ASTM D8549-25

1.1 This is a guide for evaluating stain removal performance of home dish products or home hand dishwashing conditions. It provides guidance for the selection, preparation, application, and examination of various types of stains on test tiles that are subjected to controlled but practical stain removal.

1.2 There is no single combination of stain and tile material that will predict the overall performance of a product or treatment method. A single test, even with a variety of stains, can only predict how products or treatment methods compare under the conditions chosen for evaluations. A series of assessments is necessary to evaluate the many aspects of stain removal performance and to simulate consumer experience more closely.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
