Division 4.3.1.2
United Kingdom
The emissions control system shall be aged according to the procedure described in point 4.3.2.4 and retested to establish the durability of its emissions performance.
The durability of a replacement pollution control device is determined from a comparison of the two successive sets of exhaust gas emissions tests:
- (a)
the first set is that made with the replacement pollution control device which has been run in with 12 WHSC Cycles;
- (b)
the second set is that made with the replacement pollution control device which has been aged by the procedures detailed below.
Where approval is applied for different types of engines from the same engine manufacturer, and provided that these different types of engines are fitted with an identical original equipment pollution control system, the testing may be limited to at least two engines selected after agreement with the approval authority.
