ASTM D – Standard Test Methods for DC Resistance or Conductance of Insulating Materials
We have no amendments or corrections for this standard. These test methods cover direct-current procedures for the determination of dc insulation resistance, volume resistance, volume resistivity, surface resistance, and surface resistivity of electrical insulating materials, or the corresponding conductances and conductivities. Need more than one copy?
We have no document history for this standard. For sixty seconds, a voltage is applied and the resistance is measured. Surface or volume resistivity is calculated, and apparent value is given 60 seconds electrification time. Surface Resistivity is expressed in ohms per square Volume Resistivity is expressed in ohms – cm.
As the voice of the U. Surface and Volume resistivity are calculated. Volume resistivity is the resistance to leakage current through the body of an insulating material. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
dd257-99 Surface resistivity is the resistance to leakage current along the surface of an insulating material.
