Describes the calibration of field pyrheliometers using reference pyrheliometers and sets out the calibration hierarchy for the transfer of the calibration.

This International Standard describes the calibration of field pyrheliometers using reference pyrheliometers and sets out the calibration procedures and the calibration hierarchy for the transfer of the calibration.

This International Standard is mainly intended for use by calibration services and test laboratories to enable a uniform quality of accurate calibration factors to be achieved.
