DESCRIPTION
23/30467030 DC
This standard 23/30467030 DC BS EN 16211. Ventilation for buildings. Measurement of air flow rates on site. Methods is classified in these ICS categories:
17.120.10 Flow in closed conduits
91.140.30 Ventilation and air-conditioning systems
17.120.10 Flow in closed conduits
91.140.30 Ventilation and air-conditioning systems
This document specifies methods for the measurement of air flow rates on site. It provides a description of the air flow rate measurement methods and how measurements are performed within the margins of stipulated method uncertainties. It gives the necessary measurement conditions (e.g. length of straight duct, uniform velocity profile) to achieve the stipulated measurement uncertainties. The methods for measuring the air flow rate inside ducts do not apply to: - ducts that are not circular or rectangular (e.g. oblong ducts); - flexible ducts.
