The BIA is a government agency, which directs the setting up of rules and standards in order
to meet certain safety and quality standards in Europe. One of those is the AH1/487 ABS 2
test procedure for different filtering media used in dust collection equipment. The test is
carried out on small media samples, and the test dust is standardized. The approach velocity
on the media during the test is standardized on 11 F.P.M. (11:1 A/C ratio). During the test, a
quantity of approximately 0.078 Gr/cu.ft. of dust is fed to the media, and the penetration is
measured. In this way a certain penetration is determined which rates the media in
preclassified levels, the so called U.S.G. or C. The U media's are the lowest efficiency
medias; the C medias are the highest efficiencies. The maximum allowable penetration
degrees for the different classifications are:
