ECSS-E-ST-31 defines requirements for the discipline of thermal engineering.
This Standard defines the requirements for the definition, analysis, design, manufacture, verification and in-service operation of thermal control subsystems of spacecraft and other space products.
For this Standard, the complete temperature scale is divided into three ranges:
- Cryogenic temperature range
- Conventional temperature range
- High temperature range.
The requirements of this Standard are applicable to the complete temperature scale. However, where applicable, requirements are stated to be applicable only for the cryogenic or high temperature range. References to these specific requirements have been summarized in Annex G and Annex H.
This standard is applicable to all flight hardware of space projects, including spacecraft and launchers.
This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.
