23、-3:2013ISO 11553-3:2013(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested i
24、n a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commis
25、sion (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical c
26、ommittees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall no

30、 machinery is safe. In response, CEN/CENELEC initiated a programme to produce safety standards for machines and their applications. This part of ISO/IEC 11553 is one in that series. It has been prepared as a harmonized standard to provide a means of conforming with the essential safety requirements
31、of the Machinery Directive and associated EFTA Regulations.This document is a type B standard as stated in ISO 12100. The provision of this document may be supplemented or modified by a type C standard.For machines which are covered by the scope of a type C standard and which have been designed and
32、built according to the provision of that standard, the provisions of that type C standard take precedence over the provisions of this type B standard.It is applicable to machines using laser radiation to process materials. The purpose of this part of ISO/IEC 11553 is to prevent injuries to persons b
33、y listing potential hazards generated by machines containing lasers, specifying safety measures and verifications necessary for reducing the risk caused by specific hazardous conditions, providing references to pertinent standards, and specifying the information which is to be supplied to the users
34、so that they can establish proper procedures and precautions.

36、ne 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 fo
37、r the test, together with the information to be supplied by manufacturers of such equipment.This part of ISO/IEC 11553 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
38、 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 determinatio
39、n 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 this part of ISO/IEC 11553 meet the requirements of an engineering method (accuracy grade 2).2
