Ventilation for buildings. Ductwork. Strength and leakage of circular sheet metal ducts Ingestion-build-109673 BS 7317-5 describes a methodWhat is BS EN 12237 Ductwork requirements for building ventilation about? Ductwork channels are essential to the ventilation of buildings they contribute to better indoor air quality irrespective of external weather conditions through the year. BS EN 12237 specifies requirements and test methods for strength and air leakage of circular ductwork used in air conditioning and ventilation systems in buildings. BS EN 12237 is intended to establish the
