本标准为风扇或其他空气移动装置的实验室试验制定了统一的试验方法，以确定其空气动力学性能，包括气流速率、产生的压力、功耗、空气密度、旋转速度和效率，以达到额定或保证的目的。本标准适用于将空气用作试验气体时的风扇或其他空气移动装置，但以下情况除外:（a）空气循环风扇（吊扇、台式风扇）；（b） 正压呼吸机；（c） 带级间冷却的压缩机；（d） 容积式机器；（e）用于设计、生产或现场测试的测试程序。

This standard establishes uniform test methods for a laboratory test of a fan or other air moving device to determine its aerodynamic performance in terms of airflow rate, pressure developed, power consumption, air density, speed of rotation and efficiency for rating or guarantee purposes. This standard applies to a fan or other air moving device when air is used as the test gas, with the following exceptions: (a) air circulating fans (ceiling fans, desk fans);(b) positive pressure ventilators;(c) compressors with interstage cooling;(d) positive displacement machines; and(e) test procedures to be used for design, production or field testing.
