4.1 The nonvolatile content and pigment content are measures of total solids and inorganic pigment solids, respectively, in electrocoat paints. In addition to production quality control, these properties are important in maintaining electrocoat baths in the optimum range.

4.2 Other test methods for determining nonvolatile content of paint and paint related materials are described in Guide D2832.

1.1 These test methods cover the characterization of electrocoat baths through the determination of nonvolatile content of inorganic pigment content.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 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.

1.4 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.
