8. The Conformity of Production (COP) testing procedure shall be as described
in section 7 of Annexure-I of EEC Directive 70/220/EEC (Refer Appendix
1 or Appendix 2 as applicable) last amended by 98/69/EC.
9. The COP frequency and samples:—
(i) The COP period for each vehicle model including its variants shall be
once in a year.
(ii) For production volume of less than 250 for six months, the method as
prescribed in the provisos to rule 126A shall apply.
10. The vehicles meeting the above norms shall use commercial fuel as per BIS
specification IS:1460-2000 (Amendment No. I - January, 2003) (Fourth
Revision) for Diesel and IS:2796-2000 (Amendment No. II-February, 2003)
(Third Revision) for Gasoline.
11. For the vehicles described in clauses (A), (B) and (C) of this sub-rule,
deterioration factor shall be as given below:
Engine category Deterioration factors
CO HC NOx HC+NOx PM
Gasoline/Gas Engine 1.2 1.2 1.2 — —
Diesel Engine 1.1 — 1.0 1.0 1.2
(i) Alternatively, the vehicle manufacturers may opt for an ageing test of
80,000 kms for evaluating deterioration factor, as described in
Annexure - VII of European Economic Community Directive
70/220/EEC last amended by 98/69/EC with the following
exceptions:
(a) The maximum lap speed at 10th lap will be 72 km/h
(b) The maximum lap speed at 11th lap will be 90 km/h
(ii) The above ageing test should be carried out by the approved test
agency.
12. For diesel vehicles, the emission of visible pollutants (smoke) shall not
exceed the limit value to smoke density, when expressed as light absorption
coefficient for various nominal flows as given in Annexure-I of sub-rule (9)
when tested at constant speeds over 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 of 0.98 to 1.02.
13. In case of diesel vehicles, the engine power shall be measured on engine
dynamometer and the measured power shall not differ from the specified
power as given below:
(i) For Type approval: ± 5% at maximum power point and ± 10% at other
measurement points for single cylinder engines ± 2% at maximum
power point and + 6% and -2% at other measurement points for all
other engines.
(ii) Testing procedures shall be in accordance with Chapter - 6 of Part IV
of the reference document MOST/CMVR/TAP-115/116, as amended
from time to time by the Government of India in the Ministry of
