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 M-cm.

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

1.3 Test Method B describes a procedure for making resistance tests with a conductivity meter (Fig 2).

1.4 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.
