Abstract: Based on the high reliability requirements of spacecraft products and characteristics of small samples, and according to the top-level development and testing requirements of products as the theme template, a set of novel standardized models for test data management were proposed. They include data confidence management model, small sample product data screening model, as well as performance data management model. The secondary power supply product of spacecraft was taken as the application object to establish the standardized models for performance test data. The previous fragmented test data were summarized and the dimensions were unified. The proposed study can be used for horizontal comparison of batch production and vertical comparison of generation development for spacecraft, so as to offer reliable information for the subsequent use of test data.
