IEST – RP – CC003.4 “The Helmke Drum test method is used to quantify particles dislodged from garments through the application of mechanical energy under dry conditions as a means of simulating particle shedding from the surface of the garment during use.”

Berkshire also uses the Helmke Drum method to quantify the number of particles that could potentially be emitted from BCR® cleanroom paper versus standard copy paper. We place sheets of paper in the rotating drum and particles generated by the tumbling paper are counted by an air-borne particle counter.

Na+ 100ppm Vs 1500ppm!
