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 5456-2 was prepared by Technical Committee
lSO/TC 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
Orthographic representation in its various forms is the most widely used
method of representing technical objects in all fields of technical drawing
(mechanical, electrical, construction, etc.), and is thus considered to be the
accepted technical language.
