3、oration. Consideration was given to garments and other such items intended for use by babies under the age of six (6) months. On the basis that babies of this age are not yet mobile, i.e. they are unable to crawl or walk, the risk was considered low. The principle upon which this standard is based i

4、s the acceptance that most, but not all, fabrics used in the manufacture of childrens nightwear will ignite when exposed to a small flame. On this premise therefore, there is no requirement for a specific ignitability test. The specification requires that the parameters of time of flame spread and s

5、urface flash are measured using a specified test procedure (EN 1103). The risk of fire may be diminished in some situations by the use of a suitable flame retardant. However, the application of a flame retardant could be considered to present a health risk. Both points of view were discussed in the

6、feasibility study, prepared under a Mandate (M/263) that preceded the Standardization Mandate. Following the publication and implementation of this standard in CEN countries, there should be an 18 month transition period from the date of availability, to allow manufacturers to develop and produce ga

7、rments that conform to the standards. The period is also to allow the supply chain, from manufacturer to the consumer, to be cleared on non-conforming garments. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement t

9、ited Kingdom. EN 14878:2007 (E) 4Introduction The aim of this European Standard is to define a harmonised procedure for the specification of childrens nightwear or fabrics intended for childrens nightwear with regard to their burning behaviour. Within the scope of this specification it is not possib

10、le to cover all the potential hazards that may create an unsafe garment; conversely, indefinable specific hazards in certain styles/design of garment may not present a risk. It is therefore recommended that an individual risk assessment is carried out on any garment in order to ensure that it does n

11、ot present a hazard to the wearer and can therefore be deemed to be a safe garment. This includes the use of applied flame retardant treatments. Durability of such finishes will require assessment. No European Standard method addressing durability of such treatments has yet been established. EN 1487

12、8:2007 (E)51 Scope This European Standard specifies requirements for the burning behaviour of childrens nightwear and nightwear fabrics intended for such garments when tested in accordance with EN 1103 but without the washing procedure. 2 Normative references The following referenced documents are i

18、abric assembly series of fabrics assembled as they would be at the garment manufacturing stage (excluding threads and trimmings), for the purpose of testing 4 Principle The properties of time of flame spread and surface flash are evaluated by submitting a sample to the application of a specified tes

19、t method contained in EN 1103. EN 1103 contains a cleansing procedure which is not applied to any test material covered by this standard as a single wash has been found to have little or no effect on finishes used on nightwear. 5 Toxicology of flame retardant A flame retardant is a substance used to

20、 impart improved fire behaviour to a material. When a flame retardant is applied to a textile to be used in nightwear conforming to this standard, it will be the responsibility of the manufacturer/retailer placing the chemically treated flame retardant nightwear on the European market to ensure the

21、finish being used has been adequately assessed for risk of toxicity and/or eco toxicity and is considered safe for its intended use by the EU Scientific Committee on Health and Environmental Risks (SCHER).Any flame retardant used to impart a degree of reduction of any of the measured parameters shal

22、l be able to provide this reduction during the expected life of the garment. It shall therefore be able to resist the normal washing procedures to which the garment could reasonably be expected to be subjected. 6 Fabric and garment sampling 6.1 Fabrics 6.1.1 At least one sample shall be taken that i

23、s representative of the bulk, of sufficient size to provide the specimens for the test. Three specimens shall be taken in the machine direction and three specimens in the cross direction. 6.1.2 Where multi-layer fabrics or fabric assemblies are tested, they should be tested in the arrangement which

24、is to be used in the garment. The order of the layers in the test specimen and the face to which the test flame is applied, should be noted in the test report. 6.2 Fabric from garments The specimens can be taken from one or more styles of garments made of the same fabric and finishing route. 6.3 Sho

25、rtage of material If it is not possible to obtain a single test specimen of the size required in EN 1103, pieces shall be joined, cut from the same or different garments of the same type, in the same direction, using butt joints held together with five equally spaced staples across the width of the

26、specimen. Overlapping joints shall not be used and no more than three pieces are to be used to form any one specimen. This should be noted in the test report. EN 14878:2007 (E)76.4 Range testing 6.4.1 Conventional testing allowing the characterization of the sensitivity of the product with regard to

27、 the fire behaviour taking into account the variation of one or more parameters (i.e. mass per unit area; colour; surface appearance; volumic mass etc) from a reduced number of test specimens determined after evaluation provided that the results obtained on the various samples give the same results.

28、 6.4.2 The range testing can be carried out on a component of the range, representing the most unfavourable cases. For example, when a material exists in several colours, with different surface appearances, the result of the testing can be applied to the range, based on the results of tests carried

29、out on some appearances and colours, from the complete range provided. 7 Test method The measurement of time of flame spread and surface flash shall be carried out in accordance with EN 1103. All test procedures are to be completed on the garment/fabric as received. All test procedures are to be com

30、pleted on the garment/fabric without washing or otherwise cleansing (see Clause 4). 8 Number of tests 8.1 General For a nightwear product (see 3.1) or nightwear fabric to claim a particular class, all the relevant criteria given in Table 1 Class A or B shall be met. 8.2 Flame spread and surface flas

31、h 8.2.1 For the compliance parameters of time of flame spread and surface flash, the selection of the class is based on the results of tests in accordance with EN 1103. 8.2.2 If at least two specimens (out of six) give a result belonging to a lower class, the material shall belong to this lower clas

32、s. 8.2.3 If only one specimen (out of six) gives a result belonging to a lower class, three extra specimens shall be tested in the same direction as the one giving the worst result. 8.2.4 If none of the extra three specimens gives a result belonging to the higher class, the material belongs to the o

33、riginal class. 8.2.5 If at least one of the extra three specimens tested gives a result belonging to the lower class, then the material belongs to the lower class. 9 Requirements For the purposes of this standard, the various categories of nightwear fabrics are classified as in Table 1. It is assume

34、d that the satisfaction of a higher class will satisfy all the criteria of the lower classes.

44、N 14878:2007 (E)11Annex B(informative) Design guidance B.1 The garment style and design can have a significant effect on the risk of ignition and burning behaviour of garments and the consequent severity of injury to the wearer. Thus, a risk assessment should be undertaken as part of garment design,

45、 taking into account factors such as the following: a) close fitting garments are less likely to come into contact with flames and, even when ignited, may burn less rapidly because they trap less air to feed the fire; b) trims, motifs and prints may change the burning characteristics of a garment, p

46、otentially reducing the level of safety offered by the basic fabric class; c) long, loose sleeves are a potential hazard, for example when cooking; d) full skirts increase the potential for ignition from open fires. They also contribute to the chimney effect, increasing the potential burns area, if a garment is ignited. Belts or other forms of waist restriction may reduce this effect. B.2 Where an aspect of design is considered to have a potential impact on the flammability of the garment and injury to the wearer, action should be taken to modify the design. EN 14878:2007 (E)
