Division 4 Test requirements

F1The test shall be carried out immediately after the applicable NRSC as follows:

1. (a)

   the test of the randomly selected torque and speed points shall either be carried out immediately after the discrete-mode NRSC test sequence described in points (a) to (e) of point 7.8.1.2 of Annex VI but before the post test procedures (f) or after the ramped modal non-road steady- state test cycle ( ‘ RMC ’ ) test sequence described in points (a) to (d) of point 7.8.2.3 of Annex VI but before the post test procedures (e) as relevant;

2. (b)

   the tests shall be carried out as required in points (b) to (e) of point 7.8.1.2 of Annex VI using the multiple filter method (one filter for each test point) for each of the test points chosen in accordance with section 3;

3. (c)

   a specific emission value shall be calculated (in g/kWh or #/kWh as applicable) for each test point;

4. (d)

   emissions values may be calculated on a mass basis using section 2 of Annex VII or on a molar basis using section 3 of Annex VII, but shall be consistent with the method used for the discrete-mode NRSC or RMC test;

5. (e)

   for gaseous and PN, if applicable, summation calculations, N _mode in equations (7-64) or (7-131) and (7-178) shall be set to 1 and a weighting factor of 1 shall be used;

6. (f)

   for PM calculations the multiple filter method shall be used; for summation calculations, N _mode in equations (7-67) or (7-134) shall be set to 1 and a weighting factor of 1 shall be used.
