DIN EN 16738:2016-04EN 16738:2015 (E) 4 1 Scope This European standard specifies a test method fo
23、r 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 e
24、ffect 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 determi
25、nation 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
26、loose incenses. Any scented candle with burning time shorter than 2,5 h is outside the scope of the standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

37、(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 dri
38、ed 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
39、 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
40、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 des

43、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 u
44、se 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 t
45、he emission test chamber concentrations for that substance. DIN EN 16738:2016-04EN 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 th
46、e 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 tes
47、t 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 i
48、s 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
49、 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 that standardized (well controlled) burning processes inside the chamber are guaranteed. Parameters to be controlled are: air mixing inside the chamber; avoidance of disturbance of the flame, burning in draught free conditions and no flickering; composition of the stand on which the can
