Denmark, Ireland and the United Kingdom joined the EEC in 1973. The directive had little impact in Denmark which was in a similar situation to the other EEC member vis-à-vis the use of metric units. Ireland and the United Kingdom were in the process of metrication programmes and the directive was consistent with those countries policies as they stood at the time. The three new member states had five years to implement this directive (as well as all other directives that had been published by the EEC).
