scope:

This standard applies to technical ductwork products, intended for installation in ductwork conforming to EN 1505, EN 1506, EN 13180 and EN 13403, used in air conditioning and ventilation systems defined in the scope of CEN/TC 156. This standard specifies the leakage requirements for technical ductwork products, i.e. components in the ductwork that has more functions than conveying air. Dampers according to EN 1751 are not included in this standard. This standard is a parallel standard to EN 12237, EN 1507, EN 13180 and EN 1751, based on the same leakage classification.
