11、zation) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to b

12、e represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standa

13、rds are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Inter

14、national Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

15、was prepared by Technical Committee ISO/TC 159, Ergonomics, Subcommittee SC 4, Ergonomics of human-system interaction.

17、s SAFETY PRECAUTIONS It is particularly important that the provisions of this part of ISO 9355 be observed wherever the operation of a control actuator could lead to injury or damage to health, either directly or as a result of human error. 1 Scope This part of ISO 9355 gives ergonomic requirements

18、for, and guidance on, the selection, design and location of control actuators adapted to the needs of the operator, suitable for the control task in question and taking account of the circumstances of their use. It is applicable to manual control actuators used in equipment for both occupational and

19、 private use. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

25、ntrol actuators are available from push-buttons to hand wheels. Each type is suited to particular task requirements and certain operator capabilities. Environmental factors (e.g. illumination, vibration) and organizational factors (e.g. team work, workstation separation) also have to be considered.

26、To ensure safe and efficient operation, the correct selection of control actuators is most important. The following clauses specify a systematic selection procedure that will enable designers and manufacturers to select manual control actuators to meet their specific requirements. Clause 5 describes

27、 the information required for selecting appropriate control actuators; Clauses 6 and 7 then specify how this information is to be used in order to make the selection. The selection procedure involves three main steps, carried out in an iterative manner: task evaluation and information collection (Cl

28、ause 5); intermediate selection of control families (Clause 6); identification of suitable control types (Clause 7). Figure 1 shows the selection procedure overall.

29、 ISO 2006 All rights reserved5 Task evaluation and information collection 5.1 Task requirements and characteristics The division of tasks between the operator and the equipment should have been determined early in the design process according to the recommendations given in EN 614-1 and ISO 9355-1.

30、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 allocation of this task or the task itself has to be reconsidered. The task requirements considered in this Interna

31、tional Standard are ones that experience has shown to be the most important in selecting manual control actuators. They are as follows. General task requirements: a) accuracy required in positioning the manual control actuator (accuracy); b) speed of setting required (speed); c) force/torque require

32、ments (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 operation (inadvertent operation); g) need to avoid hand slipping from manual control actuat

33、or (friction); 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 identify classes of suitable control actuators. The specific task requirements are used in selecting individual control actuators within these

34、 classes. In evaluating the task requirements, the classification scheme according to Table 1 should be used. This differentiates between five different levels, from 0 to 4. Table 1 Classification scheme for evaluating task requirements Code Symbol Degree of requirements 0 Negligible 1 Low 2 Average

35、 3 High 4 Very high ISO 9355-3:2006(E) ISO 2006 All rights reserved 5 The task requirements do not need to be evaluated precisely; therefore, the detailed evaluation procedure given in 5.2 and 5.3 presents classification systems that have been found to be sufficiently accurate. The characteristics o

36、f the various types of control actuator need to be considered, in order to determine the available selection options. This part of ISO 9355 gives information on both movement characteristics and grip characteristics. In many cases, some of these characteristics will have been predetermined by the ta

37、sk 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. Grip characteristics: o) type of grip; p) part of hand applying force; q) method of applying force. The

38、above categories, a) to q), are used throughout this part of ISO 9355. NOTE The shorter descriptions given between parentheses for the task requirements a) to i) are used in table headings where space is limited.

44、 with Table 1. The accuracy required in the operation of a manual control actuator is determined by the task that has to be performed. Accuracy is influenced by a number of factors, the most important of which is continuity of movement required, i.e. whether action of a manual control actuator takes

45、 place in discrete steps or continuously. Adequate feedback of information to the operator is necessary to minimize mistakes in positioning. High accuracy is inconsistent with high force application and the selection procedure takes this into account. Thus, a requirement for high force and high accu

46、racy together will not lead to the successful selection of a suitable manual control actuator. Where control actuators are used frequently or for long durations, accuracy requirements are increased. Accuracy in positioning relates to the accuracy of positioning a manual control actuator itself. Accu

47、racy in the positioning of the controlled component may be increased by mechanical means, e.g. gears. In this case, a high accuracy of positioning of the controlled component can be achieved by use of a manual control actuator capable of only low accuracy. 5.2.1.1 Discrete manual control actuator mo

48、vements A discrete manual control actuator movement is one where the manual control actuator can only be moved to a number of fixed positions e.g. rotary switch, on/off switch. The error in selecting the correct position increases with the number of discrete positions. Thus, two positions shall be r

49、ated as “negligible” requirements, while 24 positions shall be rated as “high” requirements. Manual control actuators with more than 24 discrete positions should be avoided. Accuracy can be improved by, for example, feedback to the operator of information on the current value of the controlled variable, by clear labelling of manual control actuator positions, and/or by placing the manual control actuator where it can be easily seen and moved. For manual
