1 Scope

This standard specifies the calibration conditions for the UV radiation table, the calibration method, and the uncertainty of the calibration results. This standard applies to the solar broadband UV radiation table sensitivity calibration.

2 terms and definitions

The following terms and definitions apply to this document. 2.1 Ultraviolet radiation table Broadband ultraviolet radiation table broadbandultra ultravioletradiometer Bandwidth greater than tens of nanometers, measuring ground ultraviolet ultraviolet radiation (UV) instruments. Note. According to the measurement of the spectral range can be divided into three categories. measuring UV-A (315nm ~ 400nm), UV-B (280nm ~ 315nm) or UV-AB (280nm ~ 400nm) broadband ultraviolet radiation table.
