Division 3.2.6.1
United Kingdom
As an alternative to using a service accumulation schedule to determine DFs, engine manufacturers may select to use assigned multiplicative DFs, as given in Table 3.1.
Table 3.1
Assigned deterioration factors
| Test cycle | CO | HC | NOx | PM | PN |
|---|---|---|---|---|---|
| NRTC and LSI-NRTC | 1,3 | 1,3 | 1,15 | 1,05 | 1,0 |
| NRSC | 1,3 | 1,3 | 1,15 | 1,05 | 1,0 |
Assigned additive DFs shall not be given. The assigned multiplicative DFs shall not be transformed into additive DFs.
