27、cument (EN 1005-5:2007) has been prepared by Technical Committee CEN/TC 122 “Ergonomics”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by August 2007, and
28、conflicting national standards shall be withdrawn at the latest by August 2007. As a result of the assessment of the CEN consultant the standard will be published a non-harmonized standard (no reference to Machinery directive and no publication in the Official Journal of EC). EN 1005 consists of the

EN 1005-5:2007 (E) 5 Introduction Within the life cycle of a machine from construction to dismantling, various machine-related actions may require repetitive handling at high frequency. Repetitive handling at high frequency can cause mus
33、culoskeletal strain and the risk of fatigue, discomfort and musculoskeletal disorders. The designer of a machine should seek to minimise these health risks by taking into account a variety of risk factors including the frequency of actions, the force, postures, durations, lack of recovery and other
34、additional factors. NOTE 1 Although factors such as duration and lack of recovery periods are relevant factors when assessing risk in relation to human physical performance in the workplace, these factors are controlled by the member states own national legislation, contract agreements with social p
35、artners and are not in the scope of this European Standard. The risk assessment method in this European Standard gives guidance to the designer how to reduce health risks for the operator. This European Standard is written in conformity with EN ISO 12100-1 and provides the user with guidance for haz
36、ard identification for harm through musculoskeletal overload and tools for qualitative and, to an extent, a quantitative risk assessment. The risk assessment tools also indicate how to achieve risk reduction. This European Standard does not deal with risks related to accidents. The recommendations p
37、rovided by this European Standard are based on available scientific evidence concerning the physiology and epidemiology of manual work. The knowledge is, however, limited and the suggested guidelines are subject to changes according to future research. This European Standard is a type B standard as
38、stated in EN ISO 12100-1. The provisions of this European Standard can be supplemented or modified by a type C standard. NOTE 2 For machines which are covered by the scope of a type C standard and which have been designed and built according to the provisions of that standard, the provisions of that
39、 type C standard take precedence over the provisions of this type B standard. EN 1005-5:2007 (E) 6 1 Scope This European Standard presents guidance to the designer of machinery or its component parts and the writer of type C standards in assessing and controlling health and safety risks due to machi
40、ne-related repetitive handling at high frequency. This European Standard specifies reference data for action frequency of the upper limbs during machinery operation, and it presents a risk assessment method intended for risk reduction option analysis. This European Standard applies to machinery for
41、professional operation by the healthy adult working population. This European Standard is not applicable for repetitive movements and related risks of the neck, back and lower limbs. 2 Normative references The following referenced documents are indispensable for the application of this document.
