BS EN 16211:2015 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.Cross References:EN 12792EN 14277ISO 10241-1ISO 690ISO/IEC Guide 98-3:2008GUM:1995ISO 3966EN ISO 5167-1ISO 5167-1EN ISO 5167-2ISO 5167-2EN ISO 5167-3ISO 5167-3EN ISO 5167-4ISO 5167-4ISO 5221ISO 4053-1JCGM. 200ISO/IEC Guide 98-3EN 12599All current amendments available at time of purchase are included with the purchase of this document.
