COUNCIL DIRECTIVE
of 21 December 1989
amending Directive  87/402/EEC on roll-over protection structures mounted in front of the driver's seat on narrow-track  wheeled agricultural and forestry tractors
(89/681/EEC)
THE COUNCIL OF THE EUROPEAN  COMMUNITIES
,
Having regard to the Treaty establishing the European Economic Community, and in particular Article  100a thereof,
Having regard to the proposal from the Commission (1),
In cooperation with the European Parliament (2),
Having regard to the opinion of the Economic and Social Committee (3),
Whereas it is necessary to adopt measures with the aim of progressively establishing the internal  market over a period expiring on 31 December 1992; whereas the internal market comprises an area  without internal frontiers in which the
free movement of goods, persons, services and capital is  ensured;
Whereas Article 12 of Directive 87/402/EEC (4) lays down that the said Directive shall be  supplemented by provisions introducing additional impact tests into the dynamic test procedure;
Whereas, since provision is already made for an additional test in the case of the static test  procedure, it is necessary also in that of the dynamic test procedure to provide for an additional  test - which more accurately reflects the situation in the event of tractor roll-over - in order  that these two test procedures may be rendered equivalent and the present imbalance between them  eliminated;
Whereas, in respect of the reliability of the parameters and calculations, the results of the  practical experiments carried out on rear-mounted structures may be transposed to the same type of  structure, but mounted on the front,
