(Test Method)Standard Test Method for Deposition on Glassware During Mechanical Dishwashing
Standard Test Method for Deposition on Glassware During Mechanical Dishwashing
SIGNIFICANCE AND USE
This test method is intended as a laboratory screening test to determine performance of the detergent under actual use conditions, but will not necessarily predict performance under all end-use conditions.
SCOPE
1.1 This test method covers a procedure for measuring performance of a mechanical dishwashing detergent in terms of the buildup of spots and film on glassware. It is designed to evaluate household automatic dishwasher detergents but can be used as a screening test for institutional dishwashing products.
1.2 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 and health practices and determine the applicability of regulatory limitations prior to use.
