75 <= kW < 130 1.4.2011 5.0 4.0 0.3
130 <= kW < 560 1.4.2011 3.5 4.0 0.2
Notes :—
1. The test shall be on Engine Dynamometer.
2. The test procedure for measurement of Gross Power (without Fan) shall be
as per Part IV of MoSRTH/CMVR/TAP-115/116 Issue No. 3.
3. The test procedure for measurement of emission of visible and gaseous
pollutants and Particulate Matter shall be as per MoSRTH/CMVR/
TAP-115/116 Part X (Sub-part A).
4. Test fuel shall be the reference fuel as specified in Annexure IV P.
5. The emission of visible pollutants, when tested as provided in sub-rule (3)
of rule 115A, shall not exceed the limit values given therein.
6. To meet Bharat (Trem) Stage-III A norms with effect from the date specified
in Column (2) of Table 1, the engine manufacturer may opt for an ageing
test as specified in Table 2 for evaluating deterioration factors as per
Annexure V of Part X (Sub-part-B) of MoSRTH/CMVR/TAP-115-116 Issue
No. 3 or fixed deterioration factors as per Table 3.

7. There shall be no relaxation of norms for Conformity of Production (COP)
purposes.
8. Conformity of Production (COP) Selection Procedure shall be as per
MoSRTH/CMVR/TAP-115/116 Part VI.
9. Conformity of Production (COP) Frequency shall be as per Part X (Sub-part
A) of MoSRTH/CMVR/TAP-115/116.
10. The extension of Type Approval (TA) to engine family and engine
after-treatment system family shall be specified in
MoSRTH/CMVR/TAP-115/116 as amended from time to time.
Explanation 1: The term “engine family” includes a range of engines having
similar design parameters for emission levels.
Explanation 2 : The term “engine after-treatment system family” means if
same after-treatment system consisting of catalyst, particulate traps etc., is
used on a series of engines, then the deterioration factor based on one engine
test shall be applicable to the entire series.]
