TOMSK, Jun 18  RIA Tomsk. Employees of the Faculty of Mechanics and Mathematics of Tomsk State University (TSU) offered non-contact fire resistance testing of wooden structures and building materials; the method involves the use of infrared camera, the press service of the university reported on Tuesday.

It is specified that the scientists conducted experiments to work off the method of infrared diagnostics in the study of the characteristics of ignition: they took a variety of building materials from wood (OSB, plywood, chipboard), covered with flame retardants. A constant heat flux from the radiator was directed to the samples and the moment of ignition  the appearance of flame on the surface was fixed.

"The main goal of the series of experiments was the creation of a method of working with an infrared camera and use it to assess the fire hazard characteristics of various materials. Observations obtained at TSU can serve as additional recommendations in developing fire hazard test methods for both building materials and flame retardants",  is said in the statement.

The results of the experiments were presented by TSU staff at the International Seminar on Fire and Explosion Hazards in St. Petersburg, which was attended by experts from 34 countries. The topics of the seminar included studies of the dynamics of fire, detonation, hydrogen safety, flammability of materials and other aspects related to uncontrolled burning during fires and explosions, adds the press service.
