Abstract
The thesis focuses on the effect of wood density on the results of fire tests. Wood (spruce wood in particular) is one of the most commonly used materials in many sectors - building constructions, furniture manufacture etc. With such a broad application, its fire technical properties must not be neglected. Fire retardants should be therefore used to prevent the fire from occurring and spreading.
Highlights
This physical property affects all technological processes as well as mechanical properties [4,1]
Regardless of evaluation methodology if the change in weight or thermal properties are used as the evaluation criteria, density may affect the final results of measurements
Our goal is to find out whether the density of test bodies has an effect on the overall result even with fire retardant treated samples
Summary
This physical property affects all technological processes as well as mechanical properties [4,1]. It has a direct impact on the production of components and parts for wooden constructions. Wood density has an impact on other aspects of wood evaluation and its properties i.e. evaluation of firetechnical proprieties and retarding adjustments. Regardless of evaluation methodology (standard test methods or conical calorimeter) if the change in weight or thermal properties are used as the evaluation criteria, density may affect the final results of measurements. Test methods almost always specify the parameters for wood moisture, air conditioning, thickness or quality of working, the parameters for density (limit values at least) are missing. This article aims to identify the effect of density of spruce wood test specimens on the results of the experiments
