specimen rack (b，校服燃燒速率測定儀生產(chǎn),， fig. 2). the specimen rack provides supports for the

frames in which the specimens are mounted. the angle of inclination is 45°. two

guide pins projecting downward from the cct of the base of the rack travel

in slots provided in the floor of the chamber so that adjustment can be made

for the thickness of the specimen in relation to the flame front. a stop is

provided in the base of the chamber to assist in adjusting the ition of the

rack.
