Rationale

Traditionally the measurement of solar radiation served the meteorological community. The requirements for the measurement accuracy were low and economic consequences of errors were non-existent. For example, the emerging markets of weathering and durability and solar renewable energy require accurate measurements and measurement results are put to commercial use. These markets would strongly benefit from standardization of uncertainty evaluation, calibration, measurement methods and measurement instruments, including test methods to determine instrument characteristics. This proposed standard focusses on standardization of measurement instruments. An accepted way to standardize measurement instruments is by classification. A division in classes allows users with different target measurement uncertainties to easily make a choice between instruments.
