This standard specifies the minimum requirements for documentation, marking and labelling for all laser products classified in accordance with IEC 60825-1, including laser diodes and all laser devices integrated in laser units or laser processing machines. This standard is not applicable for complete laser units or laser processing machines that incorporate a laser device. It is not applicable to incoherent lamps and other similar sources such as LEDs that are required to comply with IEC 62471. This standard specifies requirements for technical data sheets and information for the user. The provision of technical data and safety information is an integral part of a product and is essential for its safe use. The documentation shall cover the whole life cycle, transport, assembly, system integration, normal operation, maintenance, service, decommissioning and disposal. This standard has been prepared by ISO/TC 172/SC 9 "Electro-optical systems" in collaboration with CEN/TC 123 "Lasers and photonics", the secretariat of which is held by DIN (Germany), with significant participation by German experts. For this purpose, Working Committee NA 027-01-18 AA "Laser" ("Lasers") of the Optics and Precision Mechanics Standards Committee (NAFuO) is responsible at DIN, the German Institute for Standardization e.
