1.14 General. In English, proper names are capitalised but ordinary nouns are not. The titles and names of persons, bodies, programmes, legal acts, documents, etc. are therefore normally capitalised
NB: in English unlike in some other languages, all the nouns and adjectives in names take capitals

1.15 However, for long names that read more like a description than a real title use lower case:
Committee for the adaptation to technical progress of the Directive on the introduction of recording equipment in road transport (tachograph)

The general rule is 'the longer the name, the fewer the capitals.'
