Revised Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 1) (Second Revision) which is identical with ISO 2710-1 : 2017 ‘Reciprocating internal combustion engines — Vocabulary — Part 1: Terms for engine design and operation’ issued by International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendations of the Automotive Prime Movers Transmission Systems and Internal Combustion Engines Sectional Committee and after approval of the Transport Engineering Division Council.

This standard was originally published in 1974 and subsequently revised in 2007. First revision of this standard was identical with ISO 2710-1 : 2000. The second revision of this standard has been undertaken to align it with ISO 2710-1 : 2017.

The major change in this revision are as follows:

a) New terms and definitions have been added.

b) Terms and definitions in ISO 2710‑1 : 2000 which are no longer used have been deleted. This Indian Standard is published in several parts. The other parts in this series are:

Part 2 Designation of the direction of rotation and of cylinders and valves in cylinder heads, and definition of right-hand and left-hand in-line engines and locations on an engine (first revision) (Amalgamating Part 3, 4 and 5)

Part 6 Hand-operated control devices — Standard direction of motion

The text of ISO Standard has been approved for publication as an Indian Standard without deviations. Certain terminologies and 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.

Attention is drawn to the possibility that some of the elements of this standard may be the subject of patent rights. The Bureau of Indian Standards shall not be held responsible for identifying any or all such patent rights.
