that such reagents are available on a geo- graphically balanced basis. Member States should be able to take appropriate steps to encourage the use of such reagents.

    (5)           It is appropriate to introduce requirements that will enable the Member States to monitor and ensure, at the time of the periodic technical inspection, that heavy-duty vehicles equipped with exhaust after-treatment systems requiring the use of a consumable reagent have been properly oper- ated during the period preceding the inspection.

    (6)           Member States should be able to prohibit the use of any heavy-duty vehicle equipped with an exhaust after- treatment system that requires the use of a consumable reagent in order to achieve the emission limits for which such vehicles were granted a type-approval if the exhaust after-treatment system does not actually consume the required reagent or if the vehicle does not carry the required reagent.

    (7)           Manufacturers of heavy-duty vehicles equipped with exhaust after-treatment systems requiring the use of a con- sumable reagent should inform their customers how such vehicles should properly be operated.

    (8)           The requirements of Directive 2005/55/EC relating to the use of defeat strategies should be adapted to take account of technical progress. Requirements for multi-setting engines and for devices that can limit engine torque under certain operating conditions should also be specified.

    (9)           Annexes III and IV to Directive 98/70/EC of the European Parliament and of the Council of 13 October 1998 relat- ing to the quality of petrol and diesel fuel and amending Council Directive 93/12/EEC (1) require petrol and diesel motor fuels for sale throughout the Community to have a maximum sulphur content of 50 mg/kg (parts per million, ppm), from 1 January 2005. Motor fuels with a sulphur content of 10 mg/kg or less are increasingly available throughout the Community and Directive 98/70/EC requires such fuels to be available from 1 January 2009. The reference fuels used for the type-approval testing of engines against the emission limits specified in row B1, row B2 and row C of the tables in Annex I to Directive 2005/55/EC should therefore be redefined in order to bet- ter reflect, where applicable, the sulphur content of the die- sel fuels that are available on the market from 1 January 2005 and that are used by engines with advanced emission control systems. It is also appropriate to redefine the liq- uefied petroleum gas (LPG) reference fuel to reflect progress in the market since 1 January 2005.

    (10)        Technical adaptations to the sampling and measurement procedures are necessary to enable the reliable and repeat- able measurement of particulate mass emissions for compression-ignition engines that are granted a type- approval according to the particulate limits specified either in row B1, row B2
