Experiments are described on the measurement and detection of smoke in a room 2.46 m (8ft 1in) high, having a volume of 153 m^3 (5400 ft^3). The fires were in wood cribs, rubber cribs, petrol and polyvinyl chloride powder, which were sited at a range of horizontal distances up to 6.10 m (20 ft) from the measuring and detecting equipment. Measurements were made of the optical density of the smoke, the rise in air temperature, and the response times of two types of proprietary smoke detector.
