ASTM D257 Surface Volume Resistivity Testing

ASTM D257 covers measurement of surface resistivity and volume resistivity for plastics, coatings, and insulating materials. Understanding resistivity is crucial for antistatic performance, insulation reliability, and electrostatic discharge control. Infinita Lab uses precise electrometers and guarded electrodes to determine resistivity under controlled environmental conditions. We deliver clear, actionable reports showing resistivity values, test setup, and environmental parameters. Rely on Infinita Lab’s expertise to verify material electrical properties for manufacturing, safety compliance, and electronic applications.
