Having regard to the Treaty
Community,

establishing the European

Having regard to Directive 2005/55/EC of
the European
Parliament and of the Council of 28 September 2005 on the
approximation of the laws of the Member States relating to the
measures to be taken against the emission of gaseous and par­
ticulate pollutants from compression-ignition engines for use in
vehicles, and the emission of gaseous pollutants from positive-
ignition engines fuelled with natural gas or liquefied petroleum
gas for use in vehicles (1), and in particular Article 7 thereof,

(2)

Following the change of scope of Directive 2005/55/EC
the
introduced by Regulation (EC) No 715/2007 of
European Parliament and of
the Council of 20 June
2007 on type approval of motor vehicles with respect
to emissions
from light passenger and commercial
vehicles (Euro 5 and Euro 6) and on access to vehicle
repair and maintenance information (2), it is necessary to
further amend this Directive by transferring the relevant
technical requirements. Consequently, it is also necessary
to amend Commission Directive 2005/78/EC (3), which
implements that Directive.

As a consequence of the change of scope, it is necessary
to introduce new requirements
into the heavy-duty
emissions legislation set up by Directive 2005/55/EC.
These requirements include test procedures to enable
type approval of heavy-duty engines and vehicles with
petrol engines.

time, and/or dilution ratio, accordingly, so that the criterion for the effective weighting factors in Section
6.6 is met.

The sampling time per mode shall be at least four seconds per 0,01 weighting factor. Sampling shall be
