scope:

NEN-EN 16738 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. This standard is not suitable for the quantitative determination of particulate matter. This standard does not apply to non-combustible air fresheners and loose incenses. Any scented candle with burning time shorter than 2,5 h is outside the scope of the standard.
