IS 2403 : 2024/ISO 606 : 2015 Short-Pitch Transmission Precision Roller and Bush Chains, Attachments and Associated Chain Sprockets
NATIONAL FOREWORD
This Indian Standard (Fourth Revision) which is identical to ISO 606 : 2015 'Short-pitch transmission precision roller and bush chains, attachments and associated chain sprockets' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Transmission Devices Sectional Committee and approval of the Production and General Engineering Division Council.
This standard was first published in 1964. The first, second and third revisions of this standard were published in 1975, 1991 and 2014 respectively. This revision has been undertaken to align it with ISO 606 : 2015.
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'; and
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.
