It is intended to propose an intercomparison of luminous responsivity to PHORA TC as a EUROMET Bilateral Intercomparison. This intercomparison will be linked to the CIPM key comparison.
The comparison will be carried out through the calibration of two photometer heads and two filter radiometers. A description of the transfer standards is given in section 3 of the protocol.
The technical protocol has been drown up by the pilot and participating laboratories, following the main procedure applied in the CCPR-K3.b International comparison on luminous responsivity of 2001
