Popis:	The filter efficiency of materials to be used in respiratory protective devices is commonly measured by using a solid NaCl particle challenge and a flame ionization detector. The Moore's BS 4400 Bench Rig is an example of such equipment. Recently, TSI, Inc. introduced their Model 8110. This system also produces a NaCl particle challenge. It uses a laser diode detector. The filter efficiencies of two different filter materials were determined in a comparative study utilizing several Moore's and TSI systems. The results indicate that the two test systems are relatable and that the between-machine consistency of the Model 8110 is better than the Moore's system.
