National Foreword

This Indian Standard (Part 30) which is identical with ISO 128-30 : 2001 ?Technical drawings -General principles of presentation - Part 30 : Basic conventions for views? issued by the InternationalOrganization for Standardization (ISO) was adopted by the Bureau of Indian Standards on therecommendation 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 128-30 : 2001 as IS 10714 (Part 30).
