1、Designation: D6413/D6413M 15Standard Test Method forFlame Resistance of Textiles (Vertical Test)1This standard is issued under the fixed designation D6413/D6413M; the number immediately following the designation indicates theyear of original adoption or, in the case of revision, the year of last rev
2、ision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method is used to measure the vertical flameresistance of textiles.1.1.1 As a part of the measure of flame resistanc
3、e, after-flame and afterglow characteristics are evaluated.1.2 This standard shall be used to measure and describe theresponse of materials, products, or assemblies to heat and flameunder controlled laboratory conditions and shall not be used todescribe or appraise the fire hazard or fire risk of ma
4、terials,products, or assemblies under actual fire conditions.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningv
5、alues from the two systems may result in non-conformancewith the standard.1.4 This standard does not purport to address all of thesafety concerns, 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

Significance and Use5.1 This test method determines the response of textiles to astandard ignition source, deriving measurement values forafterflame time, afterglow time, and char length.5.2
12、The vertical flame resistance, as determined by this testmethod, only relates to a specified flame exposure and appli-cation time.5.3 This test method maintains the specimen in a static,draft-free, vertical position and does not involve movementexcept that resulting from the exposure.5.4 Test Method

16、on 14 for single-laboratory precision.5.4.1 If there are differences or practical significance be-tween reported test results for two laboratories (or more),comparative tests should be performed to determine if there isa statistical bias between them, using competent statisticalassistance. As a mini
17、mum, the test samples used should be ashomogeneous as possible, that are drawn from the materialfrom which the disparate test results are obtained, and that areassigned randomly in equal numbers to each laboratory fortesting. Other materials with established test values may beused for this purpose.
18、The test results from the two laboratoriesshould be compared using a statistical test for unpaired data, ata probability level chosen prior to the testing series. If a bias isfound, either its cause must be found and corrected, or futuretest results must be adjusted in consideration on the knownbias
19、.6. Apparatus6.1 Test Cabinet and Accessories, fabricated in accordancewith the requirements specified in Figs. 1-6. Galvanized sheetmetal or other suitable metal can be used. The entire insideback wall of the cabinet shall be painted black to facilitate theviewing of the test specimen and pilot fla
20、me.6.1.1 The test cabinet shall be set up in a laboratory hood orwith comparable equipment so that combustion gases can beremoved from the test lab environment. Precautions must betaken to minimize the draft through the laboratory hood whileFIG. 1 Test ApparatusD6413/D6413M 152testing. Open doors or
21、 windows are examples of unnecessarycauses of drafts and must be avoided. A ventilation smoke tubekit3may be used to check for the presence of drafts.6.2 Burner, equipped with a needle valve to adjust flameheight (see Fig. 4).6.2.1 The burner shall be constructed by combining a 10mm 0.38 in. inside
22、diameter barrel 76 6 6mm36 0.25 in.long with a base from an adjustable valve burner. A Tirrillburner is recommended, but a Bunsen burner modified toconform to this test method also will suffice.6.2.2 The pilot light tube shall have an inside diameter ofapproximately 1.5 mm 0.06 in. and shall be spac
23、ed 3 mm0.12 in. away from the burner edge.6.2.2.1 The pilot light tube shall be located vertically next tothe burner as shown in Fig. 4.6.2.3 Gas controls and connections shall be as specified inFig. 5. The solenoid valve shall be capable of being fullyopened or fully closed in less than 0.2 s and a
24、ctivated by anadjustable timer. Position the solenoid valve as close to theburner as possible using a 50 6 13 mm 2 6 0.5 in. length of6.5 mm 0.25 in. inside diameter, 13 mm outside diameter 0.5in. outside diameter methane safe hose (Fig. 6).
