ASTM C657 : 24

Standard Test Method for Volume Resistivity of Glass

Standard Details

1.1 This test method covers the determination of the volume resistivity (as defined in Terminology D1711) of a smooth, preferably polished, glass by measuring the resistance to passage of a small amount of current through the glass at a voltage high enough to assure adequate sensitivity. This current must be measured under steady-state conditions that is neither a charging current nor a space-charge, buildup polarization current.

1.2 This test method is intended for the determination of resistivities less than 10¹⁶ Ω·cm in the temperature range from 25 °C to the annealing point of the glass.

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.
