    nice and concise explanation

    I believe the WAFAC is only in use by NIST, not ADCL’s… The ADCL’s use secondary standard well chambers, traceable to NIST via seed calibrated at NIST using WAFAC. A detailed reading of Appendix B to TG43U1(2004) supports my conclusion.

      I agree with what you are saying. Also, to be NIST traceable for HDR, isn’t a spherical chamber used by the ADCL? or am I missing something

    Thank you for the corrections regarding the use of WAFACs! I have updated the solution.
