Measuring inductance or capacitance; Measuring quality factor, e.g. by using the resonance method; Measuring loss factor; Measuring dielectric constants

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Arrangements for measuring resistance, reactance, impedance, or electric characteristics derived therefrom > Measuring real or complex resistance, reactance, impedance, or other two-pole characteristics derived therefrom, e.g. time constant > Measuring inductance or capacitance; Measuring quality factor, e.g. by using the resonance method; Measuring loss factor; Measuring dielectric constants

CPC:

Arrangements for measuring resistance, reactance, impedance, or electric characteristics derived therefrom > Measuring real or complex resistance, reactance, impedance, or other two-pole characteristics derived therefrom, e.g. time constant (by measuring phase angle only G01R25/00) > Measuring inductance or capacitance; Measuring quality factor, e.g. by using the resonance method; Measuring loss factor; Measuring dielectric constants

Of 4 combined children, 0 exist in both systems.

4 codes are CPC-only extensions.
