20、, presentation.EN ISO 6284:1999 BSI 03-2000 iii Foreword ISO(the International Organization for Standardization) 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 mem

21、ber body interested in a subject for which a technical committee has been established has the right to be 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 El

22、ectrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least75% of the member bodies casting

23、 a vote. International Standard ISO6284 was prepared by Technical Committee ISO/TC10, Technical drawings, product definition and related documentation, Subcommittee SC8, Construction documentation. This second edition cancels and replaces the first edition(ISO6284:1985), which has been technically r

Annex A of this International Standard is for information only.iv blankEN ISO 6284:1999 BSI 03-2000 1 1 Scope This International Standard specifies methods for the indication of limit deviations on construction drawings. 2 Normative references The following standards contain provisions which

25、, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility o

ISO9431:1990, Construction drawings Spaces for drawing and for text, and title blocks on drawings sheets. 3 Definitions For the purposes of this International Standard, the definitions given in ISO28

28、6-1 and ISO1803 apply. 4 General A limit deviation shall be indicated on a drawing only when there is a functional requirement to control dimension, orientation or form. 5 Indication of limit deviations 5.1 The following methods shall be used when requirements for accuracy are to be defined by limit

29、 deviations. The indication of limit deviations shall be a) a single reference in the space for text(seeISO9431) in the case of repetitive deviations; b) placed with, or adjacent to, the caption of the figure when limit deviation information applies only to sizes within that figure(for example, a cr

30、oss-section detail); c) placed with, or adjacent to, the size concerned when limit deviation information applies only to that size. 5.2 Limit deviations for size shall be indicated by the target size and the limit deviations. The target size and the values of limit deviations shall be given in milli

31、metres(seeFigure 1 and Figure 2). In the case of angles, the target size and the limit deviations should preferably be given in degrees, but may be given, if necessary, in gon. Limit deviation information which is shown on drawings should be given in accordance with the example shown in Figure 1a) f

32、or a symmetrical limit deviation and in accordance with Figure 1 b) or Figure 1 c) for an asymmetrical limit deviation. 5.3 Limit deviations for a position dimension are limit deviations for a dimension which locates one item in relation to another, for example, one reference line to another, a comp

33、onent to a reference lineseeFigure 2 a) and ISO4068 or a finished floor level to a datum levelseeFigure 2 b). Levels relate to site zero datum and are given in metres with three digits to the right of the decimal sign. 1) To be published. (Revision of ISO1803-1:1985, ISO1803-2:1986 and ISO4464:1980)
