Emission safety of combustible air fresheners - Test methods
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.
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.

Emisijska varnost vnetljivih snovi v osvežilnikih zraka - Preskusne metode
Ta evropski standard določa preizkusno metodo za določevanje emisij v notranji zrak, ki so posledica uporabe gorljivih osvežilnikov zraka, in sicer s postopkom uporabe komore v skladu s standardom EN ISO 16000-9.
Ta standard določa specifične preskusne pogoje za merjenje emisij gorljivih osvežilnikov zraka, ki v kar največji meri zmanjšujejo vpliv preizkušanja na proces zgorevanja. Ta standard zagotavlja merilno metodo za določanje naslednjega neizčrpnega seznama ciljnih snovi, ki se izločajo neposredno v procesu zgorevanja:
— hlapne organske spojine (VOC);
— benzen;
— naftalen;
— formaldehid.
Z merilno metodo je mogoče določiti tudi druge snovi. Ta standard zagotavlja dodatne informacije o izbirnih meritvah naslednjih snovi:
— SO2;
— NOx;
— CO.
Ta standard ni primeren za količinsko opredelitev delcev. Ta standard ne velja za negorljive osvežilnike zraka in kadila. Ta standard ne vključuje dišečih sveč, katerih čas gorenja ne presega 2,5 ure.

EN 16738:2015 (E) 6 3.5 incense dried plants (herbs or wood) which are pulverized and mixed with resins Note 1 to entry: The sticks in incense sticks may be of sandalwood, bamboo or similar material that has the ability to burn together with the wrapped plant ingredients. Some incense mixtures are composed of dried and finely chopped herbs, woods and roots, others from resins and balsams as small pellets or granules. Incense may be mixtures but may also consist of one single type of incense based on single plants or plant parts. Besides, natural or synthetic essential oils can be added. Four common types of incense exist: loose incense (granulate or powder), cones, incense sticks with and without solid stick. 3.6 catalytic lamp system based on the catalytic combustion of a combustible liquid by using a catalytic burner composed of porous material which is made of synthetic or mineral materials Note 1 to entry: The product requires also a wick that feeds the burner from the liquid container by capillarity, a cap designed to stop operation of the catalytic lamp and openwork mounting for protection and ventilation. The catalytic lamp diffuses perfume and combustibles in the air. It perfumes and destroys smells, at the same time. 3.6.1 catalytic burner burner composed of a porous material made from synthetic or mineral material and a specific catalyst in the catalytic oxidation of solvent which favours the production of carbon dioxide and water 3.7 unit specific emission rate SERU product specific rate describing the mass of a volatile organic compound emitted per unit (U) of combustible air freshener per unit of time at a given time from the start of the test 3.8 burn rate BR mass of material burned per unit of time under test conditions 3.9 background of the test chamber emission level of the test chamber operated with all the equipment except the specimen 3.10 test specimen sample intended for emission testing in an emission test chamber 4 Test methods 4.1 Principles The principle of the test is to determine the unit specific emission rate (SERu) of emissions resulting from the use of combustible air fresheners. The test is performed under controlled conditions in an emission test chamber according to EN ISO 16000-9. The air in the emission test chamber is fully mixed and measurements of a substance concentration in the air at the test chamber outlet are representative of the emission test chamber concentrations for that substance. SIST EN 16738:2016
EN 16738:2015 (E) 7 Unit specific emission rates, SERU, at a given time, t, are calculated from the emission test chamber air concentrations, C, the air change rate, n, and number of test specimens at the same time in the test chamber, N. With knowledge of the concentration in the outlet air, the air flow through the emission test chamber and the number of the test specimens, the unit specific emission rates of emissions from the product under test can be determined. 4.2 Apparatus Dynamic environmental emission test chamber according to EN ISO 16000-9, and a suitable number of wire mesh cylinders type 2 according to EN 15426. 4.3 General test conditions 4.3.1 General Combustible air fresheners are ignited and burned in the test chamber using the parameters specified in Table 1 until a state of equilibration is reached. Dynamic emission test chamber according to EN ISO 16000-9 using inlet air at 23 °C and 50 % relative humidity with 2 air changes per hour. If the burn rates data outside the chamber are not available the data can be provided by a burning test run outside the test chamber and for candles it will be according to EN 15426 for the minimum testing time in the test chamber. The test protocol and test conditions of the chamber experiment are defined in such a way tha
