Standard Guide for Deposition on Glassware During Mechanical Dishwashing
SIGNIFICANCE AND USE
3.1 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 guide 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 and commercial 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.3 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.

it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version

tumbler at intervals throughout the test (see Note 5 in Section 66.7.3). Ten tumblers simplify scoring.
4.2.1 Before each use, even if new, the glass tumblers may be cleaned in a machine, first in a 1 % solution of citric acid and then
with a household automatic dishwashing detergent at the manufacturer’s recommended use level, each in a normal wash cycle. Use

rinsed. Any other procedure (such as hand washing and polishing) which yields tumblers that are spot- and film-free may be used.

4.3.1 Suggested tableware is as follows, Dinner plates, 10-in.10 in. diameter, Salad plates, 7-in.7 in. diameter, Cereal bowls,
