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
