Meaning and Purpose
3.1 This guide indicates recommended test procedures for maintaining acceptable paint performance in electrophoresis tanks. Several key parameters need to be determined throughout the bath operation. These parameters need to be adjusted when deviations from the standard occur.

3.2 The test method for the electrophoresis tank is unique because the non-volatile content of the water-based samples ranges from 8% to 25%. The presence of continuous agitation is required when sampling and measuring certain parameters.

Scope of
1.1 This guide covers the selection of test methods used to determine important parameters affecting the performance of electrophoretic paints.

1.2 The test methods involved are D4370, D4399, D4584 and D5145.

1.3 This international Standard has been developed in accordance with the internationally recognized standardization principles established in the Decision on Principles for the Development of International Standards, Guidelines and Recommendations issued by the Committee on Technical Barriers to Trade of the World Trade Organization.
