Analysis of Flame Retardancy in Polymer Science is a scientific/practical book that is conceptualized, designed, and written for students, early-career researchers, and junior engineers to explain the basic principles of fire analysis/characterization methods/methodologies, from flammability, ignition, and fire spread to forced convection and related analyses and to elucidate the mechanisms underlying flame retardancy in both gas and condensed phases followed by correlation between laboratory- and real-scale fire analyses as well as fire analysis from an industrial standpoint. This book is also an indispensable resource for identifying and mounting the latest achievements in fire analysis/characterization methods to frame the effects of fire evaluation strategies to be utilized for research and development. The book also gives a broad description of fire analysis related to different standards and regulations for different applications in different geographic zones.
