National Foreword

This Indian Standard (Part 34) which is identical with ISO 128-34 : 2001 ?Technical drawings -General principles of presentation - Part 34: Views on mechanical engineering drawings? issued byInternational Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards onthe recommendation of the Drawings Sectional Committee and approval of the Production and GeneralEngineering Division Council.

ISO 128 was published in 1982 and was accordingly adopted as IS 10714 : 1983. ISO 128 : 1982 waswithdrawn and published again in several parts. In view of this, Drawings Sectional Committee decidedto adopt ISO 128-.34 : 2001 as IS 10714 (Part 34).

This standard specifies rules for the presentation of views additional to those of ISO 128-30 andapplicable to mechanical engineering drawings that follow the orthographic projection methods specifiedin ISO 5456-2. Attention has also been given to reproduction requirements, including those of microcopyingaccording to ISO 6428.

The other parts of this series aregiven as follows:

IS 10714 (Part 20) : 2001 Technical drawings - General principles of presentation: Part 20 Basicconventions for lines

IS 10714 (Part 21) : 2001 Technical drawings - General primiples of presentation: Part 21 Preparationof lines by CAD systems

The text of ISO Standard has been approved as suitable for publication as an Indian Standard withoutdeviations. Certain conventions are, however, not identical to those used in Indian Standards. Attentionis particularly drawn to the following:

a) Wherever the words, ?International Standard? appear, referring to this standard, they should beread as ?Indian Standard?.

b) Comma ( , ) has been used as a decimal marker while in Indian Standards, the current practiceis to use a.point ( . ) as the decimal marker.

In this adopted standard, reference appears to certain International Standards for which Indian Standardsalso exist. The corresponding Indian Standards which are to be substituted in their places, are listedbelow along with their degree of equivalence for the editions indicated:
