21. 12. 94 Official Journal of the European Communities No L 330/43 COMMISSION REGULATION (EC) No 3127/94 of 20 December 1994 amending Regulation (EC) No 2967/85 laying down detailed rules for the application of the Community scale for grading pig carcases THE COMMISSION OF THE EUROPEAN COMMUNITIES, Having regard to the Treaty establishing the European Community, Having regard to Council Regulation (EEC) No 3220/84 of 13 November 1984 determining the Community scale for grading pig carcases ('), as last amended by Regulation (EC) No 3513/93 (3, and in particular Article 5 (1) thereof, Whereas Regulation (EEC) No 3220/84 introduced the use of partial dissection of pig carcases as a means to obtain the total weight of the red striated muscles; whereas it is necessary to lay down in Commission Regu- lation (EEC) No 2967/85 (%), the details of the new assess- ment method in particular the number of carcases to be dissected and the new dissection method ; whereas the use of partial dissection leads to a new specification of the maximum tolerance for statistical error in assessment ; Whereas it is appropriate to improve the procedure for authorization of new grading methods by introducing a two-step protocol and by enumerating the different elements which it should contain ; Whereas the measures provided for in this Regulation are in accordance with the opinion of the Management Committee for Pigmeat, HAS ADOPTED THIS REGULATION : Article 1 Regulation (EEC) No 2967/85 is hereby amended as follows : 1. Article 3 is replaced by the following: Article 3 1. The method for assessing the lean meat content of carcases authorized as a grading method within the meaning of Article 2 (3) of Regulation (EEC) No () OJ No L 301, 20. 11. 1984, p. 1. () OJ No L 320, 22. 12. 1993, p. . () OJ No L 285, 25. 10. 1985, p. 39. 3220/84 is based on a representative sample of the national or regional pigmeat production concerned by the assessment method, consisting of at least 50 carcases whose lean meat content has been ascertained in accordance with the dissection method laid down in Annex I, combined with a nationally established quick method of carcase assessment using double regression or other statistically proven procedure, and such that the resulting precision is at least equal to that obtained using standard regression techniques on 120 carcases using the method in Annex L 2.  Authorization of the grading methods shall, moreover, be subjected to the root mean square devia- tion of the errors, measured about zero, being less than 2,5. 3. Member States shall inform the Commission, by way of a protocol, of the grading methods they wish to have authorized for application in their territory, describing the dissection trial and indicating the prin- ciples on which these methods are based and the equa- tions used for assessing the percentage of lean meat. The protocol should have two parts and should include the elements provided for in Annex I Part one of the protocol is presented to the Commission prior to the start of the dissection trial. Application of grading methods in the territory of a Member State shall be authorized in accordance with the procedure provided for in Article 24 of Regulation (EEC) No 2759/75 on the basis of the protocol. 4.  The application of grading methods must corres- pond in all particulars to the description given in the Community Decision authorizing them.; 2. The Annex to the present Regulation is added as Annex I and II to Regulation (EEC) No 2967/85. Article 2 This Regulation shall enter into force on 1 January 1995.
