ECSS-E-ST-30 is a European space standard that provides a framework for electrical and electronic requirements for space projects. The standard covers a wide range of electrical and electronic components, subsystems, and systems that are used in space projects, including power systems, communication systems, data handling systems, and sensors. It defines the electrical and electronic design, manufacturing, testing, and verification processes that are required to ensure the reliability and safety of space systems including component selection and qualification, as well as testing and analysis methods. It provides specific requirements for each component or subsystem, including the design and performance requirements, the qualification and acceptance testing, and the documentation requirements.

One of the key aspects of ECSS-E-ST-30 is the emphasis on the reliability and safety of electrical and electronic systems in space. This includes the development of redundant and fault-tolerant systems, as well as the use of radiation-hardened components and materials that can withstand the harsh space environment. The standard also covers the manufacturing processes for electrical and electronic components and systems, including the quality assurance requirements, the testing and inspection requirements, and the documentation requirements. It provides guidelines for the selection of manufacturing processes and materials that are appropriate for space applications, as well as the verification and validation of the manufacturing processes.

In addition to the design and manufacturing processes, ECSS-E-ST-30 also covers the testing and verification processes for electrical and electronic systems. This includes the development of test plans and procedures, as well as the documentation of the test results. It also covers the environmental testing requirements, such as thermal cycling and vibration testing, to ensure that the electrical and electronic systems can withstand the harsh conditions of space.
