National foreword This standard includes safety requirements within the meaning of the Gerte- und Produktsicherheitsgesetz (GPSG) (German Eq

4、uipment and Consumer Goods Safety Law) and in connection with European legislation (EC Machinery Directive), which has been implemented by national legislation. This standard has been prepared by Technical Committee CEN/TC 114 “Safety of Machinery” (Secretariat: DIN, Germany) in connection with the

5、amended EC Machinery Directive. The responsible German body involved in its preparation was the Normenausschuss Sicherheitstechnische Grundstze (Safety Design Principles Standards Committee), Joint Committee NA 095-01-04 GA Schutz-einrichtungen, Sicherheitsmanahmen und Verriegelungen. This standard

6、concretizes the basic requirements set out in Annex I of the EU Machinery Directive 98/37/EC (valid until 28 December 2009) and the new EU Machinery Directive 2006/42/EC which becomes applicable on 29 December 2009 relating to machinery to be placed on the EEA market, with the intent of simplifying

7、the means of proving conformity with such requirements. Once this standard is designated a harmonized standard in the Official Journal of the European Union, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (the so-called “presumption of co

8、nformity”). This standard makes reference to documents which were valid as of the publication of the European standard. Since then, the standards EN 292-1, EN 292-2 and EN 294 cited in clause 2 have been replaced by DIN EN ISO 12100-1, DIN EN ISO 12100-2 and DIN EN ISO 13857. Amendments This standar

23、on According to EN 292-1, in general, machinery is said to be safe if it can perform its function, be transported, installed, adjusted, maintained, dismantled and disposed of under the conditions of its intended use without causing injury or damaging health. One method of avoiding the hazard of crus

24、hing of parts of the human body is to make use of the minimum gaps in this standard. In specifying minimum gaps a number of aspects have to be taken into consideration, such as accessibility of the crushing zones; anthropometric data, taking into account ethnic groups likely to be found in European

25、countries; technical and practical aspects. If these aspects are further developed, the current state of the art, reflected in this European Standard, could be improved. 1 Scope The object of this European Standard is to enable the user (e.g. standard makers, designers of machinery) to avoid hazards

26、 from crushing zones. It specifies minimum gaps relative to parts of the human body and is applicable when adequate safety can be achieved by this method. This European Standard is applicable to risks from crushing hazards only and is not applicable to other possible hazards, e.g. impact, shearing,

27、drawing-in. NOTE For e.g. impact, shearing, drawing-in hazards, additional or other measures need to be taken 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places i

For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

31、s of the human body are exposed to a crushing hazard. This hazard will be generated if two movable parts are moving towards one another; one movable part is moving towards a fixed part. (see also Annex A) 4 Minimum gaps 4.1 Methodology for the use of this European Standard The method of using this E

32、uropean Standard shall form part of the iterative safety strategy outlined in clause 5 “Strategy for selecting safety measures“ of EN 292-1. The user of this European Standard shall: a) Identify the crushing hazards; b) Assess the risks from these hazards in accordance with EN 292-1 paying particula

33、r attention to the following; Where it is foreseeable that the risk from a crushing hazard involves different parts of the body, the minimum gap in table 1 relating to the largest of these parts shall be applied (see also d); The unpredictable behaviour of children and their body dimensions if child

34、ren are included in the population at risk; Whether parts of the body could enter the crushing zone in a configuration other than those indicated in Table 1; Whether thick or bulky clothing (e.g. protective clothing for extreme temperatures) or tools have to be taken into account; Whether machinery

35、will be used by persons wearing thick soled footwear (e.g. clogs) which will increase the effective dimension of the foot. c) Select from Table 1 the appropriate minimum gap relating to the body part at risk (see also Annex A). d) If adequate safety cannot be achieved by the minimum gaps selected fr

36、om table 1, other or additional measures and/or means shall be used (see e.g. EN 292-1, EN 292-2 and EN 294). If the minimum gap for the largest expected body part cannot be achieved, the following example gives one particular means of restricting access to smaller body parts. EXAMPLE Access of larg

37、er body parts to the crushing zone can be prevented by the use of protective structures having a restricted opening, as indicated in Figure 1. DIN EN 349:2008-09 EN 349:1993+A1:2008 (E) 6 The possibility of access to a crushing zone for a particular part of the body is dependent on the following: Th

38、e gap a between the fixed and moving part or between two moving parts; The depth b of the crushing zone; The dimensions c of the opening in the protective structure and its distance d from the crushing zone. NOTE The dimensions for openings in relation to safety distances can be found in EN 294. Key

39、 1 protective structure Figure 1 e) For certain applications there may be justifiable reasons to deviate from the minimum gaps in Table 1. Standards dealing with these applications shall indicate how adequate safety can be reached. 4.2 Values Table 1 gives values for minimum gaps to avoid crushing o

40、f parts of the human body. For the selection of the appropriate minimum gap see 4.1.
