Abstract
Dow Home and Personal Care has developed a protocol using a custom imaging station and software suite to standardize data collection and automated analysis in automatic dishwashing. Previously, a panel rating based on ASTM D3556-14 was used to provide a score for filming and spotting on glassware. Progress has been made toward a standardized and semi-automated method utilizing a combination of a custom imaging station built in house, image analysis techniques, and a statistical model. The statistical model was built using a series of panel ratings from an array of glasses, giving computed ratings which agree closely with experimental scores assigned by human raters.Keywords
