摘要： A procedure for testing the efficiency of filtration media is disclosed. The procedure employs uniform microspheres in a latex which are suspended in an airstream and directed through the medium to be tested. The liquid in the airstream is removed from the airstream after passing through the medium, and a portion of the airstream is directed to a particle counter to count the particles in the airstream. By comparing the particles counted with and without the medium in the airstream, the efficiency of the medium can be determined.
摘要翻译： 公开了一种用于测试过滤介质效率的方法。 该方法在胶乳中使用均匀的微球，其悬浮在气流中并引导通过要测试的介质。 气流中的液体在通过介质之后从空气流中除去，并且一部分气流被引导到颗粒计数器以计数气流中的颗粒。 通过比较在气流中与无介质计数的颗粒，可以确定介质的效率。
