O'dogherty, M.J. and Young, R.A., 1965. THE PERFORMANCE OF AUTOMATIC SPRINKLER SYSTEMS PART I - THE EFFECT OF CEILING HEIGHT, RATE OF FIRE DEVELOPMENT, AND SPRINKLER POSITION ON RESPONSE TO A GROWING FIRE. Fire Research Notes 601
ABSTRACT
This report descibes experiments in which wooden crib fires, developing at various rates, were burnt below a joisted ceiling. Sprinkler heads were mounted in a bay between joints and also below a joist. Continuous measurements were made of air temperature and sprinkler bulb temperature during the fire development. The size of fire at sprinkler operation was determined for a range of ceiling heights, horizontal distances of sprinklers from the fire axis, and depths of sprinkler mounting below the soffit of the ceiling or joist.
