An evaluation has been made of the behaviour of selected phenolic resins and glass-reinforced phenolic composites in a number of fire test procedures which ranged from bench-scale to full-scale and assessed a number of fire hazard characteristics. It was concluded that all the tests had some deficiencies but that the ASTM E-1354 Cone Calorimeter was most suitable for use in research and development of new materials and that the ASTM Room Fire Test had good potential for assessing 'real-life' fire performance.
