COMBUSTIBILITY EVALUATION METHOD OF SEAL MATERIAL FOR MULTIPLE GLASS

PROBLEM TO BE SOLVED: To provide a combustibility evaluation method for a seal material for multiple glass which becomes a rough indication of evaluation in screening and selection of a seal material configuring a fireproof multiple glass.SOLUTION: In a combustibility evaluation method for a seal material for multiple glass, at first, a switch 48 of a ceramic hot plate 32 is turned on to start the temperature rise of a heating face 34. Thereby, a sample 36 is gradually heated. Then, at the time of the temperature displayed in a display 50 of the ceramic hot plate 32 exceeding 300°C, a burner 46 is ignited, its flame 52 is held up above the sample 36 via a slit 44, and the temperature rise of the sample 36 is continued in this state. When the temperature of the sample 36 rises from 300°C, combustible gas is generated from the sample 36 and the generated combustible gas is ignited by the flame 52. When generation of continuous "flaming" is started, a temperature displayed in the display 50 is read and this value is recorded as a temperature at which the sample 36 flames, thus evaluating the flaming temperature of the sample.
