This European standard specifies a test method for the determination of emissions resulting from the use of combustible air fresheners into indoor air by means of chamber operation according to EN ISO 16000 9. This standard defines specific testing conditions for the measurement of the emissions from combustible air fresheners which minimize the effect of the testing on the combustion process. This standard provides a measurement method for the determination of the following non-exhaustive list of target substances emitted directly from the burning process: - VOC; - Benzene; - Naphthalene; - Formaldehyde. The measurement method can allow the determination of other substances. This standard provides additional information on the optional measurement of the following substances: - SO2; - NOx; - CO.
