10、s a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represe
11、nted on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are d
12、rafted in accordance with the rules given in ISO/IEC Directives, Part 3. 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.
13、International Standard IS0 128-23 was prepared by Technical Committee ISOTTC 1 O, Technical drawings, product definition and related documentation, Subcommittee SC 8, Construction documentation. This first edition is based on IS0 128:1982, clause 3, and it replaces the rules specified in that clause
14、. IS0 128 consists of the following paris, under the general title Technical drawings - General principles of presentation: - Part 20: Basic conventions for lines - Part 21 : Preparation of lines by CAD systems - Part 22: Basic conventions and applications for leader lines and reference lines - Part
15、 23: Lines on construction drawings - Part 24: Lines on mechanical engineering drawings - Part 25: Lines on shipbuilding drawings - Part 30: Basic convention for views - Part 50: Basic conventions for representing areas on cuts and sections NOTE application of lines within drawings of various techni
16、cal fields. Annex A of this pari of IS0 128 is for information only. Further parts of IS0 128 are planned, covering other general principles of presentation including those for Introduction The basic conventions and the application of lines in respect to other fields of drawing practice are presente
17、d in other parts of IS0 128 since requirements in industry vary considerably. For further information, see IS0 128-20. Page 3 IS0 128-23 : 1999 1 Scope This part of IS0 128 specifies types of lines and their application in construction documentation comprising architectural drawings, structural engi
18、neering drawings, building service engineering drawings, civil engineering drawings, landscape drawings and town planning drawings. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of IS0 128. For da
19、ted references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of IS0 128 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated r
20、eferences, the latest edition of the normative document referred to applies. Members of IS0 and IEC maintain registers of currently valid international Standards.

The proportions between the line widths are 1 :2:4. A special line width is used for representation and lettering of graphic
39、al symbols. This line width is situated between the width of the narrow and the wide line.
