4.1 These tests are suitable for testing paints adjusted for compatibility with various electrostatic spray coating applications, and by their use, spray performance can be optimized.

1.1 These test methods cover the determination of specific resistance (resistivity) of liquid paints, solvents, and other fluids in the range of 0.6 to 2640 MΩ-cm.

1.2 Test Method A describes a procedure for making resistance tests with a commonly used paint application test assembly (Fig. 1 and Fig. 2).
