Pulps. Estimation of dirt and shives - Instrumental inspection by reflected light using equivalent black area (EBA) method Ingestion-build-183511 BS EN 4626-201:2009 Aerospace series1 Scope This part of ISO 5350 specifies a method using instrumental inspection by reflected light for the estimation of visible dirt and shives in pulp manufactured in sheets, in terms of Equivalent Black Area (EBA) of dirt specks within the physical area range of 0,02 mm2 to 3,0 mm2. Using the algorithm prescribed in this part of ISO 5350, the maximum dirt size is limited to 3,0 mm2. Extension to other speck sizes (for example, those greater than 3,0
