5.1x00a0;This test method is intended to provide test data essential to the prediction of the thermal performance of a collector in a specific system application in a specific location. In addition to the collector test data, such prediction requires validated collector and system performance simulation models that are not provided by this test method. The results of this test method therefore do not by themselves constitute a rating of the collector under test. Furthermore, it is not the intent of this test method to determine collector efficiency for comparison purposes since efficiency should be determined for particular applications.

5.2x00a0;This test method relates collector thermal performance to the direct solar irradiance as measured with a pyrheliometer with an angular field of view between 5 and 6x00b0;. The preponderance of existing solar radiation data was collected with instruments of this type, and therefore is directly applicable to prediction of collector and system performance.

5.3x00a0;This test method provides experimental procedures and calculation procedures to determine the following clear sky, quasi-steady state values for the solar collector:

5.3.1x00a0;Response time,

5.3.2x00a0;Incident angle modifiers,

5.3.3x00a0;Near-normal incidence angular range, and

5.3.4x00a0;Rate of heat gain at near-normal incidence angles.

Note 4x2014;Not all of these values are determined for all collectors. Table 1 outlines the tests required for each collector type and tracking arrangement.
