This standard is under the jurisdiction of the National Committee on Standardization of Space Science and Its Application (SAC/TC312). The drafting of this standard.

General specification for space biology experimental device

1 Scope

China's national design specification for space biology experiment facilities - the sealed, instrumented boxes flown on spacecraft in which cells, plants or small animals are kept alive, exposed to microgravity and then observed or fixed, so that what comes back is a specimen rather than a failure. It specifies the design principles, the design flow, the design method and the design verification of biological experiment facilities for space, and it applies to the design of the biological experiment facilities used aboard spacecraft; the design of other facilities for space biology experiments may follow it by reference. The specification is built around the units such a facility has to contain. The biological unit holds the specimen. The biological containment unit keeps it separated from the crew and the spacecraft in both directions, which on a crewed vehicle is the requirement that governs the design. The sample fixation unit stops the biology at a defined moment, since a specimen that continues to live and change on the way home is not the specimen the experiment intended. The data acquisition and control unit and the monitoring unit record what was actually done to the specimen and what happened to it, because in orbit there is no possibility of repeating an observation. To those are added the software design, the design for reliability, safety and maintainability, and the ergonomic design that decides whether the crew can operate the facility in a pressure suit and in a confined volume. The verification clause then requires that the mission functions and performance be demonstrated, that the matching tests with the spacecraft be carried out, and that the facility be verified before installation and again after recovery. Issued on 14 June 2016 and in force since 1 September 2016, it is held by SAC/TC 312 and was drafted by the Shanghai Institute of Technical Physics of the Chinese Academy of Sciences.

This standard specifies the design principles, design flow, design method and design of the space biology experimental device (hereinafter referred to as the experimental device) verification. This standard applies to the design of biological experimental devices used in spacecraft, and other experimental applications for space biology experiments Design can refer to use.
