32,2 The burning time is to be calculated immediately upon ignition of the fusee.

32'3 At least two samples of each size and type of fusee are to be subjected to burning in both the upright (tilted 20 degrees), and the horizontal positions, All samples tested shall have burning times falling witiin the specified limits shown in Table 32.2.

33 lgnition Temperature Test

33'1 The ignition temperature of the igniter composition and the flare color composition shall be not less than 350'F (177'C).

33.2 The apparatus employod is to consist ossentially of a combustion chamber surrounded by a molten alloy bath heated by a spocial oloctric furnace having low resistance rod-type heating elements and thermostatic control, The combustion chamber is to consist of a heat resistant glass oi quartz flask of conical form with flat bottom 4.5 inches (1 1,4 cm) in height, 2,4 inches (6,0 cm) in diameter at the bottom, and 1,1 inches (2.8 cm) in diameter at the top, lt is to be about 5.41 ounces (160 ml) capacity, having a ratio of sudace area to volume of about 1:1, The temperature of the bath is to be measured by meanJof a calibrated thermocouple provided with a quaftz tube for protection of the hot junction, Tho thermocouple is to be held in the alloy bath so that its hot junction is about level with ths bottom of the combustion chamber and 114 inch (6.4 mm) from tho side of the chamber.

33.3 Small amounts of the material taken from at least two sample fusees aro to be dropped into the flask at intervals of g"F (5'C) and it is to be observed whether or not ignition is obtained, A little additional air may be introduced into the flask by means of a rubber bulb and a bent-glass delivery tube. After each trial, the gases, vapors, and residue are to be completely removed by the aid of a slow stream of air, The lowest temperature at which ignition occurs (without application of flame), which results in flamino or glowing combustion within 2 minutes, is to be taken as the ionition temperature, UL COPYRIGHTED MATERIAL -
