Sectional Committee, TED 2

NATIONAL FOREWORD IThis Indian Standard which is identical with ISO 2710-2: 19!39 ‘Reciprocating internal combustion engines— Vocabulary — Part 2: Terms for engine maintenance’ issued by the International Organization forStandardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of theAutomotive Primemovers Transmissions, Steering Systems and Internal Combustion Engines SectionalCommittee and approval of the Transport Engineering Division Council.

The sectional committee decided to align the Indian Standard with the corresponding InternationalStandard wherever feasible and wherever the domestic considerations were not so intense so as tohave standards different from the ISO Standards. This decision was taken with a view to upgrade-thequality of the products in line with the International Standards.

The text of the IS-O Standard has been approved as suitable for publication as an Indian Standardwithout deviations. Certain conventions are, however, not identical to those used in Indian Standards.Attention is particularly drawn to the following: I

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

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