1 Scope
This Standard describes hazards generated by laser processing machines, and specifies the safety requirements relating to radiation hazards and hazards generated by materials and substances. It also specifies the information to be supplied by manufacturers of such equipment.
It is applicable to machines using laser radiation to process materials.
It is not applicable to laser products, or equipment containing such products, which are manufactured solely and expressly for the following applications:
— photolithography;
— stereolithography;
— holography;
— medical applications (per IEC 601-2-22);
— data storage.

3 Definitions
For the purposes of this Standard, the definitions given in GB/T 15706.1-1995 and GB 7247-1995 and the following definitions apply.
3.1 Machine
Assembly of linked parts or components, at least one of which moves, with the appropriate actuators, control and power circuits, etc., joined together for a specific application, in particular for the processing, treatment, moving or packaging of material.
3.2 Laser processing machine
Machine in which (an) embedded laser(s) provide(s) sufficient energy/power to melt, evaporate, or cause a phase transition in at least a part of the workpiece, and which machine has the functional and safety completeness to be ready-to-use.
3.3 (Preventive) maintenance
Performance of those adjustments or procedures specified in user information, which are intended to be performed by the user for the purpose of assuring the intended performance of the product.
NOTE: Examples include replenishment of consumables and cleaning.
3.4 Manufacturer
Individual or organization that assembles the laser processing machine. Where a laser processing machine is imported, the importer assumes the duties of the manufacturer. An individual or organization that is responsible for modification of a machine is regarded as a manufacturer.
3.5 Modification
Change to the machine which makes it capable of processing materials in a manner which differs from the original design, or which makes it capable of processing materials different from what was envisaged in the original design, or which affects the safety characteristics of a machine.
