Cleanliness Analysis, Measurement Process, The patented Metal-Nonmetal recognition, Evaluation Samples, Oil Cleanliness Advanced technical products in automotive, aircraft and medical industries require clean components. Industrials standards like VDA Vol. 19 and ISO 16232 are the frameworks for cleanliness analysis. • What are the reasons for the increasing cleanliness testing demand? • Smaller tolerances make systems more sensitive to dirt • Cleanliness and system life times are correlated • Large residue particles (killer particles) may cause function loss • Exhaust is correlated with smooth (unscratched) surfaces • Noise is correlated with smooth (unscratched) surfaces • Recycle laws demand lead free products (less dirt tolerant) Extract the particles (the dirt) from the part or component by use of fluid Filter the fluid by pouring it through a filtermembrane Remove the filter from the filteration equipment. (Usually it will be dried in an oven). Cleanliness is measured by analyzing filter membranes which contain the residual dirt of washed components. What are the largest particles found ? What is the size distribution of particles ? What kind of particles are on the filter ? Metallic, Nonmetallic, Fibers. Microscopic analysis can answer the questions about sizes, metallic and nonmetallic type as well as fiber type. Automated, microscopic particle counting started around the year 2000 and is the major method for filter analysis. Nowadays (2019) thousands of laboratories are testing cleanliness this way. The JOMESA HFD cleanliness analysis system is the unquestioned market leader in microscopic filter analysis.
