emissions measurement (M'sij) shall be reported in Annex 1, items 4.2.11.2.1.10.1. to 4.2.11.2.1.10.4. or 4.2.11.2.5.4.1. to 4.2.11.2.5.4.4. as applicable.
              3.2. Measurement of emissions during regeneration
              3.2.1. Preparation of the vehicle, if required, for the emissions test during a regeneration phase, may be completed using the preparation cycles in paragraph 6.3. of Annex 4a or equivalent engine test bench cycles, depending on the loading procedure chosen in paragraph 3.1.2. above.
              3.2.2. The test and vehicle conditions for the Type I test described in Annex 4a apply before the first valid emission test is carried out.
              3.2.3. Regeneration must not occur during the preparation of the vehicle. This may be ensured by one of the following methods:
              3.2.3.1. A "dummy" regenerating system or partial system may be fitted for the pre-conditioning cycles.
              3.2.3.2. Any other method agreed between the manufacturer and the type approval authority.
              3.2.4. A cold-start exhaust emission test including a regeneration process shall be performed according to the Type I operating cycle, or equivalent engine test bench cycle. If the emissions tests between two cycles where regeneration phases occur are carried out on an engine test bench, the emissions test including a regeneration phase shall also be carried out on an engine test bench.
              3.2.5. If the regeneration process requires more than one operating cycle, subsequent test cycle(s) shall be driven immediately, without switching the engine off, until complete regeneration has been achieved (each cycle shall be completed). The time necessary to set up a new test should be as short as possible (e.g. particular matter filter change). The engine must be switched off during this period.
              3.2.6. The emission values during regeneration (Mri) shall be calculated according to Annex 4a, paragraph 6.6. The number of operating cycles (d) measured for complete regeneration shall be recorded.
              3.3. Calculation of the combined exhaust emissions of a single regenerative system

Where for each pollutant (i) considered:
 M'sij                                    =  mass emissions of pollutant (i) in g/km over one Type I operating cycle (or equivalent engine test bench cycle) without regeneration,
 M'rij                                    =  mass emissions of pollutant (i) in g/km over one Type I operating cycle (or equivalent engine test bench cycle) during regeneration (if d > 1, the first Type I test is run cold, and subsequent cycles are hot),
 Msi                                      =  mass emissions of pollutant (i) in g/km without regeneration,
 Mri                                      =  mass emissions of pollutant (i) in g/km during regeneration,
 Mpi                                      =  mass emissions of pollutant (i) in g/km,
 n                                        =  number of test points at which emissions measurements (Type I operating cycles or equivalent engine test bench cycles) are made between two cycles where regenerative phases occur,  2,
