Basic Information
Scope
Main technical content: This standard specifies the principle of measuring the volume resistivity of carbon fiber filaments and single filaments by the four-probe method, the measurement instruments, sample requirements, test conditions, measurement procedures, calculation of results, and test reports, etc. This standard is applicable to the measurement of volume resistivity of various types of carbon fibers ranging from 1K to 24K, and can also be extended to the measurement of volume resistivity of conductive wires. Fibers with a modulus greater than 600GPa are not suitable for the measurement of volume resistivity of composite filaments, and fibers with a resistivity greater than 15 μΩ·m are not suitable for the measurement of single filaments.
