scope:

This part of ISO 9806 establishes methods for determining the thermal performance of glazed liquid heating solar collectors. These tests are intended for use as part of the sequence of tests specified in ISO 9806-2.

This part of ISO 9806 provides test methods and calculation procedures for determining the steady-state and quasi-steady-state thermal performance of solar collectors. It contains methods for conducting tests outdoors under natural solar irradiance and for conduction tests indoors under simulated solar irradiance.

This part of ISO 9806 is not applicable to those collectors in which the thermal storage unit is an integral part of the collect to such an extent that the collection process cannot be separated for the purpose of making measurements of these tow processes.

This part of ISO 9806 is not applicable to unglazed solar collectors nor is it applicable to tracking concentrating solar collectors.
