National foreword This standard includes safety requirements within the meaning of the Gerte- und Produktsicherheitsgesetz (GPSG) (German Equipment and Product Safety Act) and in connection with European legislation (EC Machinery Directive), which has been implemented

5、 by national legislation. This standard has been prepared by Technical Committee ISO/TC 159 “Ergonomics” in collaboration with Technical Committee CEN/TC 122 “Ergonomics” (Secretariat: DIN, Germany), taking into account the new revised EU Machinery Directive. The responsible German bodies involved i

6、n its preparation were the Normenausschuss Ergonomie (Ergonomics Standards Committee) and the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Joint Technical Committee NA 023-00-03 GA Anthropometrie und Biomechanik. This standard contains specifications meeting the essenti

7、al requirements set out in Annex I of the “Machinery Directive”, 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 commissio

8、ned within the EEA. This standard serves to facilitate proof of 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 com

9、pliance with the requirements of the Machinery Directive (“presumption of conformity”). Amendments This standard differs from DIN EN ISO 14738:2005-03 as follows: a) Inclusion of Annex ZB (informative) “Relationship between this European Standard and the Essential Requirements of EU Directive 2006/4

10、2/EC”. Compared with DIN EN ISO 4738:2008-12, the following correction has been made to the German version only and therefore does not affect the English text: a) Table ZB.1 of Annex ZB has been corrected.

32、kingsurface height means the height of the supporting level. The working height should be chosen to provide anadequate posture for the body and at the same time fulfil visual needs. The choice is a compromise betweendemands on low load on the neck, arms, shoulders and back and demands on viewing dis
