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).
