Ventilation for buildings. Terminals. Performance testing of louvres. Performance testing of louvres subject to simulated sand Ingestion-build-133579 This is one reason whyWhat is BS EN 13181 Performance testing of louvres subject to simulated sand about? Indoor air is kept fresh and healthy with proper ventilation. A louvre is a ventilation product that allows air to pass through it whilst keeping out unwanted elements such as water, dirt and debris. BS EN 13181 is a European Standard that discusses terminals for building ventilation. BS EN 13181 specifies a method for measuring the sand rejection efficiency of sand
