4、until 28 December 2009. National foreword This standard includes safety requirements. This standard has been prepared by Technical Committee ISO/TC 172 “Optics and photonics” in collaboration with Technical Committee CEN/TC 123 “Lasers and photonics” (Secretariat: DIN, Germany). The responsible Germ
5、an body involved in its preparation was the Normenausschuss Feinmechanik und Optik (Optics and Precision Mechanics Standards Committee), Technical Committee NA 027-01-18 AA Laser. This standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”
6、, Directive 98/37/EC, (valid until 28 December 2009) and the “revised Machinery Directive”, Directive 2006/42/EC, which takes effect on 29 December 2009, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of
7、 compliance with the essential requirements of the directives. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“pres
8、umption of conformity”).

EN ISO 11553-2:2008 (E) 3DIN EN ISO 11553-2:2009-03 Introduction This document is a type C standard as stated in ISO 12100-1:2003. The machinery concerned and the extent to which hazards, hazardous situations an
34、d events are covered are indicated in the scope of this document. When provisions of this type C standard 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
35、 designed and built according to the provisions of this type C standard. It is applicable to machines 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 specifyi
36、ng safety measures and verifications necessary for reducing the risk caused by specific hazardous 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. EN ISO 11553-
37、2:2008 (E) 4DIN EN ISO 11553-2:2009-03 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 ISO 11553 is to draw attention to the particular hazards related to the use of h
38、and-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 as a hazard are not included in this part of ISO 11553. These requirements are t
39、o 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 Normative references The following referenced documents are indispensable for the applic

47、evice in which a laser provides sufficient energy/power to melt, evaporate or cause a phase transition in a part of the workpiece and where the laser output or workpiece to be processed is guided manually or hand-held during the laser process NOTE For the purposes of this document, the terms “hand-h
48、eld” and “hand-operated” have the same meaning. 3.2 confined spaces working areas surrounded on all sides, or for the most part, by solid walls where they, on account of their confinement or containment of materials, preparation or equipment, augment or can augment particular hazards that considerab
49、ly exceed the hazard potential normally prevailing at workplaces 3.3 supply unit all devices that provide the process energies and operating material supply, direct these energies to the point of action and are absolutely necessary for the operation of the hand-held laser processing device (e.g. cooling system, power and gas supply) 3.4 disposal units equipment that captures and removes effluents and by-products d
