1 Scope
This document defines basic terms relating to the work of ISO/TC 180. The committee
covers standardization in the field of the measurement of solar radiation and solar energy utilization in space and water heating, cooling, industrial process heating and air
conditioning. Consequently, the vocabulary within this document is focussed on definitions
relating to those measurement and utilisation technologies.
Since the 1999 version of this document there has been considerable development in
solar photovoltaic technologies and high temperature solar thermal technologies that
use heat to produce electricity or to provide high temperatures for processes that
require elevated temperatures. This standard has some definitions that are useful
also for those technologies; however, there are other documents that cover vocabulary
for these technologies in more detail.
