What 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 performance of louvres subjected to simulated rain.

BS EN 13030 specifies a method for measuring the water rejection performance of louvres subject to simulated rain and wind pressures, both with and without air flow through the louvre under test.

Note: BS EN 13030 is not intended for the evaluation of weather performance of pressure relief dampers.

Who is BS EN 13030 - Performance testing of louvres in ventilation terminals for?  

BS EN 13030 on performance testing of louvres in ventilation terminals form is relevant to: 

Manufacturers of ventilation terminals
Louvre manufacturers 
Product designers
Quality control and testing personnel 
Building authorities/owners/management
Local bodies

Why should you use BS EN 13030 - Performance testing of louvres in ventilation terminals?  

Weather louvres are designed to restrict the passage of water during rainfall while allowing the passage of air into or from an air distribution system or part of a building. They are used in a wide range of applications, where there may be differences in wind speed and direction, levels of local turbulence, rate and droplet size, distribution of rainfall and surface water flow from the surrounding structure. It is impractical to consider a standard test procedure simulating the whole range of likely conditions, but BS EN 13030 provides for heavy rainfall directed onto the louvre surface, with simulated wind pressures. This provides a common basis on which to compare the water rejection performance of weather louvres of different designs.

In order to ensure the performance of louvres, BS EN 13030 provides test methods. The purpose of tests incorporated in BS EN 13030 are as follows:

Weather tests- to establish the weather louvre effectiveness when subjected to wind pressure at various air flow rates
Discharge and Entry loss coefficient/Pressure requirements- to establish the air pressure loss through the weather louvre at various air flow rates and by calculating the Discharge and Entry Loss Coefficient

Thus, if you are a manufacturer of louvres for ventilation terminals, compliance with BS EN 13030 performance testing can be beneficial for quality control purposes to ensure your products are reliable and effective at the point of use.
