Abstract

The paper examines the basis of the NFPA, British and ISO/CEN fan integrity testing and hold time standards. It is found that the most appropriate leakage area definition for integrity testing is Equivalent Leakage Area in CAN/CGSB-149.10-M86. Differences between the standards are discussed, an error in the NFPA standards is described, and other changes to the standards are recommended. Areas for further research are proposed to enable the errors in calculated hold times to be estimated with confidence and, if necessary, reduced.
