Article 7
1. In order to ascertain the weight of the quantities put up for sale and landed the recipient units, or the transport vehicle into which these quantities are loaded, shall be weighed. If such weighing cannot be carried out, the weight of the landed quantities shall be calculated by addition of the contents of the standardized boxes in which the quantities must be landed. However, a supplementary weighing by sample shall be carried out for the standardized boxes. 2. If the quantities are presented for public auction in standardized boxes to be marketed for a particular sale, weighing shall be carried out according to the provisions of Article 5. 3. The weight of quantities transshipped on board a vessel shall be calculated by applying the coefficients shown in Annex I: - on the one hand, to the volume of the catches taken by each vessel or to the contents of each tank as measured by the appropriate technical means, - on the other hand, to the volume of the quantities transshipped to the processing vessel as measured by means of the recipient approved by the office responsible for weights and measures in the Member State concerned.
