Measurement of Electrical Properties of Elastomers

The following electrical measurements are performed at the O-Ring-Test-Laboratory Richter GmbH:

  • Measurement of volume resistance and volume resistivity on sheet material (minimum size 80×80×2)
  • Measurement of surface resistance and surface resistivity on sheet material
  • Measurement of resistance on test sheets and finished parts, also in combination with immersion tests
  • Measurement of resistance on test sheets and finished parts under deformation/stress
  • Measurement of potential difference according to DBL5527 analogous to DIN 50918
  • Measurement of conductivity (insulation effect) according to DBL5527

Measuring instruments:

  • Milli-TO3 (Fischer Elektronik)
    • Resistance measuring range: 1×10-5 Ohm to 1,6×1015 Ohm, Metering voltage: 1-500V adjustable
  • Measuring probe FE50 (Fischer Elektronik)
  • Benning IT 101
    • Resistance measuring range 0-20GOhm
    • Test voltage 50/100/250/500/1000V
    • Measuring range voltage 0-600V

Standards:

DIN ISO IEC 60093, ASTM D4496, ASTM D257, DBL 5527, SAEJ1645

Hardness and density are fast and easily ascertained. Therefore, they are ideal for incoming goods inspection and testing.

The hardness test is probably the most applied and most common test method in the elastomer industry.
