Appendix GNew ISO Medium Test Dust and its effect onISO Contamination Control StandardsWhen General Motors gave advance warning to the International StandardsOrganization (ISO) that it was intending to stop the production of AC FineTest Dust (ACFTD), work commenced immediately on finding an improvedreplacement dust. ACFTD was used extensively within the fluid power andautomotive industries for calibrating Automatic Particle Counters (APCs)and for the testing of components.APCs are used for testing oil filters, and also for contaminant sensitivity testingof hydraulic components. For 25 years, APCs have been the main stay inthe measurement of solid particles in hydraulic fluids. The growth in demandfor measuring fluid cleanliness in a variety of industrial processes, includingfluid power, has resulted in APCs moving from the laboratory environmentout into the factory. In fact, they are now a critical part of many productionprocesses. It is therefore essential that the data they provide is both accurateand consistent.CalibrationACFTD has been used as an artificial contaminant since the 1960s and itsoriginal particle size distribution was determined using an optical microscope.This particle size distribution subsequently formed the basis of ISO4402, the method for calibrating APCs. Due to the limitations of that methodof measurement, the particle size distribution was questioned below about5µm. It was also not traceable to any national standard of measurement - acritical requirement for today’s quality management systems.There was also an absence of formal controls over the distribution of thetest dust, and batch-to-batch variability was much greater than is acceptablenowadays.New ISO Medium Test Dust and its effect on ISO . . . 73
