Article 1U.K.Subject matter and scope

This Decision provides rules for the analytical methods to be used in the testing of official samples taken pursuant to [F1relevant [F2assimilated] law] and specifies common criteria for the interpretation of analytical results of official control laboratories for such samples.

This Decision shall not apply to substances for which more specific rules have been laid down in other F3... legislation.

Article 2U.K.Definitions

For the purpose of this Decision the definitions in Directive 96/23/EC and in the [F4Annex I] to this decision shall apply.

[F5In this Decision—

Article 3U.K.Analytical methods

The [F7appropriate authority] shall ensure that official samples taken pursuant to [F8relevant [F9assimilated] law] are analysed using methods that:

(a)are documented in test instructions, preferably according to ISO 78-2 (6);

(b)comply with Part 2 of the [F10Annex I] to this Decision;

(c)have been validated according to the procedures described in Part 3 of the [F10Annex I];

(d)comply with the relevant minimum required performance limits (MRPL) to be established in accordance with Article 4.

[F11Article 4U.K.Minimum required performance limits

[F12The appropriate authority] shall ensure that the analytical methods used for detecting the following substances meet the minimum required performance limits (MRPLs) set out in Annex II, against the matrixes referred to in that Annex:

(a)chloramphenicol;

(b)nitrofuran metabolites;

(c)medroxyprogesterone.

(d)malachite green.]

Article 5U.K.Quality control

The [F13appropriate authority] shall ensure the quality of the results of the analysis of samples taken pursuant to [F14relevant [F15assimilated] law], in particular by monitoring tests and/or calibration results according to Chapter 5.9 of ISO 17025 (1).

Article 6U.K.Interpretation of results

1.The result of an analysis shall be considered non-compliant if the decision limit of the confirmatory method for the analyte is exceeded.

2.If a permitted limit has been established for a substance, the decision limit is the concentration above which it can be decided with a statistical certainty of 1 - ɑ that the permitted limit has been truly exceeded.

3.If no permitted limit has been established for a substance, the decision limit is the lowest concentration level at which a method can discriminate with a statistical certainty of 1 - ɑ that the particular analyte is present.

4.For substances listed in Group A of Annex I to Directive 96/23/EC, the ɑ error shall be 1 % or lower. For all other substances, the ɑ error shall be 5 % or lower.
