ANNEX VI

Reference methods for assessment of concentrations of sulphur dioxide, nitrogen dioxide and oxides of nitrogen, particulate matter (PM10 and PM2,5), lead, benzene, carbon monoxide, and ozone

▼M1

A.   Reference methods for the assessment of concentrations of sulphur dioxide, nitrogen dioxide and oxides of nitrogen, particulate matter (PM10 and PM2,5), lead, benzene, carbon monoxide and ozone

1.   Reference method for the measurement of sulphur dioxide

The reference method for the measurement of sulphur dioxide is that described in EN 14212:2012 ‘Ambient air — Standard method for the measurement of the concentration of sulphur dioxide by ultraviolet fluorescence’.

2.   Reference method for the measurement of nitrogen dioxide and oxides of nitrogen

The reference method for the measurement of nitrogen dioxide and oxides of nitrogen is that described in EN 14211:2012 ‘Ambient air — Standard method for the measurement of the concentration of nitrogen dioxide and nitrogen monoxide by chemiluminescence’.

3.   Reference method for the sampling and measurement of lead

The reference method for the sampling of lead is that described in Section A(4) of this Annex. The reference method for the measurement of lead is that described in EN 14902:2005 ‘Standard method for measurement of Pb/Cd/As/Ni in the PM10 fraction of suspended particulate matter’.

▼M1

4.   Reference method for the sampling and measurement of PM10

The reference method for the sampling and measurement of PM10 is that described in EN12341:2014 ‘Ambient Air — standard gravimetric measurement method for the determination of the PM10 or PM2,5 mass concentration of suspended particulate matter’.

5.   Reference method for the sampling and measurement of PM2,5

The reference method for the sampling and measurement of PM2,5 is that described in EN12341:2014 ‘Ambient Air — standard gravimetric measurement method for the determination of the PM10 or PM2,5 mass concentration of suspended particulate matter’

▼C1

6.   Reference method for the sampling and measurement of benzene

The reference method for the measurement of benzene is that described in EN 14662:2005, parts 1, 2 and 3 ‘Ambient air quality — Standard method for measurement of benzene concentrations’.

▼M1

7.   Reference method for the measurement of carbon monoxide

The reference method for the measurement of carbon monoxide is that described in EN 14626:2012 ‘Ambient air — Standard method for the measurement of the concentration of carbon monoxide by non-dispersive infrared spectroscopy’.

8.   Reference method for measurement of ozone

The reference method for the measurement of ozone is that described in EN 14625:2012 ‘Ambient air — Standard method for the measurement of the concentration of ozone by ultraviolet photometry’.

B.   Demonstration of equivalence

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. In that event the results achieved by that method must be corrected to produce results equivalent to those that would have been achieved by using the reference method.

2.

The Commission may require the Member States to prepare and submit a report on the demonstration of equivalence in accordance with paragraph 1.

3.

When assessing the acceptability of the report mentioned in paragraph 2, the Commission will make reference to its guidance on the demonstration of equivalence (to be published). Where Member States have been using interim factors to approximate equivalence, the latter shall be confirmed and/or amended with reference to the Commission's guidance.

4.

Member States should ensure that whenever appropriate, the correction is also applied retroactively to past measurement data in order to achieve better data comparability.

C.   Standardisation

For gaseous pollutants the volume must be standardised at a temperature of 293 K and an atmospheric pressure of 101,3 kPa. For particulate matter and substances to be analysed in particulate matter (e.g. lead) the sampling volume refers to ambient conditions in terms of temperature and atmospheric pressure at the date of measurements.

E.   Mutual recognition of data

▼M1

When demonstrating that equipment meets the performance requirements of the reference methods listed in Section A of this Annex, the competent authorities and bodies designated pursuant to Article 3 shall accept test reports issued in other Member States provided that the test laboratories are accredited to the relevant harmonised standard for testing and calibration laboratories.

The detailed test reports and all the results of the tests shall be available to other competent authorities or their designated bodies. Test reports shall demonstrate that the equipment meets all the performance requirements including where some environmental and site conditions are specific to a Member State and are outside the conditions for which the equipment has been already tested and type approved in another Member State.
