Technical developments, leading to higher performance, higher efficiency, lower pollutions

with this approach can proper functioning be verified and the possibilities available for

This book presents the state of the art regarding geometrical dimensioning and tolerancing.
It describes the international standardization in this field, which is laid down
8 T; m, k: Y" |7 @" f; iin ISO Standards. It indicates the deviations between the American Standard ASME
3 s7 O* b: J& N+ S7 v! `, {Y14.5M, the former East European Standards and the ISO Standards. It describes the
. E }1 j0 l7 b. ]additional specifications laid down in the German Standards (DIN Standards). Possible
further developments in the field of geometrical tolerancing are also pointed out.
What has to be regarded for manufacturing within the geometrical dimensioning and
tolerances is explained.
Principles for the inspection of geometrical deviations are given, together with a
basis for tolerancing suitable for inspection.
- ^4 Y3 S! k# a3 ]Examples for tolerancing appropriate to various functional requirements, a guide for
geometrical tolerancing, are described.
" v9 n W) I" U+ q8 mThis book may serve as an introduction to geometrical dimensioning and tolerancing

The author has used his experiences gathered during the elaboration of the ISO
Standards and during his lectures and discussions on geometrical dimensioning and tolerancing

( s$ U6 x# u: T: u( d2 oand should be directed to the publisher.
9 S: G: L9 o- N8 ~6 \The book represents the author’s understanding of the various standards and is written
for educational purposes. In cases of dispute, the original standards have to be
considered. The functional cases of geometrical requirements vary over a wide range.

development in engineering. Future changes in standardization may make it necessary
to update some content of this book.

Georg Henzold was manager of the department for standardization of a manufacturer
( u/ j6 H- G- c; i. K$ H/ \of power plant machinery. He is chairman of the committee dealing with the standardization
in the field of geometrical dimensioning and tolerancing in the German
. \5 L9 k! x: m# A6 A nStandardization Institute (DIN), and he was the former chairman of the pertinent
European Committee for Standardization (CEN). He is a long-time delegate in the pertinent
committees of the International Standardization Organization (ISO).
