Translation of "reference method " (English → French) :

(4) Measurements shall be taken of the amount of mercury released into the ambient air per day from sources specified in subsection (1) by taking the arithmetical average of not less than three measurements conducted for each source in the same day in accordance with the appropriate method, or any other method the results of which can be confirmed by the appropriate method, described in Standard Reference Methods for Source Testing: Measurement of Emissions of Mercury from Mercury Cell Chlor-Alkali Plants, Department of the Environment Report EPS 1-AP-76-1 dated November 1976, as amended from time to time.

The reference method for the sampling and measurement of PM is that described in EN 12341:1999 ‘Air Quality — Determination of the PM fraction of suspended particulate matter — Reference method and field test procedure to demonstrate reference equivalence of measurement methods’.

that the national laboratories, when appointed by the appropriate competent authority or body designated pursuant to Article 3, that are taking part in Community-wide intercomparisons covering pollutants regulated in this Directive, are accredited according to EN/ISO 17025 by 2010 for the reference methods referred to in Annex VI. These laboratories shall be involved in the coordination on Member States territory of the Community wide quality assurance programmes to be organised by the Commission and shall also coordinate, on the national level, the appropriate realisation of reference methods and the demonstration of equivalence of non ...[+++]-reference methods.

1. A Member State may use any other method which it can demonstrate gives results equivalent to any of the methods referred to in Section A or, in the case of particulate matter, any other method which the Member State concerned can demonstrate displays a consistent relationship to the reference method.

Consequently, ISO 16649-3 should be specified as the reference MPN (most probable number) method for analysis of E. coli in bivalve molluscs originating in areas B and C too. The use of alternative methods should be allowed only where they are considered equivalent to the reference method.

III. In applying this Agreement, the Parties agree that the methods of analysis recognised as reference methods by the International Vine and Wine Office (OIV) and published by that Office or, where an appropriate method does not appear in this publication, a method of analysis complying with the standards recommended by the International Organisation for Standardisation (ISO), shall prevail as reference methods for the determination of the analytical composition of the wine in the context of control operations.
