The National Building Code of Canada provides architects, engineers and builders with a simple, practical calculation method for assigning fire‐resistance ratings to wood‐frame and steel‐frame wall, floor and roof‐ceiling assemblies. It was originally devised in the early 1960s and is commonly known as the Component Additive Method (CAM). A collaborative industry–government research program was carried out recently at the National Research Council Canada to develop new fire‐resistance ratings for gypsum‐board protected walls. Forintek Canada Corp. and the Canadian Wood Council participated in that program on behalf of Canada's wood industry. As part of the research program, a number of full‐size fire‐endurance tests were carried out on wood‐frame and steel‐frame walls. The results of those fire tests have allowed us to revisit those sections of the Component Additive Method which are applicable to light‐frame walls lined with gypsum board. © 1997 John Wiley & Sons, Ltd.
