GB/T 43457—2023 "Requirements for the Preparation and Installation of Space Science Experimental Samples before Launch" is an important standard in China's aerospace field. It mainly regulates the preparation and installation process of space science experimental samples before launch. This standard is applicable to experimental operations in the fields of manned spaceflight, space life sciences, materials science, etc.
With the rapid development of China's aerospace industry, the demand for space science experiments is increasing. In order to ensure the safety and effectiveness of experimental samples during launch and on-orbit experiments, it is necessary to formulate unified technical specifications. This standard was proposed by the Chinese Academy of Sciences and is managed by the National Technical Committee for Space Science and Its Application Standardization.
| Dimensions | GB/T 43457—2023 | Comparison with international standards |
|---|---|---|
| Scope of application | Requirements for pre-launch preparation and installation of space science experimental samples | In line with international aerospace standards, filling domestic gaps |
| Technical indicators | Detailed specifications for sample preparation, loading, transportation and installation processes | Some indicators reach or exceed international levels |
| Safety requirements | Emphasis on the safety management of experimental samples to prevent potential threats to spacecraft and operators | Comply with global aerospace safety standards |
This standard emphasizes the principle of "safety first", requiring only necessary work to be carried out at the launch site, and ensuring that the operating environment does not cause contamination to samples, equipment or personnel. At the same time, it clearly requires that the status management of experimental samples must be uniquely identified and traceable.
Special attention should be paid to the sealing problem during the preparation of fluid or combustion experimental samples. According to the standard requirements, all sample containers must undergo a sealing test and take electrostatic protection measures during the loading process.
The release of GB/T 43457—2023 marks an important step forward for China in the construction of aerospace standardization. This standard not only provides clear technical guidance for the pre-launch preparation and installation of experimental samples, but also provides a strong guarantee for the safety and reliability of future space science experiments.
