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 rep-
resented 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.
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 5456-l was prepared by Technical Committee
ISOfTC 10, Technical drawings, product definition and related documen-
tation, Subcommittee SC 1, Basic conventions.
IS0 5456 consists of the following parts, under the general title Technical
drawings - Projection methods:
- Part 7 : Synopsis
- Part 2: Orthographic representations
Part 3: Axonome tric representations
Part 4: Central projection

Introduction
In the broad field of technical activities, various projection methods are
used to represent objects. All these methods have their own merits, but
also their inherent disadvantages.
The normal technical drawing is often an orthogonal projection, in which
related representations of more than one view are utilized (see IS0 5456-Z)
to draw and completely define any object by means of carefully chosen
views, cuts and sections.
However, the execution of such two-dimensional representations requires
an understanding of both the projection method and its interpretation, so
that the observer will be able to synthesize the single views into a three-
dimensional object.
For many technical fields and their stages of development, however, it is
necessary to provide an easily understood picture to observers. Such
drawings, called pictorial representation, provide a three-dimensional view
of an object as it would appear to the observer. No special technical train-
ing for reading pictorial representations is necessary.
Pictorial representations ma presented on their own or may sup-
Y be
plement orthogonal drawings
exist, but their nomenclatures
Variou s methods of pictorial representations
differ, and may be used even contradictorily.
The steady increase in global technical intercommunication, as well as the
evolution of methods of computer-aided design and draughting with their
various types of three-dimensional representations, suggest the need for
ISOnC 10 to clarify this problem.
The rules and conventions given in IS0 5456 should be used, in accord-
ance with IS0 128, for all types of technical drawings and in all fields of
technical activities, such as:
- mechanical and construction drawings;
- manuals and instruction books;
- X-ray views;
- exploded views.
