本欧洲标准规定了现场空气流量测量的简化方法。它提供了空气流动方法的描述，以及如何在规定的方法不确定性的范围内进行测量。 一种测量方法是在管道的横截面上进行点速度测量以获得空气流。这种简化的方法是ISO 3966和EN 12599中描述的方法的替代方法。该欧洲标准要求满足简化方法规定的测量不确定度的某些测量条件（直管长度和均匀速度曲线）

This European Standard specifies simplified methods for the measurement of air flows on site. It provides a description of the air flow methods and how measurements are performed within the margins of stipulated method uncertainties. One measurement method is to take point velocity measurements across a cross-section of a duct to obtain the air flow. This simplified method is an alternative to the method described in ISO 3966 and EN 12599. This European Standard requests certain measurement conditions (length of straight duct and uniform velocity profile) to be met to achieve the stipulated measurement uncertainties for the simplified method.
