Cleaning Test Method DCC-03 | Rug Shampoo
DCC-03- Rug Shampoo: The original work on this test method was conducted in 1971. This method was originally devised for wool carpets. The most current amendments are designed to be used with modern, synthetic carpeting. This method was updated in 1983 to include new sources of materials, a procedure for preparing the test soil and equations for calculating cleaning effectiveness. This method was updated in 2011 to include a more accurate instrument for measuring cleaning effectiveness and an updated soil/soiling method for consistent/reproducible results. For a more detailed explanation of this method including illustrations, see DCC-03 Supplement 1 (Cleaning) and Supplement 2 (Resoil).
