9.4 Appendix on standards for classification and calibration

Both ISO and ASTM have standards on instrument classification and methods of

calibration. The World Meteorological Organisation (WMO) has largely adopted the ISO

classification system.

Table 9.4.1 Pyranometer standardisation in ISO and ASTM.

STANDARDS ON INSTRUMENT CLASSIFICATION AND CALIBRATION

ISO STANDARD

EQUIVALENT ASTM STANDARD

ISO 9060:1990 Solar energy -- Specification

and classification of instruments for measuring

hemispherical solar and direct solar radiation

Comment: work is in progress on a new ASTM

equivalent standard

Comment: a standard “Solar energy --Methods

for testing pyranometer and pyrheliometer

characteristics” has been announced in ISO

9060 but is not yet implemented.
