ISO 15616-4:20 08规定了使用实用测试方法对用于二维(2-D)高质量焊接和切割的CO2激光束机进行验收测试的最低要求，该机器在压板上具有固定工件和移动光学器件。 ISO 15616-4:20 08不适用于使用铰接式机器人的CO2激光束机，也不适用于包括工作站的机器，如焊接定位器、固定板切割机等。 ISO 15616-4:20 08不涵盖危险保护装置，例如用于排放焊接和切割过程中产生的切屑和颗粒的装置。

ISO 15616-4:2008 provides minimum requirements for acceptance testing, using practical test methods, for CO₂-laser beam machines for high quality welding and cutting in two dimensions (2-D), having a fixed workpiece on the platen and moving optics. ISO 15616-4:2008 is not applicable to CO₂-laser beam machines which use an articulated robot, nor to those which include a work station, such as a welding positioner, fixed board cutter, etc. ISO 15616-4:2008 does not cover hazard protection devices, such as those for discharging chips and particles generated during welding and cutting.
