IS 16376 : 2025/ISO 21342 : 2019 Synchronous Belt Drives - Automotive Belts and Pulleys

ICS 21.220.10; 43.060.10

PGD 40

(Superseding IS 16377 : 2017)

NATIONAL FOREWORD

This Indian Standard (First Revision) which is identical to ISO 21342 : 2019 'Synchronous belt drives - Automotive belts and pulleys' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Conveyor Belts Sectional Committee and approval of the Production and General Engineering Division Council.

This standard specifies the characteristics of synchronous endless belts and their related pulleys for use in automotive applications such as engine camshaft drives.

This standard was first published in 2017. This revision has been brought out to align the standard with ISO 21342 : 2019. In this revision the requirement covered in two difference standards for automotive belts and pulleys have been merge into one standard. This standard supersedes IS 16377 : 2017.

In this standard the test methods for measuring belt pitch length and lateral run out have been included.

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.
