Scope1.1 This specification is intended to prescribe minimumsafety requirements for candles to provide a reasonable degreeof safety for normal use with candles, thereby

3、 improvingpersonal safety and reducing fires, deaths, and injuries.1.2 This specification is not intended to replace otherimportant safety practices that should be in place, such as adultsupervision, close monitoring, fire detection, alarm or suppres-sion systems, and use of candles away from combus

4、tiblematerials.1.3 Flame-producing devices, such as candles, present apotential hazard to the user. This specification cannot eliminateall hazards, but will minimize the potential hazards of candlesto the user.1.4 This specification is used to measure and describe theresponse of materials, products,

5、 or assemblies to heat andflame under controlled conditions, but does not by itselfincorporate all factors required for fire hazard or fire riskassessment of the materials, products, or assemblies underactual fire conditions.1.5 This standard is used to predict or provide a quantitativemeasure of th

6、e fire hazard from a specified set of fire conditionsinvolving specific materials, products, or assemblies. Thisassessment does not necessarily predict the hazard of actualfires which involve conditions other than those assumed in theanalysis.1.6 Fire testing is inherently hazardous. Adequate safe-g

7、uards for personnel and property shall be employed inconducting these tests.1.7 This specification states values in SI units which are tobe regarded as the standard. The values given in parenthesis arefor information only.1.8 This specification does not purport to address all of thesafety concerns,

8、if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory requirements prior to use.2.

Safety Requirements4.1 Safety Requirements for Flame HeightThis safetyrequirement applies to all candles except candles intended to bebu

22、rned outdoors.4.1.1 Rationale:4.1.1.1 Candle flame heights are burn characteristics thatshall be monitored closely by manufacturers, consumers,retailers, and anyone associated with the distribution and use ofcandles.4.1.1.2 Excessive candle flame heights can increase the riskof fires when using cand

23、le products.4.1.1.3 The 76.2-mm (3.0-in.) maximum allowable flameheight requirement for all candles excluding Easter, Paschal,sacramental, altar, and outdoor candles is, in part, based on theestablished requirement for nonadjustable, non-windprooflighters contained in Consumer Safety Specification F

24、400,taking into account certain differences in measurement meth-ods and other candle performance considerations not relevantto fire safety. In addition, candle flame heights are not static.The natural tendency of a candle is for the flame height to varyduring the burn life. The maximum allowable fla

25、me heightrequirement in this specification takes into account suchvariation and anticipates that manufacturers will design candlesto ensure that they remain below the maximum flame heightrequirement throughout the burning period. Furthermore, themanufacturer shall determine the appropriate lower fla

26、meheight for optimum performance for individual candle types.4.1.1.4 The 95.3-mm (3.75-in.) maximum allowable flameheight requirement for Easter, Paschal, sacramental, and altarcandles is larger than other candles because visibility of theflame during services at the place of worship warrants slight

27、lylarger flame heights.4.1.2 Performance Requirement:4.1.2.1 Candle flame heights (other than those of Easter,Paschal, sacramental, altar, and outdoor candles), when testedin accordance with the test method in 5.2, shall not exceed 76.2mm (3.0 in.). If at any time during the testing period the flame

28、height exceeds 76.2 mm (3.0 in.), extinguish that candle andrecord it as a failure.4.1.2.2 Easter, Paschal, sacramental, and altar candle flameheights, when tested in accordance with the test method in 5.2,shall not exceed 95.3 mm (3.75 in.). If at any time during thetesting period the flame height

29、exceeds 95.3 mm (3.75 in.),extinguish that candle and record it as a failure.4.1.2.3 For filled candles, if at any time during the testingperiod, regardless of flame height, the container cracks orbreaks, it shall be recorded as a failure.4.2 Safety Requirements for Secondary IgnitionThissafety requ

30、irement applies to all candles and ensembles withthe exception of Easter, Paschal, and sacramental candlesspecifically designed to be used during the service at the placeof worship.4.2.1 Rationale:4.2.1.1 Potential hazards associated with secondary ignitionsources in and on candles exist, especially

31、 if the candle is notdesigned properly. The ignition of material other than theintended wick(s) may result in damaged candles, elevated fuelpool temperatures, excessively rapid base material consump-tion, and unintended flames. All of these conditions could leadto potential fire hazards.4.2.1.2 This

32、 requirement describes the method to determinethe tendency of candles to support ignition at points other thanthe intended wick(s) that are integrated into the candles toenable them to burn.4.2.2 Performance Requirement:4.2.2.1 When the candle is tested in accordance with 5.2 ofthis specification, n

33、o secondary ignition shall occur.4.2.2.2 Record the candle as passing the secondary ignitionspecification if no secondary ignition is observed during thetesting.4.3 Safety Requirements for End of Useful LifeThis safetyrequirement applies to all votive, freestanding, and filled(including tealights) c

34、andles and to all ensembles containingtealights. This safety requirement does not apply to candlesrequiring a holder to keep them upright, birthday candles, andcandles intended to float on water.4.3.1 RationaleWhen the candle meets the safety require-ments for the end of useful life, this will reduc

35、e the risk of fires.4.3.2 Performance Requirement:4.3.2.1 Record votive and filled (including tealights) candleor tealight ensembles as passing the end of useful life require-ment when tested in accordance with the test method in 5.2 ifthe candle or tealight ensemble meets the definition in 3.2.6F24

36、17 112and does not break or crack the container, does not exhibitexcessive flame height, and does not exhibit secondary ignitionas detailed in this specification.4.3.2.2 Record the freestanding candle as passing the end ofuseful life requirement when tested in accordance with the testmethod in 5.2 i

37、f the candle meets the definition in 3.2.6 and theflame does not impinge on the supporting surface, does notexhibit excessive flame height, does not exhibit secondaryignition as detailed in this specification, and does not tip overon its own accord when tested on a level surface in accordancewith 5.

38、2.NOTE 1The use of current processes or devices that limit the candle8sability to consume all of the available fuel is offered as a way to reducecandle fires that occur at the end of the candle8s life. This does notpreclude the development of other suitable means to meet the require-ments set forth

39、in 4.3-4.3.2.2. This reduces heat buildup at the end of lifeand the possibility of secondary ignition, candle flashover, and containerfailure. While it is understood that current processes and devices will notguarantee that all fuel will not be consumed, the anticipated benefit inreducing candle fir

40、es warrants their consideration for use.4.4 Safety Requirements for StabilityThis safety require-ment is intended to cover freestanding candles that are nor-mally used without the aid of a holding device to keep themupright, filled candles (including tealights), and ensembles.Candles requiring a hol

41、der to keep them upright and votivecandles are excluded unless they are incorporated in anensemble. Easter, Paschal, sacramental, and altar candlesspecifically designed for use during the service at the place ofworship are also excluded from the requirements of thissection.4.4.1 RationaleThis requir

42、ement is intended to minimizethe hazards of candle tip over.4.4.2 Performance Requirement:4.4.2.1 Candles specified in 4.4 must not tip over whenplaced on a minimum 10.0 incline when tested in accordancewith 5.3 in this specification.4.4.2.2 Asymmetrical candles must pass this requirement ifthey do

43、not tip over when rotated around the candles verticalaxis and tested on the incline apparatus in all orientations inaccordance with 5.3.4.4.2.3 Candles must remain stable when tested on a levelsurface in accordance with 5.2 and not tip over at any timeduring the candle burning performance test.4.5 S

44、afety Requirements for Plastic Containers (IncludingTea Light Cups)This requirement applies to all plasticcontainers used for candles. Containers constructed of non-combustible materials are exempt from this test.4.5.1 RationalePlastic containers used for candle applica-tions are intended to be used

45、 in close proximity to an openflame. A wide variety of materials are used to manufactureplastic containers, some of which are inappropriate and cancatch fire resulting in a potential candle fire hazard. Whenplastic containers meet this requirement for flammability therisk will be reduced of the cont

46、ainer igniting while in use andcontributing to a candle fire.4.5.2 The plastic containers specified in 4.5 must have atotal burn time less than or equal to 300 s with no single burntime event exceeding 30 s when the containers are tested inaccordance with the method in 5.4 of this standard.5. Test M

47、ethods5.1 Candle fire safety issues intended to be monitored bythese test methods include flame height, secondary ignition,end of useful life, and stability.5.2 Candle Burning Performance Test:5.2.1 Summary of Test MethodCandle wicks are trimmedin accordance with the labels instructions. If no infor

48、mation isprovided on the label, the wicks are not trimmed for this test.All candles except tealights, tealight ensembles, and gel-containing candles are lit and allowed to burn for 4 h withperiodic observation. Gel candles and candles containing anygel materials shall be lit and allowed to burn for

49、8 h withperiodic observation. This procedure is repeated until the endof the candles useful life. Flame heights are observed atspecified intervals and recorded at the end of each burn cycle.Flame heights shall be measured and recorded in millimetres(inches).5.2.2 Apparatus:5.2.2.1 Nonflammable measuring device graduated in mil-limetres (inches),5.2.2.2 Candle holder/glass (if applicable),5.2.2.3 Lighter, matches, or other source of ignition,5.2.2.4 Test surface-level, noncombustible, and5.2.2.5 Wick-trimming device.5.2.3 Safety HazardsWarningThere
