Review of Fan Integrity Testing and Hold Time Standards

摘要

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 recom- Mended.
