An air tightness test is defined as a procedure to determine the air tightness of a given pipeline at air tight joints and U traps. In order to maintain the pressure in the pipeline, a certain amount of air has to escape. Thus, an air tightness test also determines the percentage of lost air over a certain time period.
Air tightness testing equipment can be used in several ways. The standard air tightness or blower door test requires that a single fan get set up in a doorway into an expandable frame that fills the doorway. Onto the frame is mounted a canvas type membrane or cloth with a hole in it. The testing fan is then fit into the frame/cover and is ...
