18、6738:2015 (E) 4 1 Scope 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 measurem
19、ent 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
20、; 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 ma
21、tter. 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. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and

29、3.1 combustible air freshener product constituted by a fragranced combustible material which by action of combustion releases in the air smelling substances which it contains (e.g.: scented candle, incense, catalytic lamp, etc.) 3.2 candle one or more combustible wicks supported by a material that c
30、onstitutes a fuel, which is solid, semisolid or quasi-rigid at room temperature (20 C to 27 C), the combined function of which is to sustain a light-producing flame Note 1 to entry: It can also contain additives, which are used for colour, odour, stability, or to modify the burning characteristics;
31、including candles with decoration attached to or contained within them. 3.2.1 scented candle candle in the fuel of which a fragrance intended to be released is added 3.3 indoor air air within an enclosed space, e.g. dwelling or public building 3.4 scented oil lamp (for indoor use) container in which
32、 scented oil is burned at the wick BS EN 16738:2015EN 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 wra
33、pped 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, natur
34、al 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
35、 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
36、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 di

38、est 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 uni
39、t 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 concentrat
40、ion in the air at the test chamber outlet are representative of the emission test chamber concentrations for that substance. BS EN 16738:2015EN 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
41、 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
42、 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 par
43、ameters 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
44、 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 that standardized (well controlled) burning processes inside the cha
45、mber 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 candle is positioned; temperature; relative humidity; oxygen concentration. 4.3.2 Te
46、st chamber volume The test chamber volume shall be 1,0 m3 0,1 m3. Test chambers with larger volumes may be accepted provided that sufficient data support evidence of comparable results. Sufficient data requires a validation study with a minimum of 10 comparative tests between a 1 m3chamber and anoth
47、er chamber and successful participation in the Round Robin Test with a minimum of 5 participating laboratories. 4.3.3 Number of test specimens at the same time in the test chamber Number of test specimens as defined in Table 1.
