3.1
specific resistance
volume resistance of fibers in a certain volume, calculated based on fiber density
4 Principle
According to the equation of volume resistance, , the resistance of fibers with a certain density in a certain geometry is measured, and then it is converted into specific resistance according to the packing density of fibers.
5 Instruments and tools
5.1 Fiber specific resistance meter
The requirements for fiber specific resistance meter are as follows:
a) Measurement range of instrument: 102Ω~1014Ω.
