Commission Regulation (EEC) No 1858/88 of 30 June 1988 amending Regulation (EEC) No 1058/77 on the characteristics of olive oil and of certain products containing olive oil and amending the Common Customs Tariff Nomenclature as regards olive oil
Regulation (EEC) No 1058/77 is hereby amended as follows:
1. The title is replaced by the following: 'Commission Regulation (EEC) No 1058/77 of 18 May 1977 concerning the characteristics of olive oil and certain products containing olive oil'.
2. The following paragraph 3 is added to Article 2:
'3. The tetrachloroethylene content of olive oil and of olive-pomace oil shall be determined by the method set out in Annex X. However, until 31 October 1989 Member States may decide that the tetrachloroethylene content can be determined by other methods giving results which are compatible with the standard method. The Member States concerned shall communicate to the Commission those other methods before using them. If the tetrachloroethylene content determined by another method differs from that determined by the standard Community method, the content determined by the standard method shall apply.'
3. The following line is added in the Table of Annexes:
'Annex X Tetrachloroethylene content 26'
4. In paragraph 1 of Annex I and in paragraph B.I of Annex III the following point (g) is added:
'(g) a tetrachloroethylene content measured by the method set out in Annex X no greater than 0,1 mg/kg.'
5. The following indent is added in paragraph 2 of Annex I and in paragraph B.II of Annex III:
'- those indicated at (a), (b), (c), (d), (e) and (f) in paragraph 1 and a tetrachloroethylene content measured by the method set out in Annex X greater than 0,1 mg/kg.'
6. Annex X annexed hereto is added.
Regulation (EEC) No 2658/87 is hereby adapted as a consequence of Article 1 (4) and (5).
This Regulation shall enter into force on 1 July 1988.
However, Article 1 (4) and (5) shall apply from 1 November 1988 for buying into intervention pursuant to Commission Regulation (EEC) No 3472/85 (1).
This Regulation shall be binding in its entirety and directly applicable in all Member States.

DETERMINATION OF TETRACHLOROETHYLENE CONTENT OF OLIVE OIL
Method
Analysis by gas chromatography using the head space technique.
Equipment
1. Gas chromatography apparatus fitted with an electron capture detector (ECD).
2. Head space.
3. Gas chromatography column, of glass, 2 metres long and 2 mm in diameter, stationary phase.
OV101 10 % or equivalent, impregnating a calcined diatomaceous earth, acid washed and silamized and of a particle size of 80 to 100 mesh.
4. Carrier and auxiliary gas: nitrogen for gas chromatography, suitable for detection by electron capture.
5. Glass flasks, 10 to 15 ml, with teflon coating and aluminium stopper with fitment for entry of syringe.
6. Hermetically sealing clamps.
7. Gas syringe 0,5 to 2 ml.
Reagents
Standard: - tetrachloroethylene of a degree of purity suitable for gas chromatography,
- pentane of a degree of purity suitable for gas chromatography.
Procedure
1. Exactly weigh around 3 g of oil in a glass flask (not to be reused), hermetically seal it. Place it in a thermostat at 70 Β°C for one hour. Using a syringe carefully remove 0,2 to 0,5 ml of the head space. Inject this into the column of the gas chromatography apparatus regulated as follows:
- injector temperature 150 Β°C
- column temperature: 70 to 80 Β°C
detector temperature: 200 to 250 Β°C
Other temperatures may also be used provided the results remain equivalent.
2. Reference solutions. Prepare standard solutions using refined olive oil with no trace of solvents with tetrachloroethylene concentrations ranging from 0,05 to 1 mg/kg and corresponding to the presumed content of the sample. The tetrachloroethylene may be diluted using pentane.
3. Quantitative assessment. Correlate the surfaces or the elevations of the peaks of the sample and of the standard solution of the concentration presumed closest. If the deviation is greater than 10 % the analysis must be repeated in comparison with another standard solution until the deviation is within 10 %. The tetrachloroethylene content is determined on the basis of the average of the elementary injections.
4. Expression of results: in mg/kg (ppm). The detection limit for the method is 0,01 mg/kg.
