This part of IEC 60721 presents a broad division into types of solar radiation areas. It is intended to be used as part of the background material when selecting appropriate severities of solar radiation for product applications. All types of geographical areas are covered, except areas with altitudes above 5 000 m. This document also serves to define limiting severities of solar radiation to which products are liable to be exposed during transportation, storage and use.
