Technical developments, leading to higher performance, higher efficiency, lower pollutions
and greater reliability, and the constraints imposed by economy and the need for
rationalization, greater cooperation with licensees and subcontractors, make it necessary
to have completely toleranced drawings suitable for the function, for manufacturing

. g! f( y9 t' W& @6 C“Completely toleranced” means that the geometries (form, size, orientation and location)
of geometrical elements of the workpiece are completely defined and toleranced.
Nothing shall be left to the individual judgement of the manufacturer or inspector. Only
with this approach can proper functioning be verified and the possibilities available for
economization and rationalization in manufacturing and inspection be fully utilized.
This book presents the state of the art regarding geometrical dimensioning and tolerancing.
; |6 E; N% s$ ]) E6 G3 k- c5 ZIt describes the international standardization in this field, which is laid down
2 v& c$ l8 T* J7 b8 ]in ISO Standards. It indicates the deviations between the American Standard ASME
+ z7 Q* W: C" hY14.5M, the former East European Standards and the ISO Standards. It describes the

further developments in the field of geometrical tolerancing are also pointed out.

Principles for the inspection of geometrical deviations are given, together with a
basis for tolerancing suitable for inspection.
$ e% o- k( o, o+ mExamples for tolerancing appropriate to various functional requirements, a guide for

This book may serve as an introduction to geometrical dimensioning and tolerancing
/ `6 n1 g6 y8 b" kfor students, and may also help practitioners in the fields of design, manufacturing
and inspection.
4 Y# B3 Q% `$ A) [The author has used his experiences gathered during the elaboration of the ISO
- w& y( h: L% [/ _9 |Standards and during his lectures and discussions on geometrical dimensioning and tolerancing
in industry and education. However, proposals for improvements are appreciated
and should be directed to the publisher.
$ p# o& Z, r; s  F7 M2 |The book represents the author’s understanding of the various standards and is written
+ V% V* Y7 Y: l/ q2 Yfor educational purposes. In cases of dispute, the original standards have to be
considered. The functional cases of geometrical requirements vary over a wide range.
Therefore, before application in practice, it should be checked whether the presentation
in the book fits the particular purpose in the practical case.
