BS EN 16738:2015

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:

• SO ₂;

• NO _x;

• 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.
