ANNEX VII

REFERENCE METHODS FOR ASSESSMENT OF CONCENTRATIONS OF BENZENE AND CARBON MONOXIDE Reference method for the sampling/analysis of benzene The reference method for the measurement of benzene will be the pumped sampling method on a sorbent cartridge followed by gas chromatographic determination that is currently being standardised by CEN. In the absence of a CEN standardised method, Member States are allowed to use national standard methods based on the same measurement method. A Member State may also use any other method which it can demonstrate gives results equivalent to the above method. Reference method for the analysis of carbon monoxide The reference method for the measurement of carbon monoxide will be the non-dispersive infra-red spectometric (NDIR) method, that is currently being standardised by CEN. In the absence of a CEN standardised method, the Member States are allowed to use national standard methods based on the same measurement method. A Member State may also use any other method which it can demonstrate gives results equivalent to the above method. Reference modelling techniques Reference modelling techniques cannot be specified at present. Any amendments to adapt this point to scientific and technical progress must be adopted in accordance with the procedure laid down in Article 6(2).
