30、ation 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 be represented on that commit

31、tee. 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 Standards are drafted in accordanc

32、e 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 International Standard requires a

33、pproval 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. ISO 9493 was prepared by Technical Comm

35、 ISO/TR 14638). It influences the chain link 5 of the chains of standards on size, distance, form of a line independent of datum, form of a line dependent of datum, form of a surface independent of datum, form of a surface independent of datum, orientation, location, circular run-out and total run-o

44、e requirements of this International Standard under all orientations of operation. 4.1.2 Dial test indicators indicate displacement in a direction normal to the axis of the stylus, and in the same plane as the rotational direction of the stylus, unless otherwise stated. See Figure D.1 as an example.

45、 If used at some other angle, a correction shall be made (see Annex D). 4.1.3 Dial test indicators shall be capable of measuring when the stylus is displaced in either direction from its rest position. NOTE Some dial test indicators have the ability to measure in both directions without external adj

46、ustments and some dial test indicators are provided with a bias lever to change the measuring direction. 4.2 Type Dial test indicators are commonly manufactured in three types see Figure 1 a), b) and c). These types have the following names. Type S, Standard, where the dial face is mounted on the bo

47、dy of the dial test indicator, in a plane perpendicular to the plane in which the stylus moves. Type H, Horizontal, where the dial face is mounted on the body of the dial test indicator, in a plane parallel to the plane in which the stylus moves. Type V, Vertical, where the dial face is mounted at t

48、he end of the dial test indicator opposite that of the stylus. NOTE Although less common, configurations of dial test indicators, which do not fall into the above three categories, exist. The above-mentioned list of three named types includes those that are the most common. BS EN ISO 9493:2010ISO 94
