ISO 27327-1:2009建立了空气幕装置实验室测试的统一方法，以确定空气流量、出口空气速度均匀性、功耗和空气速度投影方面的空气动力学性能，用于评级或保证目的。 ISO 27327-1:2009不适用于用于设计、生产或现场测试的测试程序规范。

ISO 27327-1:2009 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. ISO 27327-1:2009 is not applicable to the specification of test procedures to be used for design, production or field testing.
