    • A method and apparatus for testing the effectiveness of a building air barrier, or part thereof, whereby an identification of any air leakage therethrough is provided. A soap solution (or other solution having a similar bubbling characteristic) is applied to a selected air barrier test area. An open-ended flask is positioned over the test area and a centrifugal (or standard) fan is activated at the head of the flask to create an air pressure differential across the air barrier. In the presence of the air pressure differential the soap solution will bubble if there is an air leakage in the air barrier within the test area and, therefore, the existence or non-existence of bubbles in this area identifies whether or not there is an air leakage (i.e. break) in the air barrier in that area.
    • 一种用于测试建筑物空气屏障或其一部分的有效性的方法和装置,由此提供了通过其识别任何空气泄漏。 将肥皂溶液(或具有类似起泡特性的其它溶液)施加到所选择的空气阻挡试验区域。 将开口的烧瓶放置在测试区域的上方,并且在烧瓶的头部处启动离心(或标准)风扇,以在空气屏障上产生气压差。 在存在空气压差的情况下,如果在测试区域内的空气屏障中存在空气泄漏,则肥皂溶液将会起泡,因此在该区域中存在或不存在气泡来识别是否存在空气 在该地区的空气屏障中泄漏(即断裂)。
