Article 1 

1. For grading pig carcases presented in accordance with the first paragraph of point B.III of Annex V to Regulation (EC) No 1234/2007 the use of the following method is authorised in Greece, pursuant to paragraph 1 of point B.IV of that Annex: the ‘OptiScan-TP’ apparatus and the assessment methods related thereto, details of which are given in Part I of the Annex to this Decision.
2. For grading dehided pig carcases the use of the following methods is authorised in Greece pursuant to paragraph 1 of point B.IV of Annex V to Regulation (EC) No 1234/2007:
(a) the ‘OptiScan-TP’ apparatus and the assessment methods related thereto, details of which are given in Part I of the Annex to this Decision;
(b) the ‘Hennessy Grading Probe (HGP 4)’ apparatus and the assessment method related thereto, details of which are given in Part II of the Annex to this Decision.
Article 2 
Notwithstanding the standard presentation laid down in the first paragraph of point B.III of Annex V to Regulation (EC) No 1234/2007, pig carcases in Greece may be dehided in a uniform manner before being weighed and graded. In order to establish quotations for pig carcases on a comparable basis, the recorded hot carcase weight shall be adjusted according to the following formula:
hot carcase weight = 1,05232 × weight of the dehided carcase
Article 3 
Modifications of the apparatus or the assessment method shall not be authorised.
Article 4 
This Decision is addressed to the Hellenic Republic.
ANNEX
Part I  1. The rules provided for in this Part shall apply when the grading of pig carcases is carried out by means of the apparatus known as ‘OptiScan-TP’.
 2. 
The results of the measurements shall be converted into estimated lean meat content by means of the Optiscan-TP apparatus itself. The photos shall be saved and can later be controlled. The integrated Bluetooth® interface permits easy data transfer.

3a. Formula for grading pig carcases presented in accordance with the first sentence of point B.III of Annex V to Regulation (EC) No 1234/2007:
Ŷ = 62,94974 – 0,79348 × X1 + 0,13218 × Χ2
where:
Ŷthe estimated percentage of lean meat in the carcase,Χ1the minimal thickness of fat (including rind) in millimetres, over the M. gluteus medius,Χ2the thickness of the lumbar muscle in millimetres, measured as the shortest distance from the front (cranial) end of the M. gluteus medius to the upper (dorsal) edge of the spinal canal.
3b. Formula for grading dehided pig carcases:
Ŷ = 60,91227 – 0,80881 × X1s + 0,13710 × Χ2
where:
Ŷthe estimated percentage of lean meat in the carcase,Χ1sthe minimal thickness of fat (without rind) in millimetres, over the M. gluteus medius,Χ2the thickness of the lumbar muscle in millimetres, measured as the shortest distance from the front (cranial) end of the M. gluteus medius to the upper (dorsal) edge of the spinal canal.
These formulas shall be valid for carcases weighing between 50 and 110 kilograms.

Part II  1. The rules provided for in this Part shall apply when the grading of pig carcases is carried out by means of the apparatus known as ‘Hennessy Grading Probe (HGP 4)’.
 2. The apparatus shall be equipped with a probe of 5,95 millimetres diameter (and of 6,3 millimetres at the blade on top of the probe) containing a photodiode (Siemens LED of the type LYU 260-EO) and photodetector of the type Silonex SLCD-61N1 and having an operating distance of between 0 and 120 millimetres. The results of the measurements shall be converted into estimated lean meat content by means of the HGP 4 itself or a computer linked to it.
 3. Ŷ = 62,400 – 0,495 × X1 – 0,559 × Χ2 + 0,129 × Χ3
where:

Ŷthe estimated percentage of lean meat in the carcase,Χ1the thickness of back-fat (without rind) in millimetres, measured at 8 centimetres off the midline of the carcase at the level of the last rib,Χ2the thickness of back-fat (without rind) in millimetres, measured at 6 centimetres off the midline of the carcase between the third and fourth last ribs,Χ3the thickness of the dorsal muscle in millimetres, measured at the same time and in the same place as X2.

This formula shall be valid for carcases weighing between 60 and 120 kilograms.
