Used in ASTM Method D 3450, Test for Washability Properties
This is a finely ground dispersion of high jet carbon black in a blend of mineral oil and odorless mineral spirits. It is specified in ASTM D3450 to meet the laboratory requirement for a reproducible composition of matter, representative in a general way of soilants encountered in the field.
Both media have perfect package stability and are manufactured and control tested to assure batch-to-batch uniformity. Their usefulness extends not only to ASTM tests, but to any soil and stain removal test procedure. Supplied in 4 fl.oz. (118 mL) cans or jars.
