IS 11715 : PART 1 : 2011 : Aerospace - Lead And Runout Threads Part 1 Rolled External Threads

NATIONAL FOREWORD

This Indian Standard (Part 1) (First Revision) which is identical with ISO 3353-1 : 2002 ‘Aerospace - Lead and runout threads - Part 1: Rolled external threads’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Aircraft, Space Vehicles, Air Cargo Handling and Aircraft Electrical Equipment Sectional Committee and approval of the Transport Engineering Division Council.

This standard was first published in 1986 by adopting ISO 3353 : 1976 ‘Rolled threads for aerospace fasteners’. This standard has been undertaken with a view to bring it in line with the latest version of ISO 3353 published in two parts.

This standard is also published in two parts. Other part is: Part 2 Internal threads

The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

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