CCEM-K4.2017
Information
Metrology area, branch   Electricity and Magnetism, Capacitance
Description   Comparison of 10 pF capacitance standards
Optional: comparison of 100 pF capacitance standards
Time of measurement   2017
Status   In progress
Reference(s)   CCEM-K4.2017 Registration and progress form
CCEM-K4.2017 Technical Protocol, 36 pp.
Measurand   Capacitance at 10 pF (optional capacitance at 100 pF)
Parameter(s)   Frequency at 1592 Hz (otptional frequency at 1233 Hz) / Voltage 100 V (10 V for optional 100 pF capacitance value)
Transfer device(s)   The scheme adopted is that of a collapsing star consisting in carrying out simultaneously a large number of bilateral comparisons piloted by the BIPM. The capacitance standards of each of the participant are compared using the BIPM capacitance standards as the common references.
Comparison type   Key comparison
Consultative Committee  CCEM (Consultative Committee for Electricity and Magnetism)
Conducted by   BIPM (Bureau International des Poids et Mesures)
Comments   This comparison is a repeat of CCEM-K4
