導入
The period of natural weathering, accelerated natural weathering, artificially accelerated weathering, or artificially accelerated radiation exposure is defined only in terms of time, ignoring the influence of changes in spectral irradiance of the source and the moisture and/or temperature difference between different exposure tests. Defining the period of natural weathering exposure in terms of total exposure to solar radiation has been shown to be helpful in comparing the outcomes of these exposures at different times in the same location. しかし, it is also important to monitor solar UV radiation exposure from natural weathering exposure and UV radiation exposure from artificially accelerated weathering or artificially accelerated irradiation exposure.

Two methods of measuring UV radiation are commonly used. The first is the use of physical criteria, つまり. exposure to a reference material that shows a property change proportional to the dose of incident ultraviolet radiation. The preferred option is to use a radiometer that responds to ultraviolet light. This document describes this method. It recommends the important characteristics of the instruments used and provides guidance for the selection and use of these radiometers.

1 範囲
This document specifies an instrumental method for measuring irradiance on a flat surface. This includes not only natural solar radiation, but also enhanced natural solar radiation and radiation produced by laboratory light sources.

To measure natural weathering and solar radiation that accelerates natural weathering, instrumental techniques include continuous measurements of the sun, solar ultraviolet and spectral solar (ultraviolet) irradiance, as well as the accumulation or integration of instantaneous data to provide radiation exposure.

To measure radiation in artificially accelerated weathering or artificially accelerated irradiation, instrumental techniques include the continuous measurement of total or defined bands of ultraviolet radiation, visible spectral irradiance and/or ultraviolet spectral irradiance, and the accumulation or integration of instantaneous data to provide radiation exposure.
