4、cember 2009. 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 by national legisl
5、ation. This standard has been prepared by Technical Committee CEN/TC 122 “Ergonomics” (Secretariat: DIN, Germany) in connection with the amended EC Machinery Directive. The responsible German bodies involved in its preparation were the Normenausschuss Ergonomie (Ergonomics Standards Committee) and t
6、he Normenausschuss Informationstechnik und Anwendungen (Information Technology and selected IT Applications Standards Committee), Joint Technical Committee NA 023-00-04 GA Ergonomie fr Informationsverarbeitungssysteme. This standard contains specifications meeting the essential requirements set out
7、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 commissioned within the EEA. This
8、 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 compliance with the require
9、ments of the Machinery Directive (“presumption of conformity”). Amendments This standard differs from DIN EN 894-3:2000-06 as follows: a) Annex ZA (informative) “Relationship between this European Standard and the Essential Requirements of EU Directive 98/37/EC” has been revised. b) Annex ZB (inform
10、ative) “Relationship between this European Standard and the Essential Requirements of EU Directive 2006/42/EC” has been added. Compared with DIN EN 894-3:2009-02, the following correction has been made to the German version only and therefore does not affect the English version: c) As Figure 7 shown
11、 on page 26 was the same as Figure 7 shown on page 25, the figure on page 26 has been deleted.

26、 control task in question and take account of the circumstances of their use. It applies to manual control actuators used in equipment for occupational and private use. It is particularly important to observe the recommendations in this European Standard where operating a control actuator may lead t
27、o injury or damage to health, either directly or as a result of a human error. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.

Each type is suited to part
37、icular task requirements and to certain operator capabilities. Environmental factors (e.g. illumination, vibration) and organisational factors (e.g. team work, workstation separation) also have to be considered. To ensure safe and efficient operation, correct selection of control actuators is import
38、ant. The following describes a systematic procedure that will enable designers and manufacturers to select manual control actuators meeting their specific requirements. The selection procedure involves three steps which are carried out in an iterative manner. These are: task evaluation and informati
39、on collection; intermediate selection of control families; identification of suitable control types. The main steps in the selection procedure are shown in figure 1. An example of a form for recording the results of the evaluation is shown in figure 2. Clause 5 describes the information that is requ
40、ired in order to select appropriate control actuators, clauses 6 and 7 then describe how this information is used in order to make the selection. 5 Task evaluation and information collection 5.1 Requirements and characteristics The division of tasks between the operator and the equipment should have
41、 been determined early in the design process in accordance with the recommendations in EN 614 -1 and EN 894 -1. There are general and specific requirements imposed by a task which normally cannot be changed. If it is not possible to find a suitable control actuator for a specified task then the allo
42、cation of this task or the task itself has to be reconsidered. The task requirements considered in this European Standard are ones that experience has shown to be most important in selecting manual control actuators, as follows: General task requirements a) Accuracy required in positioning the manua
43、l control actuator (accuracy); b) Speed of setting required (speed); c) Force/torque requirements (force). Specific task requirements d) Need for visual checking of manual control actuator setting (visual check); e) Need for tactile checking of setting (tactile check); f) Need to avoid inadvertent o
44、peration (inadvertent operate); g) Need to avoid hand slipping from manual control actuator (friction); DIN EN 894-3:2010-01 EN 894-3:2000+A1:2008 (E) 8 h) Need for operator to wear gloves (use with gloves); i) Need for easy cleaning (ease of cleaning). The general task requirements are used to iden
45、tify classes of suitable control actuators. The specific task requirements are used in selecting individual control actuators within these classes. In order to evaluate the task requirements the classification scheme illustrated in table 1 should be used. This differentiates between 5 different leve
46、ls from 0 to 4. Table 1 Classification scheme for evaluating task requirements CODE SYMBOL Degree of requirements 0 Negligible 1 Low 2 Average 3 High 4 Very high The task requirements do not need to be evaluated precisely, therefore the detailed evaluation procedure given in 5.2 and 5.3, show classi
47、fication systems that have been found to be sufficiently accurate. The characteristics of the various types of control actuator need to be considered to determine the available selection options. This standard gives information on both movement characteristics and grip characteristics. In many cases
48、 some of the characteristics will have been predetermined by the task requirements. Movement characteristics: j) Type of movement; k) Axis of movement; l) Direction of movement; m) Continuity of movement; n) Angle of rotation for continuous rotary movements 180 0 Grip characteristics: o) Type of gri
49、p; p) Part of hand applying force; q) Method of applying force. The above categories a - q are used throughout this standard.
