ASTM D 257 : Standard
Test Methods for DC Resistance or Conductance of Insulating
Materials
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.
These test methods are not suitable for use in measuring the electrical
resistivity/conductivity of moderately conductive materials. Use Test
Method D 4496 to evaluate such materials.<more>
