Scope

This document gives guidelines to correct the measured air flow rate when measuring conditions are different from standard conditions.
It applies to a power-law formula giving the air flow rate as a function of a pressure difference with an air flow rate coefficient, C, varying with temperature and pressure.
This document applies to:
- passive elements of air distribution systems with a cross-section area that does not depend on pressure;
- volume flow rate (and not mass flow rate).
This document is applicable to (but not limited to):
- EN 1507, Ventilation for buildings - Sheet metal air ducts with rectangular section - Requirements for strength and leakage;
- EN 1751, Ventilation for buildings - Air terminal devices - Aerodynamic testing of damper and valves;
- EN 12237, Ventilation for buildings - Ductwork - Strength and leakage of circular sheet metal ducts;
- EN 13141 1, Ventilation for buildings - Performance testing of components/products for residential ventilation - Part 1: Externally and internally mounted air transfer devices;
- EN 13141 2, Ventilation for buildings - Performance testing of components/products for residential ventilation - Part 2: Exhaust and supply air terminal devices;
- EN 13141 9, Ventilation for buildings - Performance testing of components/products for residential ventilation - Part 9: externally mounted humidity controlled air transfer device;
- EN 13141 10, Ventilation for buildings - Performance testing of components/products for residential ventilation - Part 10: humidity controlled extract air terminal device;
- EN 15727, Ventilation for buildings - Ducts and ductwork components, leakage classification and testing.
This document does not apply to:
- fans;
- air terminal devices with automatically controlled openings (variable openings).
