1 m moves, compare programmed vs measured distance.
- Machining speed accuracy: compare programmed vs actual at 1/4, 1/2 and full speeds.
Acceptance limits (examples)
- Deviation of intersections: Class A ≤ 0.5 mm, Class B ≤ 0.2 mm
- Meandering of trajectory: Class A ≤ 0.2 mm, Class B ≤ 0.1 mm
- Straightness (X/Y): Class A ≤ 0.4 mm, Class B ≤ 0.1 mm
- Positioning accuracy: Class A ±0.2 mm, Class B ±0.1 mm
- Machining speed error: Class A ±5%, Class B ±2%
Test report
- Templates/sample reports provided in annexes for Class A and Class B machines.
Applications and users
This standard is practical for:
- OEMs and manufacturers of CO2‑laser beam machines for specifying and proving machine performance.
- Commissioning and quality engineers performing acceptance testing at delivery.
- Integrators, test laboratories and purchasers who need objective, repeatable acceptance criteria.
- Procurement/specification writers creating supplier contracts and factory acceptance test (FAT) criteria.
Use EN ISO 15616-4:2021 when you need standardized, repeatable tests for 2‑D moving‑optics CO2 laser systems to verify trajectory, positioning and speed accuracy for high‑quality welding and cutting.

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
