We are active participants in many international intercomparisons of thermal transfer standards at all frequencies and voltages in our parameter space, and in comparisons of dc voltage.
The most recent comparisons are listed below:
- CCEM-K6a: Comparison of thermal converters at the limits of uncertainty (complete)
- CCEM-K6b: Comparison of thermal converters at high voltage (discontinued)
- CCEM-K6c: Comparison of thermal converters at high frequencies (complete)
- CCEM-K9: Comparison of thermal converters at high voltage (replication of CCEM-K6b)
- CCEM-K11: Comparison of thermal transfer standards at millivolt levels (complete)
- CCEM-K12: Comparison of thermal transfer shunts (Draft A)
- SIM intercomparisons (replication of CCEM-K6a, CCEM-K9, CCEM-K11, and CCEM-K12, in progress)
