Degradation of OSB exposed to the critical heat flux for determination of fire separation distances

Popis výsledku v původním jazyce

With increasingly dense urban structure and wider use of energy efficient (and very often combustible) materials both in and on walls, the requirements on fire separation distances become more actual than at any time in the past. Main parameter that affects separation distance its magnitude is radiation, critical heat flux respectively. The first approach was developed about 60 years ago. Critical heat flux used for the separation distance determination in the Czech Republic and Slovakia, highest in comparison with other countries, predicts the autoignition of exposed wooden materials in approximately 10 minutes. In the article a set of medium-scale fire experiments were conducted to verify this assumption. Wooden-based boards, namely oriented strand boards (OSB), were exposed to the critical heat flux of radiant panel of given power and time to ignition was measured. In this preliminary study, four scenarios were conducted using both insulated and uninsulated board with and without piloted ignition.
