178 THE CENTRAL MOTOR VEHICLES RULES, 1989 RULE 115

6. There shall be no crankcase emissions for Gasoline driven vehicles.
7. Evaporative emission shall not be more than 2.0 g/test from Gasoline driven
vehicles. The evaporative emission test procedure for gasoline driven
vehicles shall be as per the procedure specified in MoSRTH/CMVR/
TAP-115/116 and as amended from time to time.
8. The Conformity of Production (COP) testing procedure shall be as described
in MoSRTH/CMVR/TAP-115/116, as amended from time to time.
9. The COP frequency and samples:
(i) The Conformity of Production period for each vehicle model including
its variant(s) shall be once in a year;
(ii) Where production volume in six months is less than 250 per model
including its variants, the provisions contained in the provisos to rule
126-A shall apply.
10. The commercial Gasoline and Diesel fuel shall be as per Annexures IV-N
and IV-O in respect of the places mentioned in clause (a) of this sub-rule
and in respect of all other places, the commercial fuel shall be Bharat
Stage-III as per BIS specification IS:1460-2005 (Fifth Revision) for Diesel and
IS:2796-2008 (Amendment No. 1-January 2008) (Fourth Revision) for
Gasoline. Specification for commercial CNG and LPG shall be as notified
from time to time.
11. For the vehicles of the Category M and Category N with Gross Vehicle
Weight not exceeding 3,500 kg.—
(i) Deterioration factor shall be as given below:

Engine Category Deterioration Factor
CO HC NOx HC+NOx PM
Gasoline/Gaseous fuelled engines 1.2 1.2 1.2 Not Applicable
Diesel Engines 1.1 Not 1.0 1.0 1.2
Applicable
(ii) Alternatively, the vehicle manufacturers may opt for an ageing test of
80,000 km for evaluating deterioration factor as per
MoSRTH/CMVR/TAP-115/116 and as amended from time to time.
(iii) The maximum lap speed at 10th lap and at 11th lap shall be 72
km/hour and 90 km/hour respectively.
(iv) The above ageing test should be carried out by the approved test
agency specified in rule 126.
12. For Diesel vehicles, the emission of visible pollutants (smoke) shall not
exceed the limit value of smoke density, when expressed as light absorption
coefficient for various nominal flows as given in Annexure I to sub-rule (9)
of rule 115 when tested at constant speeds over the full load. These smoke
limits are without correction factor and engines are to be tested with
conditioned air supplied to the engine to maintain atmospheric factor at
0.98 to 1.02.
