No L 238/40 Official Journal of the European Communities 21. 8. 87 COMMISSION DIRECTIVE of 29 July 1987 on crude-oil savings through the use of substitute fuel components in petrol (87/441/EEC) THE COMMISSION OF THE EUROPEAN COMMUNITIES, Having regard to the Treaty establishing the European Economic Community, Having regard to Council Directive 85/536/EEC of § December 1985 on crude-oil savings through the use of substitute fuel components in petrol ('), and in particular Article 4 thereof, Whereas it is necessary to cite reference methods for measuring substitute fuel components likely to be used in petrol blends ; Whereas scientific and technical progress has demon- strated that a number of measuring methods can be used on a provisional basis ; Whereas the measures provided for in this Directive are in accordance with the opinion of the Committee on the Adaptation to Scientific and Technical Progress of the abovementioned Directive, HAS ADOPTED THIS DIRECTIVE : Article 1 Section III of the Annex to Directive 85/536/EEC is hereby supplemented by the following text, the other provisions of this Section remaining unchanged : ‘The following methods may be used on a provisional basis for measuring the proportions by volume and proportions of oxygen content by weight of the organic oxygenate compounds in petrol blends. 1.
