(2)  Consequently the provisions laid down in Directive 70/156/EEC relating to vehicle systems, components and separate technical wunits apply to Directive 72/306/EEC. (3)  Article 9(2) of Directive 70/156/EEC, as amended by Directive 92/53/EEC (°), provides for the equivalence between the separate Directives and the corresponding Regulations of the United Nations Economic Commission for Europe (UN-ECE).

It is also appropriate to align the fuel used for measuring the opacity of the exhaust with the fuel permitted for the measurement of emissions, as given in Council Directive 88/77[EEC (4).
