This standard describes a method for determining conductivity in an Electrophoresis bath. Conductivity reflects the Ion concentration in an Electrophoresis bath and affects the application and performance of the Coating. This test is suitable for research, production and quality control of Electrophoresis processes. The standard covers procedures for the measurement of conductivity of samples in Electrophoresis tanks or ultrafiltrates using commercially available equipment and is suitable for applications in real production environments. Not all safety issues are included in the standard. Users need to establish appropriate safety and health practices and comply with relevant regulations.
