Radiant Panel Fire Tests on Cellular Plastics Insulation

Following the introduction in the Australian Model Uniform Building Code of a general limitation on materials, according to their performance in the "Test for Early Fire Hazard Properties of Materials" (AS 1530 Part 3), a range of rigid cellular plastics and systems used for insulating buildings has been subjected to this test. It was found that additional observations to those required by the standard were necessary to gain an understanding of product behaviour. The influence of specimen restraint and the need to consider all indices when assessing product performance are also discussed.
