ISO/TC 172/SC 9/JWG 3 - Joint ISO/TC 172/SC 9-IEC/TC 76 WG: Safety

This document describes laser radiation hazards arising in laser processing machines, as defined in 3.7. It also specifies the safety requirements relating to laser radiation hazards, as well as the information to be supplied by the manufacturers of such equipment (in addition to that prescribed by IEC 60825). Requirements dealing with noise as a hazard from laser processing machines are included in ISO 11553‑3:2013. This document 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 60601-2-22); — data storage.

ISO/IEC 11553-3:2013 describes the requirements to deal with noise hazards and specifies all the information necessary to carry out efficiently and under standardized conditions the determination, declaration and verification of airborne noise emission from laser processing machines and hand-held laser processing devices within the scope of ISO/IEC 11553-1 and ISO/IEC 11553-2. It specifies the safety requirements relating to noise hazards. It specifies noise measurement methods, installation and operating conditions to be used for the test, together with the information to be supplied by manufacturers of such equipment. ISO/IEC 11553-3:2013 applies to those laser processing machines and hand-held laser processing devices included in the scope of ISO/IEC 11553-1 and ISO/IEC 11553-2. Noise emission characteristics include emission sound pressure levels at work stations and the sound power level. Declared noise emission values permit comparison of laser processing machines and hand-held laser processing devices on the market. The use of this noise test code (see Annex A) ensures the reproducibility of the determination of the characteristic noise emission values within specific limits. These limits are determined by the accuracy grade of the noise emission measuring method used. Noise emission measurements specified by ISO/IEC 11553-3:2013 meet the requirements of an engineering method (accuracy grade 2).

ISO 11553-2:2007 specifies the requirements for laser processing devices, as defined in ISO 11553-1, which are hand-held or hand-operated. The purpose of ISO 11553-2:2007 is to draw attention to the particular hazards related to the use of hand-held laser and hand-operated laser processing devices and to prevent personal injury. This includes both the areas of hazard analysis and risk assessment as well as protective measures.

ISO 11553-1:2005 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 the manufacturers of such equipment. Requirements dealing with noise as a hazard from laser processing machines are not included in ISO 11553-1:2005. They will be included in a subsequent amendment. ISO 11553-1:2005 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 and data storage.

Describes hazards generated by laser processing machines and specifies the safety requirements to avoid hazards caused by radiation.
