3、glowing of the test specimen, the duration of said flaming and glowing shall be noted and recorded. Dripping of molten and/or flaming material and igniting of the layer of cotton, if occurring, shall be noted and recorded. 4.6.3 To distinguish between flaming and glowing, a small piece of surgical c

4、otton (50 millimeters square) shall be brought into the area in question. Ignition of the cotton shall be indicative of flaming. 4.7 The flame shall be reapplied for 10 seconds in accordance with 4.5 and 4.6. The flame shall be immediately applied after the first application or when the flaming or g

5、lowing ceases to exist, if occurring on the first application. 4.8 If the test specimen drips molten and/or flaming material during the flame application, the burner may be tilted to an angle up to 45 degrees and slightly removed to the specimen side to avoid material dripping into the burner tube.

6、4.8.1 The 9.5 millimeters (0.38 inch) distance between the bottom of the test specimen and top pf the burner tube shall be maintained. 4.8.2 Any molten “strings“ of material are to be ignored and the flame is to be applied to the major portion of the specimen. 4.9 Charring, melting etc., of the test

7、 specimen shall be ignored. 5 Details to be specified The following details shall be specified in the referencing document: 5.1 Configuration to be tested 5.2 Conditioning classification 5.3 Requirements 5.4 Clamping technique 5.5 Final measurements and requirements 5.6 Flame application time, if ot
