17、ioning 5 6 Procedure 5 7 Expression of results 5 8 Test report 6Page 3 EN 1399 : 1997 BSI 1998 1 Scope This European Standard specifies two methods for determining the resistance of resilient floor coverings to stubbed and burning cigarettes. 2 Principle 2.1 Method A. Resistance to stubbed cigarette

18、 A load is applied to a burning cigarette butt placed on the surface of a test piece. After cleaning, the surface is examined under specified light conditions for any visible changes. 2.2 Method B. Resistance to burning cigarette A burning cigarette is placed in full-length contact with the horizont

19、al surface of a test piece. After cleaning, the surface is examined for visible changes. 3 Apparatus and materials 3.1 Thermometer, to measure air temperature. 3.2 Chronometer, which reads to 1 s. 3.3 A device, shown in figure 1, consisting of: 3.3.1 A straight, seamless steel tube, of inner diamete

20、r of (49,8 ) mm and minimum wall thickness 0 +0,2 of 3,6 mm incorporating two guide pins (see figure 2). 3.3.2 A cylindrical brass weight, of diameter (49,5 ) mm, length (152 ) mm and mass 0 +0,2 0 +0,5 approximately 2,5 kg, incorporating two guide grooves and a lower indenter of diameter (16 ) mm a

21、nd 0 +1 length approximately 30 mm. 3.3.3 A turntable holder, for the test piece. 3.3.4 A frame, on which the parts of 3.3.1 and 3.3.2 are mounted. 3.4 Illumination device, comprising a lamp of correlated colour temperature 5 500 K to 6 500 K, mounted to give an intensity of light at the viewing pla

22、tform of (1 500 100) lx and in such a way as to illuminate the test piece vertically from above. The surroundings shall be neutral and darkened. The intensity of the light shall be checked frequently by the use of a luxometer. The lifetime of the lamp, as given by the manufacturer, shall not be exce

23、eded. 3.5 Rotary viewing table, which enables the test piece to be rotated so that it may be viewed from all directions under the standard illumination. 3.6 Materials 3.6.1 Three common brands of pale tobacco cigarette, without filter or mouthpiece, with round cross-section with diameter approximate

24、ly 8 mm and length approximately 70 mm. 3.6.2 Standard cleaning and stain removal products. 3.6.2.1 White cotton, in pad or cloth form. 3.6.2.2 Brushes, hard, unlikely to score the surface. 3.6.2.3 Denatured ethanol. 3.6.2.4 Abrasives, abrasive scouring pads, steel wool No.00 or scouring powder or a

25、brasive paper, grain size P240 or finer, used with water. 3.6.2.5 Special cleaning products, special products recommended by the floor covering manufacturers.Page 4 EN 1399 : 1997 BSI 1998 Key 1 Cylindrical brass weight 2 Indenter 3 Test piece 4 Test piece holder 5 Burning cigarette 6 Steel tube Fig

Steel tube with guide pins and cylindrical brass weight with guide groovesPage 5 EN 1399 : 1997 BSI 1998 4 Sampling and preparation of test pieces Take a representative sample from the available material. Take at least one test piece per type of cigarette, of minimum len

27、gth 100 mm and minimum width 100 mm at equal distances across the sample, the distance between the outer edge of the sample and the nearest edge of the test piece being at least 100 mm. 5 Conditioning Condition the test pieces and cigarettes at a temperature of (23 2) C and relative humidity of (50

28、5) % for a minimum of 48 h. Maintain them in these conditions until immediately prior to the test. 6 Procedure 6.1 General Use a substantially draught-free environment at room temperature, record the temperature when the test is carried out. Use at least one cigarette per cigarette brand. If tests a

29、re run concurrently, the spacing of the cigarettes shall be such that no mutual influence is possible. The mass per unit length of each cigarette shall be (0,14 0,02) g/cm. NOTE. If necessary, this may be achieved by tapping the cigarette vertically to compact the tobacco. 6.2 Method A. Stubbed ciga

30、rette test Light one end of a cigarette and draw air through it until 10 mm has been consumed. Place the smouldering cigarette in position on the surface of the test piece, ensuring that it is in full-length contact with the horizontal surface of the test piece, and that the glued seam of the cigare

31、tte is facing upwards. For floor coverings with profiled surfaces, place the cigarette on the stud or whatever raised profile is incorporated. Allow the cigarette to burn for a further 20 s. Apply the load, ensuring that the cylinder fits on the lighted cigarette butt. Rotate the test piece through

32、90 within 2 s and remove the load. If a cigarette extinguishes before burning for 20 s, repeat the test with a new cigarette placed in a new position. 6.3 Method B. Burning cigarette test Light one end of a cigarette and draw air through it until 10 mm has been consumed. Place the cigarette on the s

33、urface of the test piece, ensuring that it is in full-length contact with the horizontal surface of the test piece, and that the glued seam of the cigarette is facing upwards. For floor coverings with profiled surfaces, place the cigarette between the studs or whatever raised profile is incorporated

34、. Allow the cigarette to burn away for another 20 mm and then remove the remains of the cigarette from the surface of the test piece. If a cigarette extinguishes before burning for 20 mm, repeat the test with a new cigarette placed in a new position. 6.4 Cleaning and observation 6.4.1 Remove, if pos

35、sible, any combustion residue from the surface using cotton moistened with ethanol. After cleaning, examine the residual staining from a distance of approximately 800 mm at an approximate angle of 45 and from all directions, by slowly rotating the viewing table. 6.4.2 If a stain is visible, clean th

36、e surface using a cleaning product chosen from those listed in 3.6.2.2, 3.6.2.4 or 3.6.2.5 and examine as described in 6.4.1. Record the cleaning product used. 7 Expression of results For each of the cigarette brands express the results, after cleaning the surface according to 6.4.1 and 6.4.2, in te

37、rms of the ratings in table 1. The overall result for the test shall be the individual result which shows the severest damage (lowest rating) and this overall result shall be stated in the test report. Table 1. Presentation of results Rating Effect on surface of test piece 5 No visible change 4 Slig

38、ht change of gloss only visible at certain viewing angles and/or slight brown stain 3 Moderate change of gloss and/or moderate brown stain 2 Severe brown mark, but no destruction of surface 1 Blistering and/or destruction of surfacePage 6 EN 1399 : 1997 BSI 1998 8 Test report The test report shall c

39、ontain the following information: a) a reference to this standard, i.e. EN 1399 and the method used, i.e. Method A for a stubbed cigarette or Method B for a burning cigarette; b) a complete identification of the product tested, including type, source, colour and manufacturers reference numbers; c) t

40、he previous history of the sample; d) the brands of cigarette used; e) temperature at which the test was carried out; f) the cleaning product used and description of the cleaning process; g) the overall result in accordance with clause 7; h) any deviation from the standard which may have affected th
