Revision of the European Fan Efficiency Test Standard

Responding to criticism from other stakeholders, the European fan industry acknowledges a need to provide additional data describing the energy losses at partial-load operation. Rarely is a fan used at its best efficiency point. Standardization is required that describes the performance characteristics at other operating points. Standardized methodology can then be used by regulators to legislate product information requirements. This would also provide users with reliable data to make better informed decisions. This paper describes proposals from the European fan industry for a European standardization request (sReq) to revise or create a new standard.
