27、ederation 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 in a subject for which a technical committee has been established has the right to be represented on that co
28、mmittee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accor
29、dance 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 committees are circulated to the member bodies for voting. Publication as an International Standard requir
30、es 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 not be held responsible for identifying any or all such patent rights. ISO 11553-2 was prepared by Technic
31、al Committee ISO/TC 172, Optics and photonics, Subcommittee SC 9, Electro-optical systems. This first edition, together with ISO 11553-1, cancels and replaces ISO 11553:1996, which has been technically revised. ISO 11553 consists of the following parts, under the general title Safety of machinery La

The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this document. When provisions of this type C s
34、tandard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. It is applicable to machi
35、nes using laser radiation to process materials. The purpose of this part of ISO 11553 is to prevent injuries to persons: by listing potential hazards generated by machines containing lasers; by specifying safety measures and verifications necessary for reducing the risk caused by specific hazardous
36、conditions; by providing references to pertinent standards; by specifying the information which is to be supplied to the users so that they can establish proper procedures and precautions.

37、rved 1Safety of machinery Laser processing machines Part 2: Safety requirements for hand-held laser processing devices 1 Scope This part of ISO 11553 specifies the requirements for laser processing devices, as defined in ISO 11553-1, which are hand-held or hand-operated. The purpose of this part of
38、ISO 11553 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. Requirements concerning noise
39、as a hazard are not included in this part of ISO 11553. These requirements are to be included in a subsequent amendment. This part of ISO 11553 does not apply to laser products or equipment manufactured solely or expressly for applications which are excluded from the scope of ISO 11553-1. 2 Normativ
