No L 51/50 Official Journal of the European Communities 20. 2. 87 COMMISSION DECISION of 26 January 1987 authorizing a method for grading pig carcases in the Netherlands (Only the Dutch text is authentic) (87/131/EEC) THE COMMISSION OF THE EUROPEAN COMMUNITIES, Having regard to the Treaty establishing the European Economic Community, Having regard to Council Regulation (EEC) No 2759/75 of 29 October 1975 on the common organization of the market in pigmeat ('), as last amended by Regulation (EEC) No 1475/86 (%), and in particular Article 4 (6) thereof, Having regard to Council Regulation (EEC) No 3220/84 - of 13 November 1984 determining the Community scale for grading pig carcases (), as amended by Regulation (EEC) No 3530/86 (%), and in particular Article 5 (2) thereof, Whereas Article 2 (3) of Regulation (EEC) No 3220/84 provides that the grading of pig carcases must be deter- mined by estimating the content of lean meat in accor- dance with statistically proven assessment methods based on the physical measurement of one or more anatomical parts of the pig carcase; whereas the authorization of grading methods is subject to compliance with a maximum tolerance for statistical error in assessment ; whereas this tolerance has been defined in Article 3 of Commission Regulation (EEC) No 2967/85 of 24 October 1985 laying down detailed rules for the application of the Community scale for grading pig carcases () ; \ Whereas the Government of the Netherlands has requested the Commission to authorize a method for grading pig carcases and has submitted the details required in Article 3 of Regulation (EEC) No 2967/85; whereas an examination of this request has revealed that the conditions for authorizing the said grading method are fulfilled; Whereas no modification of the apparatus or grading method may be authorized except by means of a new Commission Decision adopted in the light of experience gained ; ) OJ No L 282, 1. 11. 1975, p. 1. %) O] No L 133, 21. 5. 1986, p. 39.

Whereas the measures provided for in this Decision are in accordance with the opinion of the Management Committee for Pigmeat, HAS ADOPTED THIS DECISION : Article 1 1. Use of the apparatus termed ‘Hennessy Grading Probe (HGP 2) is hereby authorized as the sole method for grading pig carcases in the Netherlands. 2. The apparatus shall be equipped with a probe of 5,95 millimetres in diameter (and of 6,3 millimetres at the blade on top of the probe) containing a photodiode (LED Siemens of the type LYU 260-EO and photodetector of the type 58 MR) and having an operating distance of between 0 and 120 millimetres. The results of the measu- rements shall be converted into estimated lean meat content by means of the HGP 2 itself as well as a computer linked to it. 3. The lean meat content of the carcase shall be calcu- lated according to the following formula: 9 = 6133 — 076x, + 0,10x, where : ¥ = the estimated percentage of lean meat in the carcase, x; = the thickness of backfat (including rind) in milli- metres, measured at 6 centimetres off the midline of the split carcase, between the third and fourth last ribs, x, = the thickness of muscle in millimetres, measured at the same time and in the same place as x,. This formula shall be valid for carcases weighing between 50 and 120 kg. Article 2 Modification of the apparatus or of the assessment method shall not be authorized.
