23、 BSI EN ISO 6284:1999 BSI 03-2000iii 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 member body
24、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 Electrotech
25、nical 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 least 75 % of the member bodies casting a vote
26、. International Standard ISO 6284 was prepared by Technical Committee ISO/TC 10, Technical drawings, product definition and related documentation, Subcommittee SC 8, Construction documentation. This second edition cancels and replaces the first edition (ISO 6284:1985), which has been technically rev
27、ised. Annex A of this International Standard is for information only.

29、 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 of applying the most recent editions of the standards listed below. Members of IEC and I
30、SO maintain registers of currently valid International Standards. ISO 286-1:1988, ISO system of limits and fits Part 1: Bases of tolerances, deviations and fits.

ISO 9431:1990, 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 ISO 286-1 and ISO 1803 apply. 4 General A limit deviation shall be indicated on a drawing
32、 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 deviations. The indication of limit deviations shall be a) a single reference in
33、the space for text (see ISO 9431) 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 cross-section detail); c) placed with, or adjacent to, the size concerned when l
34、imit 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 millimetres (see Figure 1 and Figure 2). In the case of angles, the target size and
35、 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 1 a) for a symmetrical limit deviation and in accordance with Figure 1 b) or Figu
36、re 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 component to a reference line see Figure 2 a) and ISO 4068 or a finished floor
37、level to a datum level see Figure 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.
