National Foreword

This Indian Standard (Part 40) which is identical with ISO 128-40 : 2001 ?Technical drawings -General principles of presentation - Part 40: Basic conventions for cuts and sections? issued by theInternational 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 128-40:2001 as IS 10714 (Part 40).

This standard specifies general principles for presenting cuts and sections applicable to all kinds oftechnical drawings (mechanical, electrical, architectural, civil engineering, etc), following the orthographicprojection methods specified in ISO 5456-2. For areas on cuts and sections, representation is accordingto ISO 128-50. The requirements of reproduction, including microcopying in accordance with ISO 6428has also been taken care of in this standard.

It is applicable for all kinds of technical drawings, imluding, for example, those used in mechanicalengineering and construction. It K applicable to both manual and computer-based drawings. !t is notapplicable to three-dimensional CAD models.

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 exists. The corresponding Indian Standards, which are to be substituted in their places, are listedbelow along with their degree of equivalence for the editions indicated:
