Fire Testing and Hazard Assessment for Flame Retardant Polymer Composites
Safety Science and Technology, EarlyView.Flame retardant polymer composites are now being evaluated with more than pass or fail flammability tests. Heat release, smoke, toxicity, and system‐level behavior are receiving more attention, and multi‐scale methods are being used to describe fire hazard under more realistic conditions.
