General Information
Frequently Asked Questions
JWG 10 is a Technical Committee within the International Electrotechnical Commission (IEC). It is named "TC 76/JWG 10". This committee has published 70 standards.
JWG 10 develops IEC standards in the area of Information technology. Currently, there are 70 published standards from this technical committee.
The International Electrotechnical Commission (IEC) is the world's leading organization for the preparation and publication of international standards for electrical, electronic, and related technologies. Founded in 1906, the IEC provides a global platform for companies, industries, and governments to meet, discuss, and develop the international standards they require.
A Technical Committee (TC) in IEC is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
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).
