Note:*The test cycle is as per 13 mode cycle on dynamometer.** The test should be as per Indian driving cycle with cold start.***The emissions of visible pollutants (smoke) shall not exceed the limit value to smoke density. When expressed as light absorption coefficient given below for various nominal flows when tested as constant speeds over full load. (As indicated at Annexure I).Cop Standards*10% relaxation in the standards for HC, CO and NOx would be given.**10% relaxation in the standards for CO and combined HC+NOx would be given.[Mass emission standard for petrol-driven vehicles-Effective from 1st April, 1998
