BS 7440:1991

This standard BS 7440:1991 Method for calibrating field pyrheliometers by comparison to a reference pyrheliometer is classified in these ICS categories:

• 07.060 Geology. Meteorology. Hydrology

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.
