Sunday , January , 21 2018


The Helmke drum test is a non-destructive particle-counting tumble test designed to measure particles released at 0.3 microns or greater over a tumbling garment or wipe, the Helmke drum test is widely used by cleanroom laundries, or garment processors, to determine the efficiency of the cleaning process. A laser automatic particle counter is used to sample the air within the drum to determine the average particle release rate in particles per minute for particles equal to or greater than 0.3 µm. However, the Helmke Drum Test does not discriminate between particles and fibers and release of contamination from the inside and outside of the garment, unless all garment closures are sealed during the test — an important requirement when testing laminated barrier garments.
