This standard BS EN 13182:2002 Ventilation for buildings. Instrumentation requirements for air velocity measurements in ventilated spaces is classified in these ICS categories:
23.120 Ventilators. Fans. Air-conditioners
91.140.30 Ventilation and air-conditioning systems
17.080 Measurement of time, velocity, acceleration, angular velocity
This standard specifies the main characteristics of air velocity measuring devices. This includes requirements for thermal velocity probes, recalibration and the signal processing of measurements in a ventilated space, including those in the air jet and in the occupied zone. Other types of velocity measuring devices should fulfil the performance parameters stated but appropriate calibration techniques should not necessarily be used which are described in this standard
