This Standard specifies a set of technical requirements and test
methods for solar collectors and covers component materials,
materials performance, operating performance, and marking
This Standard applies to solar collectors used for converting
solar radiation into thermal energy. It covers only collectors with
an aperture area of not less than 0.5 m2. Typical applications for
the collectors covered by this Standard include their use in
systems for space heating or cooling and the heating of water.
This Standard covers collectors capable of being tested as
independent units with forced circulation of the heat transfer
fluid. It also applies to installation dependent collectors such as
those designed for site assembly, surface mounting or rack
mounting. Scaled down versions of large collectors may be tested
provided that appropriate test parameters are retested and that the
test specimen is constructed to ensure that the test results shall
as far as possible be applicable to the installed unit.
This Standard is intended to apply to the following types of
(a) glazed and unglazed flat plate collectors;
(b) vacuum envelope collectors;
(c) concentrating collectors; and
(d) boiling/condensing collectors.
This Standard does not apply to any collectors designed for
fluid temperatures above 300" C, or to boiling collectors which
require a separate condensing heat exchanger.
This Standard does not cover the installation or mounting of
solar collectors; neither does it cover the tracking mechanism of
sun following collector systems nor any other part of a solar
Compliance of a collector with this Standard may not completely
define its suitability for an intended application. Specifically,
(a) does not define minimum values for the solar collector
(b) does not define thermal performance testing for collectors
to be used in passive systems with convective circulation of the
heat transfer medium. Testing of the collector for thermal
performance by appropriate procedures not included in this Standard
should be considered by the user for such applications;
(c) defines only the thermal performance testing procedures
applying to a single isolated collector. This Standard does not
address the issue of collector array performance.
