(b) As an alternative to use a service accumulation schedule to determine
deterioration factors, engine manufacturers may select to use the
assigned multiplicative deterioration factors as per Table 5 given
below
TABLE 5
Test cycle CO HC NOx PM
NRSC 1.3 1.3 1.15 1.05
NRTC 1.3 1.3 1.15 1.05

(viii) Conformity of Production (COP) frequency and selection procedure
shall be as per procedure laid down in AIS:137 and as amended time
to time.
(ix) For Conformity of Production (COP),—
(a) for construction equipment vehicle with annual production or
Import up to 200 nos (per engine family), it shall be once in two
years per family or model.
(b) for construction equipment vehicle with annual production or
Import exceeding 200 nos (per engine family), it shall be once in
every year per family or model.
(x) For Conformity of Production (COP), the sampling size shall be one
day’s average production subject to a minimum of 10 and maximum
of 100:
PROVIDED that for engine family produced less than 200 in the yearly
period sample size may be one.
(xi) For Type approval and Conformity of Production (COP) test, fuel shall
be Reference fuel or commercial fuel as specified in Annexure IV-T and
Annexure IV-V of sub-rule (18) of rule 115.
(xii) The vehicles specified in this rule fitted with engine, which rely on the
use of a reagent in order to reduce emissions, shall ensure the correct
operation of NOx control measures, as per procedure laid down in
AIS:137 and as amended from time to time.
(xiii) Emission of ammonia over the Non-road transient cycle (NRTC) and
non-road steady cycle (NRSC) for engines equipped with SCR
(selective catalytic reduction) shall not exceed a mean value of 25 ppm
for engine power category less than or equal to 56 kW and 10 ppm for
engine power category above 56 kW.
(xiv) The diesel engine NOx reduction agent AUS: 32 (Aqueous Urea
Solution) shall conform to part 1 and part 2 of ISO: 22241.
(xv) The vehicles specified under this rule and manufactured after the 1st
April 2026 shall be monitored for gaseous pollutant emission from
in-service internal combustion engines installed on vehicles, as per
procedure laid down in AIS: 137 and as amended from time to time.
(xvi) The engine or vehicle fitted with engines shall be affixed with a
conformance label meeting the requirements as specified in AIS: 137
and as amended from time to time.
(xvii) For the vehicles specified under this rule, the emission sampled within
the control area as per procedure laid down in AIS-137 and as
