ASTM C657-19<\/h3>\n

Active Standard: Standard Test Method for D-C Volume Resistivity of Glass<\/h4>\n
\n

ASTM C657<\/h4>\n

Scope<\/strong><\/p>\n

\n

1.1<\/span> This test method covers the determination of the dc volume resistivity of a smooth, preferably polished, glass by measuring the resistance to passage of a small amount of direct 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.<\/p>\n<\/p><\/div>\n

\n

1.2<\/span> This test method is intended for the determination of resistivities less than 1016<\/sup>\u2009\u03a9\u00b7cm in the temperature range from 25\u2009\u00b0C to the annealing point of the glass.<\/p>\n<\/p><\/div>\n

\n

1.3<\/span> 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. For specific hazard statements, see Section 5<\/span>.<\/span><\/i><\/p>\n<\/p><\/div>\n

\n

1.4<\/span> 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.<\/i><\/p>\n<\/p><\/div>\n
