14、visions included to supplement industry standards for quality. That document has been successfully used within the industry, and that experience led to the realization that a revision would be helpful. Thus, this version of the standard contains improvements that were realized during that implementa

15、tion. The result is a new standard that the Committee on Standards for Solar Cells and Solar Panels has developed and reached consensus that defines the best practices for space solar panel qualification.

AIAA S-112A-2013 (Revision of AIAA S-112-2005) vii Introduction This standard establishes the

23、quality requirements and provides the methods for establishing the qualification of electrical components integrated onto spacecraft solar panels. Section 7 describes specific tests necessary to ensure the quality and reliability of solar panels intended for space application. Section 8 describes sp

24、ecific solar panel characterization tests necessary to characterize the performance of solar panels intended for space application. Section 9 describes the quality requirements for panels to be qualified to this standard. Section 11 describes the reporting format for the qualification tests in Secti

25、on 7, the characterization tests in Section 8, and the quality requirements in Section 9. AIAA S-112A-2013 (Revision of AIAA S-112-2005) 1 1 Scope This document establishes qualification and quality requirements for the electrical components integrated onto spacecraft solar panels that carry single

26、crystal silicon solar cells or gallium arsenide solar cells having any number of junctions including those with metamorphic and inverted metamorphic structure. In this standard the term panel defines the assembly of electrical components to be tested. The standard also defines requirements for solar

27、 panel manufacturers quality systems and for qualification and characterization of the electrical components on solar panels. This standard fully addresses the qualification of all panel components and the panel substrate only as they affect electrical performance. Requirements for acceptance testin

28、g are not defined in this document. In accordance with the conditions stated in this section, this standard accepts qualification and characterization by similarity when approved in writing by the customer. 1.1 Qualification by Similarity If a panel to be qualified uses the same part types, material

29、s, and processes as a panel previously qualified to this standard and is exposed to environments that are encompassed by the previous qualification to this standard, this standards required tests and characterizations may be waived. If the same part types or materials are not available, equivalent p

30、art types or materials may be used if their pedigree to the same part type can be established and is satisfactory for the intended usage. If some parts, materials, and processes have changed from similarity qualification, as defined by the paragraph above, the qualification may still suffice for the

31、 unchanged parts, materials, and processes. The similarity qualification will apply only to those parts and materials that are not changed and that do not make physical contact with a changed part or material; the qualifier must show by analysis that the remaining parts and materials are not affecte

32、d to any degree by the presence of a changed part or material. The qualifier must execute the tests required by this standard on all the parts that are changed, or that are in physical contact with a changed part or that may be affected by a changed part. 1.2 Characterization by Similarity Character

33、ization is only required for parts and materials that were not characterized by similarity or that are changed or that were produced with processes that changed since the similarity characterization. 1.3 Reporting Requirements for Qualification and Characterization by Similarity Report in accordance

34、 with Section 11.2f and 11.3e. 2 Tailoring Tailoring of this document is allowed to meet specified requirements. Wherever tailoring is proposed to a requirement herein, the rationale shall be stated and agreed upon. Written customer approval of the tailored sections is required. 3 Applicable Documen
