Article 3

For the purpose of this Directive, ‘milk’ means the milk of cows, ewes, goats and buffaloes. The monthly surveys provided for in Article 4 (1) (a) shall cover only cow's milk and products manufactured exclusively from cow's milk.

The Commission shall be empowered to adopt delegated acts, in accordance with Article 6a, to amend, the list of milk products covered by the surveys and to lay down the standard definitions applicable for the communication of the results for the various products.

Those delegated acts shall be adopted only where they are necessary in order to take account of economic and technical developments; they do not change the optional nature of the required information and they do not impose a significant additional burden on Member States or on the respondents.

The Commission shall duly justify the statistical actions provided for in those delegated acts, using, where appropriate, input from relevant experts based on a cost-effectiveness analysis, including an assessment of the burden on the respondents and of the production costs, as referred to in point (c) of Article 14(3) of Regulation (EC) No 223/2009 of the European Parliament and of the Council ^f1 .
