NATIONAL FOREWORD

This Indian Standard which is identical with ISO 9249 : 2007 ‘Earth-moving machinery — Engine test code — Net power’ was issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Material Handling Systems and Equipment Sectional Committee and approval of the Mechanical Engineering Division Council (MEDC).

This standard supersedes IS 13116 : 2006 /ISO 9249 : 1997 Earth-moving machinery — Engine test code — Net power ( second revision ).

This Indian Standard is intended to be applied in conjunction with the ‘core’ standard ISO 15550, in order to define the net power ratings for earth-moving machinery, where relevant equipment and accessories that absorb engine power (fan, pump, air compressors and so forth), are deducted from the engine power rating.

The text of ISO Standard has been approved as suitable 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.
