Article 4
United Kingdom
The cryogenic media authorized, to the exclusion of all others, for use in direct contact with quick-frozen foodstuffs shall be the following:
-
air,
-
nitrogen,
-
carbon dioxide.
By way of derogation from the first paragraph, Member States may retain until 31 December 1992 national laws authorizing the use of dichlorodifluoromethane (R 12) as a cryogenic medium.
F1The purity criteria to be satisfied by those cryogenic media shall be determined, as far as necessary, by the Commission. Those measures, designed to amend non-essential elements of this Directive by supplementing it, shall be adopted in accordance with the regulatory procedure with scrutiny referred to in Article 12(2).
