Council Directive 1999/30/EC (repealed)Show full title

ANNEX IX U.K. REFERENCE METHODS FOR ASSESSMENT OF CONCENTRATIONS OF SULPHUR DIOXIDE, NITROGEN DIOXIDE AND OXIDES OF NITROGEN, PARTICULATE MATTER (PM₁₀ AND PM_2,5) AND LEAD

I. Reference method for the analysis of sulphur dioxide: U.K.

ISO/FDIS 10498 (Standard in draft) Ambient air — determination of sulphur dioxide — ultraviolet fluorescence method.

A Member State may use any other method which it can demonstrate gives results equivalent to the above method.

II. Reference method for the analysis of nitrogen dioxide and oxides of nitrogen: U.K.

ISO 7996: 1985 Ambient air — determination of the mass concentrations of nitrogen oxides — chemiluminescence method.

A Member State may use any other method which it can demonstrate gives results equivalent to the above method.

III.A Reference method for the sampling of lead: U.K.

The reference method for the sampling of lead will be that described in the Annex to Directive 82/884/EEC until such time as the limit value in Annex IV to this Directive is to be met, when the reference method will be that for PM₁₀ as laid down in Section IV of this Annex.

A Member State may use any other method which it can demonstrate gives results equivalent to the above method.

III.B Reference method for the analysis of lead: U.K.

ISO 9855: 1993 Ambient air — Determination of the particulate lead content of aerosols collected in filters. Atomic absorption spectroscopy method.

A Member State may use any other method which it can demonstrate gives results equivalent to the above method.

IV. Reference method for the sampling and measurement of PM₁₀ U.K.

The reference method for the sampling and measurement of PM₁₀ will be that described in EN 12341 ‘Air Quality — Field Test Procedure to Demonstrate Reference Equivalence of Sampling Methods for the PM₁₀ fraction of particulate matter’. The measurement principle is based on the collection on a filter of the PM₁₀ fraction of ambient particulate matter and the gravimetric mass determination.

A Member State may use any other method which it can demonstrate gives results equivalent to the above method or any other method which the Member State concerned can demonstrate displays a consistent relationship to the reference method. In that event the results achieved by that method must be corrected by a relevant factor to produce results equivalent to those that would have been achieved by using the reference method.

Each Member State must inform the Commission of the method used to sample and measure PM₁₀. The Commission must as soon as possible carry out intercomparison exercises for PM₁₀ sampling and measurement methods in order to provide information for the review of this Directive in accordance with Article 10.

V. Provisional reference method for the sampling and measurement of PM_2,5 U.K.

The Commission will produce guidelines, in consultation with the committee referred to in Article 12 of Directive 96/62/EEC, for an appropriate provisional reference method for the sampling and assessment of PM_2,5 by 19 July 2001.

A Member State may use any other method which it considers suitable.

Each Member State must inform the Commission of the method used to sample and measure PM_2,5. The Commission must as soon as possible carry out intercomparison exercises for PM_2,5 sampling and measurement methods in order to provide information for the review of this Directive in accordance with Article 10.
