Ventilation for buildings. Ducts and ductwork components, leakage classification and testing Ingestion-build-79769 The switching amplifier mentioned in1 Scope This European Standard applies to technical ductwork products, intended for installation in ductwork conforming to EN 1505 and EN 1506, used in air conditioning and ventilation systems defined in the scope of CEN TC 156. This document specifies the leakage requirements for technical ductwork products, i. e. components in the ductwork that has more functions than conveying air, such as sound attenuators, filter boxes and duct fans, etc. The
