3.1 The guide is suitable for ranking of hand dishwashing products, using food soil or combination of soils with objective color measurement ranking of performance.

3.2 The relative wash performance ranking of hand dishwashing detergent products will vary depending on the type of food soils and/or standardized ready to use test materials used in the test. Therefore, a selection of the standard food soil or ready to use test materials to be used in a test shall be made by agreement between the interested parties based on experience.

3.3 This guide provides guidelines for measuring the cleaning performance of light-duty hand dishwashing detergents in the presence of artificially applied test soils and/or standardized Ready to Use (RTU) test materials. It is intended as a laboratory screening test to aid in the formulation of products, for quality control and as a basis between the formulator and supplier in standardizing specific products’ cleaning performance.

3.4 The evaluations generated by this guide includes flexibility of soil and substrate to allow the enduser to decide which combination is best suited to meet product. It is also suited for both enzymatic and nonenzymatic type of hand dish products. This procedural latitude may result in a reduced level of interlaboratory precision, and such comparison of results must be evaluated with caution.

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.
