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 trap louvres subject to simulated sand and with inlet air flow through the louvre under test. BS EN 13181 considers a 1000 mm _ 1000 mm section of sand trap louvre, or the nearest possible blade increment, for evaluation purposes.
BS EN 13181 on Performance testing of louvres subject to simulated sand is relevant to:
The tests incorporated in BS EN 13181 are:
BS EN 13181 provides best industry guidance on conducting these sets and covers test results and calculation examples for clarity. Guidance on measurement of air flow rate, pressure and temperature is also provided.
Thus, BS EN 13181 helps you in verifying the reliability of louvres subject to simulated sand to ensure they play a positive role in the functioning of terminals and maintain the overall efficiency of ventilation systems. Compliance with the tests can ensure your products are safe, reliable and effective at the point of use.
