ASTM D 4496 : 2013

1.1This test method covers the determination of electrical resistance and electrical resistivity of materials that are generally categorized as moderately conductive and are neither good electrical insulators nor good conductors.

1.2This test method applies to the materials that exhibit volume resistivity in the range of 10⁰ to 10⁷ Ω-cm or surface resistivity in the range of 10³ to 10⁷ Ω (per square).

1.3This test method is designed for measurements at standard conditions of 23°C and 50 % relative humidity, but its principles of operation can be applied to specimens measured at lower or higher temperatures and relative humidities.

1.4This 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 and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in 8.3.
