EN 14607 Part 5.1 of Space engineering - Mechanical defined the requirements for the discipline liquid and electric
propulsion for spacecraft
This document belongs to the propulsion field of the mechanical discipline, as defined in EN 13292, and defines the
regulatory aspects applicable to elements and processes for liquid, including cold gas, and electrical propulsion for
spacecraft. It specifies the activities to perform in the engineering of such propulsion systems, their applicability,
and defines the requirements for the engineering aspects: functional, configurational, interfaces, physical,
environmental, quality factors, operational and verification.
General requirements relating to Mechanical Engineering are defined in EN 14607 Part 1.
This document applies only to liquid, including cold gas, and electrical propulsion systems used in spacecraft and
to related mechanical parts. Solid propulsion for spacecraft, and solid and liquid propulsion for launchers are not
covered by this document.
Other forms of propulsion currently under development (e.g. nuclear, nuclear-electric, solar-thermal and hybrid
propulsion) are not presently covered by this document.
When viewed in a specific project context, the requirements defined in this document should be tailored to match
the genuine requirements of a particular profile and circumstances of a project.
NOTE Tailoring is a process by which individual requirements of specifications, standards and related documents
are evaluated and made applicable to a specific project, by selection and in some exceptional cases, modification
of existing or addition of new requirements.
