Article 25 3.

As regards the conduct of measurements and tests, the technical requirements shall be met in respect of:

(a) 

apparatus and procedures for the conduct of tests;

(b) 

apparatus and procedures for emission measurement and sampling;

(c) 

methods for data evaluation and calculations;

(d) 

methods for establishing deterioration factors;

(e) 

in relation to engines in categories NRE, NRG, IWP, IWA, RLR, NRS, NRSh, SMB and ATS complying with Stage V emission limits set out in Annex II:

(i) 

methods for taking account of emissions of crankcase gases;

(ii) 

methods for determining and taking account of continuous or infrequent regeneration of exhaust after-treatment systems;

(f) 

in relation to electronically controlled engines in categories NRE, NRG, IWP, IWA, RLL and RLR complying with Stage V emission limits set out in Annex II and using electronic control to determine both the quantity and timing of injecting fuel or using electronic control to activate, de-activate or modulate the emission control system used to reduce NOx:

(i) 

emission control strategies, and shall include the documentation required to demonstrate those strategies;

(ii) 

NOx control measures, and shall include the method used to demonstrate those control measures;

(iii) 

the area associated with the relevant non-road steady-state test cycle, within which the amount by which the emissions are permitted to exceed the emission limits set out in Annex II is controlled;

(iv) 

the selection by the technical service of additional measurement points from within the control area during the emission bench test.
