NATIONAL FOREWORD

This Indian Standard which is identical with ISO 9633:2001 ‘Cycle chains — Characteristics and test methods’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendations of the Transmission Devices Sectional Committee and approval of the Basic and Production Engineering Division Council.

The text of the 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.
