This NORDTEST method is to be used for monitoring the natural and forced ventilation rate in different parts of a building or an apartment.
2. FIELD OF APPLICATION
This method can be used in all common types of buildings. The application is limited by practical difficulties which arise if at the same time the volume is large and the ventilation rate is high. Difficulties in interpreting the result can arise in rooms with large air flows from adjoining rooms. That is air flows, which in comparison with air flows directly from the outside, are large.
