Foreword
IS0 (the International Organization for Standardization) is 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
represented 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
(I EC) 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.
International Standard IS0 128-20 was prepared by Technical Committee
ISOfTC 10, Technical drawings, product definition and related documen-
tation, Subcommittee SC 1, Basic conventions.
This first edition is based on IS0 128:1982, clause 3, and it replaces the
rules specified in that clause.
IS0 128 consists of the following parts, under the general title Technical
drawings - General principles of presentation:
- Part 20: Basic conventions for lines
- Part 2 7: Preparation of lines by CAD systems
- Part 23: Lines on construction drawings
Further parts of IS0 128 are planned, covering other general principles of
presentation including those for the application of lines within drawings
of various technical fields.
Annex A of this part of IS0 128 is for information only.

Introduction
IS0 128-20 was prepared as lSO/DlS 1201 l-l.
IS0 128-20 contains generally applicable rules for the presentation of lines
in all kinds of technical product documentation.
The application of lines within drawings of special technical fields varies
considerably. Therefore rules of application are not given in this part of
IS0 128.
Other International Standards containing rules for lines in specialized fields
are listed in annex A.

Technical drawings - General principles of
presentation -
Part 20:
Basic conventions for lines
1 Scope
This part of IS0 128 establishes the types of lines, their designations and their configurations, as well as general
rules for draughting of lines used in technical drawings, e.g. diagrams, plans or maps.
2 Definitions
For the purposes of this part of IS0 128, the following definitions apply.
2.1 line: Geometrical object, the length of which is more than half of the line width and which connects an origin
with an end in any way, e.g. straight, curved, without or with interruptions.
NOTES
1 The origin and the end may coincide with one another, e.g. in the case of a line forming a circle.
2 A line, the length of which is less than or equal to half of the line width, is called a dot.
3 A test should be made in order to check the appearance of drawings intended to be microcopied or transferred by fax.
2.2 line element: Single part of a non-continuous line, e.g. dots, dashes, which vary in length, and gaps.
2.3 line segment: Group of two or more different line elements which form a non-continuous line, e.g. long
dash/gap/dot/gap/dot/gap.
