COUNCIL DIRECTIVE of 16 December 1980 on the approximation of the laws of the Member States relating to the fuel consumption of motor vehicles (80/1268/EEC)

Id-Direttiva tal-Kunsill

THE COUNCIL OF THE EUROPEAN COMMUNITIES,

tas-16 ta’ Diċembru 1980

Having regard to the Treaty establishing the European Economic Community, and in particular Article 100 thereof,

dwar l-approssimazzjoni tal-liġijiet tal-Istati Membri dwar il-konsum tal-karburanti mill-vetturi bil-magna

Having regard to the proposal from the Commission (1),

(80/1268/KEE)

Having regard to the opinion of the European Parliament (2),

IL-KUNSILL TAL-KOMUNITAJIET EWROPEJ,

Having regard to the opinion of the Economic and Social Committee (3),

Wara li kkunsidra t-Trattat li jistabbilixxi l-Komunità Ekonomika Ewropea, u partikolarment l-Artikolu 100 tiegħu,

Whereas the technical requirements which motor vehicles must satisfy pursuant to certain national laws relate inter alia to the method of measuring fuel consumption which must be used to indicate the fuel consumption of a vehicle type;

Wara li kkunsidra l-proposta mill-Kummissjoni [1],

Whereas those requirements differ from one Member State to another ; whereas this results in technical barriers to trade which must be eliminated by all Member States adopting the same requirements either in addition to or in place of their existing rules, in order in particular to allow the EEC type-approval procedure which was the subject of Council Directive 70/156/EEC of 6 February 1970 on the approximation of the laws of the Member States relating to the type-approval of motor vehicles and their trailers (4), as last amended by Directive 80/1267/EEC (5), to be introduced in respect of each type of vehicle;

Wara li kkunsidra l-opinjoni tal-Parlament Ewropew [2],

Whereas it is of paramount importance to establish a method of measuring fuel consumption by motor vehicles for inclusion in Community requirements;

Wara li kkunsidra l-opinjoni tal-Kumitat Ekonomiku u Soċjali [3],

Whereas a Community method of measuring fuel consumption is also necessary to ensure, in particular, that customers and users are supplied with objective and precise information;

Billi l-ħtiġiet tekniċi li l-vetturi bil-magna għandhom jissodisfaw permezz ta’ ċerti liġijiet nazzjonali li jirrelataw inter alia għall-metodu tal-kejl tal-konsum tal-karburanti li għandu jintuża biex jindika l-konsum tal-karburanti tat-tip ta’ vettura;

Whereas the requirements of this Directive apply only to motor vehicles in international motor vehicle classification category M1 as set out in Directive 70/156/EEC ; whereas a method of measuring the fuel consumption of the other categories of motor vehicles will be established as soon as certain technical difficulties can be resolved,

Billi dawk il-ħtiġiet jiddifferixxu minn Stat Membru għall-ieħor; billi dan jirriżulta f’ barrieri tekniċi għall-kummerċ li għandhom jiġu eliminati mill-Istati Membri kollha billi jadottaw l-istess ħtiġiet jew flimkien ma’, jew minflok ir-regoli eżistenti tagħhom, partikolarment sabiex jippermettu li tiġi introdotta għal kull tip ta’ vettura l-proċedura ta’ l-approvazzjoni tat-tip KEE li kienet is-suġġett tad-Direttiva tal-Kunsill70/156/KEE tas-6 ta’ Frar 1970 dwar l-approssimazzjoni tal-liġijiet tal-Istati Membri dwar l-approvazzjoni tat-tip ta’ vetturi bil-magna u l-karrijiet tagħhom [4], kif l-aħħar emendata bid-Direttiva 80/1267/KEE [5];

HAS ADOPTED THIS DIRECTIVE:

Billi huwa ta’ importanza massima li jkun stabbilit il-metodu għall-kejl tal-konsum tal-karburanti mill-vetturi bil-magna għall-inklużjoni fil-ħtiġiet tal-Komunita;

Billi metodu tal-Komunita għall-kejl tal-konsum tal-karburanti huwa wkoll meħtieġ biex ikun assigurat, partikolarment, li l-klijenti u l-utenti jkunu pprovduti b’informazzjoni oġġettiva u preċiża;

Article 1

Billi l-ħtiġiet ta’ din id-Direttiva japplikaw biss għall-vetturi bil-magna fil-klassifikazzjoni tal-vetturi bil-magna internazzjonali M1 kif stabbilit bid-Direttiva 70/156/KEE; billi metodu tal-kejl tal-konsum tal-karburanti tal-kategoriji l-oħrajn ta’ vetturi bil-magna jiġi stabbilit malli jkunu riżolti ċerti diffikultajiet tekniċi,

For the purpose of this Directive, "vehicle" means any motor vehicle intended for use on the road, with or without bodywork, having at least four wheels and a maximum design speed exceeeding 25 km/h, with the exception of vehicles which run on rails and of agricultural tractors and machinery.

ADOTTA DIN ID-DIRETTIVA:

6.3.1.5. To determine the consumption at each reference speed (see graph below), four tests are performed ; two at an average speed less than the reference speed and two at an average speed exceeding the reference speed.

6.1.1. Il-massa tal-vettura

6.3.1.6. The fuel consumption for each test run is calculated from the formulae in 5.4.

L-għoli tas-sospensjoni tal-vettura hija dik akkwistata meta ċ-ċentru tal-gravità tat-tgħabija huwa fin-nofs ta’ linja dritta li tgħaqqad il-punti R tas-sedili ta’ quddiem (ġenb).

6.3.1.7. The difference between the two lower calculated values must not exceed 5 % of their average value, this same condition applying also to the two higher calculated values. The value of the fuel consumption at the appropriate reference speed is calculated by linear interpolation as shown on the graph below. 6.3.1.7.1. If the conditions in 6.3.1.7 are not achieved for either pair of calculated values, the four test runs must be repeated. If after ten attempts the required consistency has not been achieved, another vehicle must be selected and subjected to all the tests specified in this procedure.
