Closely connected to the development history of the candle are the efforts made to improve its quality and

16、 its safety in use. Discussions in the past and present over possible self-forming, harmful emissions and fires caused by unsafe candles and/or inappropriate use during the burning of candles have led to consumer concern for these issues. This European Standard helps to ensure a reasonable degree of

17、 safety during use, thereby improving personal safety and reducing the risk of fires, deaths and injuries. DIN EN 15493:2008-01 EN 15493:2007 (E) 5 1 Scope This European Standard specifies requirements and test methods for the fire safety of candles intended to be burned indoors. 2 Normative referen

20、f a burning period and pause 3.4 candle one or more combustible wicks supported by a material that constitutes a fuel, which is solid, semisolid or quasi-rigid at room temperature (20 C to 27 C) NOTE 1 It can also contain additives, which are used for colour, odour, stability, or to modify the burni

21、ng characteristics; the combined function of which is to sustain a light-producing flame. NOTE 2 Including candles with decoration attached to or contained within the candle. 3.5 container candle candle which is produced in and will be burned in a container 3.6 flame height base of the flame to the

22、top of the flame NOTE See Figure 1. DIN EN 15493:2008-01 DIN EN EN 15493:2007 (E) 6 Figure 1 Flame height 3.7 free-standing candle candle that is designed to be used without a supporting holder 3.8 molten fuel pool portion of the wax or fuel pool of a candle that is in liquid form when the candle is

23、 burning 3.9 re-ignition self-ignition of the wick after it has been extinguished 3.10 secondary ignition self-sustained flame other than that on the intended wick(s), including flash over where the base materials vapours ignite over the molten fuel pool 3.11 self-sustained flame flame that continue

24、s to burn until the fuel source is removed or depleted or requires manual extinguishing 3.12 tea light cylindrical candle that is burned up in a container which may be suitable to keep vessels containing coffee, tea or other liquids warm, by using a warming stove NOTE 1 Typical dimensions of a tea l

25、ight are 38 mm in diameter and 15 in mm height. NOTE 2 A tea light container can be made from metal, glass or plastic. 3.13 wax crystalline, plastic solid or semi-solid material at 25 C consisting of a mixture of hydrocarbons and/or hydrocarbon derivatives NOTE Wax melts typically at temperatures eq

26、ual to or greater than 40 C and becomes a low viscosity liquid. Waxes may be of mineral (particularly petroleum), vegetable, animal (including insect), or synthetic origin. 3.14 wick object that delivers fuel to a flame through the process of capillary action 4 Safety requirements 4.1 Stability Free

27、-standing candles shall not tip over when tested on a slope of 10 according to 9.2. DIN EN 15493:2008-01 DIN EN EN 15493:2007 (E) 7 4.2 Secondary ignition No secondary ignition shall occur for more than 10 s, when the candle is burned according to 9.3. NOTE Wick remaining in the molten fuel pool is

28、considered as a potential source for secondary ignition. 4.3 Flame height The flame height for all candle types, except tea lights, shall not exceed 75 mm. The flame height for tea lights shall not exceed 30 mm. Test method see 9.4. NOTE The natural tendency of a candle is for the flame height to va

29、ry during the burn life. The maximum allowable flame height requirement in this standard takes into account such variation and anticipates that manufacturers will design candles to ensure that they remain below the maximum flame height requirement throughout the burning. Furthermore, the manufacture

30、r should determine the appropriate lower flame height for optimum performance for individual candle types. 4.4 Behaviour by self-extinguishing at the end of the burning process Container candles and candles marketed as self-extinguishing shall, at the end of the burning time, self extinguish and, in

31、 the case of container candles, not cause the container to break. 4.5 Re-ignition after extinguishing The wick shall not continue to glow or smoke for more than 20 s after extinguishing. After extinguishing the candle shall not spontaneously re-light. For the test method see to 9.3. 5 Test equipment

32、 and apparatus 5.1 Incline plane (fixed or adjustable) with an angle of (10 0,2) from a horizontal level. 5.2 Measuring device, non flammable with millimetre grading. 5.3 Candle extinguisher, type “snuffer”. 6 Sampling The test shall be carried out on finished candles representative of those intende

33、d to be supplied commercially. For the test result to represent a specific candle type, a minimum of 3 samples shall be tested. 7 Sample preparation Remove any outer wrapping and label material and prepare the sample for use according to the manufacturers instructions, if any given, e.g. trim the wi

34、ck. For identification of the sample, measure the dimension and the mass of the candle. The temperature of the sample shall be (20 5) C before the test is started. 8 General test conditions The room temperature at which the burning test is to take place shall be (20 5) C. The room shall be draught f

35、ree. If during the test the temperature is outside the range, the maximum and/or minimum temperature shall be recorded in the test report. DIN EN 15493:2008-01 DIN EN EN 15493:2007 (E) 8 For testing of floating candles, the temperature of the water shall be (20 5) C when the test is started. NOTE Dr

36、aught free means that a candle burns without noticeable disturbance of the flame. If the flame is flickering this can be verified using a reference candle such as a paraffin with a diameter of 22 mm. If this candle also flickers there is a draught, if not then it is flickering due to the candle desi

37、gn or quality. 9 Test methods 9.1 General In the case of candle designs not catered for in the test procedures, the test should be carried out as far as possible as described and deviations from the test procedure shall be recorded in the test report. 9.2 Stability test Place the prepared, unlit can

38、dle on an incline plane (5.1) in the orientation most likely to cause tipping at (10 0,2) from level. Rotation around the candles vertical axis may be necessary to determine the stability of an asymmetrical candle. 9.3 Burning test Follow the instructions for use, if any. If no instructions are give

39、n, the following shall apply: Place each candle in an upright position on a heat resistant, non flammable surface. Non free-standing candles are placed in a suitable candleholder which does not affect the burning property of the candle. Free-standing candles are placed on a surface that does not aff

40、ect the burning property. Floating candles are placed in a suitable bowl filled with water. When testing multiple samples all candles, except for floating candles, shall be separated by the distance specified by the manufacturers instructions, see EN 15494:2007, Figure 3 (edge to edge). The specifie

41、d distance between samples does not apply to floating candles. Position the wick in an upright position and light the candle without contaminating the candle by the ignition source. Burn the candles according to the burn test cycle specified in Table 1. Use a candle extinguisher (5.3) to extinguish

42、candles. Table 1 Burn test cycles Type of candle Burn test cycle Floating candles, container candles and candles marketed as self-extinguishing with a mass below 40 g (including tea lights) Burn candle continuously until self-extinguishing. Floating candles and container candles with a mass above 40

43、 g Burn candle 4 h, pause for minimum 1 h. Continue to burn in cycles until self- extinguishing. Candles with a mass below 40 g (excluding floating candles and container candles) Burn candle continuously until a residual height of 10 mm. Candles with a mass above 40 g (excluding floating candles and

44、 container candles) Burn candle 4 h, pause for minimum 1 h. Continue to burn in cycles until a residual height of 20 mm. DIN EN 15493:2008-01 EN 15493:2007 (E) 9 Visual observations are made 5 min after ignition, at least at hourly intervals throughout the burning period, at extinguishing and self-e

45、xtinguishing, when applicable. 9.4 Flame height The flame height (whole visible part of the flame, see 3.6) is measured and recorded 5 min after ignition and before extinguishing in each burning period. If the flame appears to approach the maximum allowable flame height at other times, it shall also

46、 be measured and recorded. For candles with a total burning time less than one specified burning period, the flame height is measured and recorded at least twice. NOTE In a burning period where a candle is burning until self-extinguishing, the flame height will gradually become lower as the fuel sou

47、rce becomes depleted. This behaviour is to be considered when time for measuring the flame height, before end of life, is defined for this type of candle. 10 Test report The test report serves to identify the tested candle and to record the test results. The test report shall include the following d

48、etails: a) reference to the number and year of publication of this European Standard (EN 15346:2007); b) details of the test sample (e. g. identification, dimensions, mass); c) any defects identified during sample preparation; d) test results according to this European Standard; e) details of any deviation from this European Standard; f) name and address of the test facility; g) date of the test.
