Purpose. The assessment of sensitivity of devices used and proposed for use during the testing of smoke optoelectronic spot fire detectors to smoke generated from various sources.
Methods. The study of information sources, applied standards, and methods for measuring sensitivity of fire smoke detectors, development of a specialized test stand, conducting studies at a specialized stand and analysis of the obtained results.
Findings. The results of studies of the characteristics of the air environment during smoke generation with glowing cotton, wood smouldering, and from test aerosols are presented.
Application field of research. Test laboratories of manufacturers of fire smoke detectors and accredited certification centers.
