Laboratory Methods of Testing Jet Fans for Performance
This standard deals with the determination of technical characteristics needed to verify manufacturing of the specified performance characteristics of jet fans for longitudinal applications (e.g., thrust and airflow). It does not cover those fans designed for ducted applications, nor those designed solely for air circulation (e.g., ceiling fans and table fans). Additionally, the test procedures described in this standard relate to laboratory conditions only. The measurement of performance under in-situ conditions is not part of this standard.
