This standard establishes uniform methods for laboratory testing of air curtain units to determine aerodynamic performance in terms of airflow rate, outlet air velocity uniformity, power consumption and air velocity projection for rating or guarantee purposes. This standard references 2012-01-01T00:00:00Z https://yse.yabesh.ir/std/handle/yse/170741 AMCA 210; Laboratory Methods of Testing Fans for Rating AMCA - Air Movement and Control Association Inc. This ANSI/AMCA standard defines uniform methods for conducting laboratory tests on housed fans to determine airflow rate, pressure, power and efficiency, at a given speed of rotation. This revision adds requirements for checking effectiveness of the airflow settling means and testing for chamber leakage, allows usage of a Star type straightener, and refines the conversion from in. wg to Pa. 2007-01-01T00:00:00Z https://yse.yabesh.ir/std/handle/yse/161503 AMCA 501; Application Manual for Air Louvers AMCA - Air Movement and Control Association Inc. Provides general information and comments on factors to be considered when designing or specifying installations requiring louvers. Serves as a guide to understanding the various types of louvers available and includes items to be considered to ensure their proper use. 2009-01-01T00:00:00Z
