3、7ISBN 0 580 41288 1National forewordThis British Standard is the UK implementation of EN 13773:2003.The UK participation in its preparation was entrusted to Technical Committee TCI/63, Burning behaviour of textiles.A list of organizations represented on this committee can be obtained on request to i
4、ts secretary.This standard references BS EN 1101:1996 and BS EN 13772:2003 for test methods. These three standards are closely related and must be read in conjunction for a full understanding of the test methods and classification.Since publication a number of issues have been raised with regards to
5、 technical aspects of the standards. The UK committee is concerned that some of these issues could result in test results being challenged. The main concerns are:(a) Difficulties have been reported in calibrating the electric radiator as required by Clause 7 of BS EN 13772:2003. This creates a devia
6、tion from the method that needs to be declared in test reports issued by laboratories accredited to BS EN ISO/IEC 17025:2005.(b) The behaviour of some fabrics under test is such that they cannot be said to conform with the requirement in subclause 10.7 of BS EN 13772:2003 (“the specimen shall still
7、be under radiation and remain so during the whole test”). This specifically has been found to apply to thermoplastic materials which melt away from the heat source and so can no longer be deemed to “. still be under radiation and remain so during the whole test”.(c) Subclause 4.1.1 of BS EN 13773:20
8、03 modifies the test method BS EN 1101:1996 by introducing a series of shorter flame application times. The fire resistance chemistry of some fabrics is such that they can fail the test at a short flame application time but pass at a longer flame application time. Consequently the information given
9、in the classification scheme can be misleading.(d) The cleansing procedure given in subclause 8.2 of BS EN 13772:2003 is not intended to demonstrate durability of the fire retardancy of the fabric. This leaves it uncertain whether fabrics would be “fit for purpose” for some applications.The UK commi
10、ttee is asking the responsible European Committee for a review of BS EN 1101-1996, BS EN 13772:2003 and BS EN 13773:2003 to address these concerns. Until such time as this review takes place and the standards are amended, users are advised to treat test results with caution. BS 5867-2:1980 remains c
11、urrent as a standard for testing curtains and drapes using a small ignition source.This publication does not purport to include all the necessary provisions of a contract.

20、dorsement, at the latest by August 2003, and conflicting national standards shall be withdrawn at the latest byAugust 2003.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium
21、, Czech Republic, Denmark, Finland,France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,Slovakia, Spain, Sweden, Switzerland and the United Kingdom.EN 13773:2003 (E)4IntroductionThe method described in this European Standard is one of four close
22、ly related methods for testing and classifyingtextile fabrics intended for curtains and drapes and similar uses such drapes and hangings, where classification isrequired.This method defines a classification scheme for curtains and drapes using ignitability and flame spread propertiesof vertically or
23、iented textile fabrics in response to flame contact under controlled conditions.This classification scheme is based on the assessment of ease of ignition and flame spread using two ignitionsources with a different heat intensity.EN 13773:2003 (E)51 ScopeThis European Standard specifies a classificat
24、ion scheme for the burning behaviour of vertically oriented fabricsintended for curtains and drapes and similar uses such as blinds and textile hangings, where classification isrequired. Untested materials are not classified.2 Normative referencesThis European Standard incorporates by dated or undat
25、ed reference, provisions from other publications. Thesenormative reference are cited at the appropriate places in the text and the publications are listed hereafter. Fordated reference, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorp
26、orated in it by amendment or revision. For undated references the latest edition of thepublication referred to applies (including amendments).EN 1101, Textiles and textile products - Burning behaviour - Curtains and drapes - Detailed procedure to determinethe ignitability of vertically oriented spec

28、ically oriented specimens with large ignition source3 Principle for the classification schemeThe classification scheme is based on the measurement of ignitability and flame spread according to the relevantEuropean test methods.The flame spread of the materials that are ignited by the small flame sou
29、rce is measured with this same ignitionsource. The flame spread of materials that will not ignite with the small source is measured with the more severeignition source. Ignitability and flame spread leads to a classification scheme with five classes.4 Test methods and criteria used4.1 Ignitability o
30、r ease of ignition4.1.1 Test methodThe classification scheme refers to the edge ignition test of EN 1101, modified by starting with 1 s flame applicationtime and increasing the ignition time by 1 s steps up to 5s and then by 5s steps up to 20 s if no ignition occurs.4.1.2 CriteriaThe main criterion
31、considered for classification is ignition/non ignition.4.2 Flame spread4.2.1 Test methodThe classification scheme refers to the edge ignition tests of EN 1102 and EN 13772.EN 13773:2003 (E)64.2.2 CriteriaFlaming debris, flame spread as measured by the severance of first and third marker threads.5 Cl
