Ventilation for buildings. Terminals. Performance testing of louvres subjected to simulated rainWhat is BS EN 13030 Performance testing of louvres in ventilation terminals about? A ventilating system supplies fresh air inside a room and also removes the used air to outside. The factors that govern the operation of the ventilating system are the temperature of the air, humidity, and purity of the air. BS EN 13030 is a European Standard that discusses ventilation for buildings using air terminals. The main objective of BS EN 13030 is to test the
