1. Scope

1.1 This standard (Part 5) covers the determination of thermal performance of tracking concentrating solar collectors and non-tracking non-imaging concentrator (NIC).

1.2 This test method applies to one or two-axis tracking reûecting concentrating collectors and non-imaging concentrator (NIC) in which the ûuid enters the collector through a single inlet and leaves the collector through a single outlet, multiple collectors in series having single inlet and outlet may also be used.

1.3 This test method is for outdoor testing only, under clear sky, quasi-steady state conditions.

1.4 This test method covers alignment, preconditioning and calculation of efficiency and analysis of data generated to give efficiency equation.

1.5 The rating of the collector is beyond the scope of this standard.

1.6 Specification of component, their sampling and analysis methods are covered in the other parts of this standard for different types of collector.

1.7 This test method does not provide a means of determining the durability or the reliability of any collector or component.

1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
