This Standard is the Part 4 of ECSS-E-30 (Space engineering – Mechanical). It addresses the discipline of environmental control and life support (ECLS) and the interfaces to other disciplines of engineering and to the domains of management and product assurance.
It also introduces the structure and applicability of the associated Level 3 Standards.
The environmental control and life support systems (ECLSS) covered in this Standard includes those aspects relating to the assurance of a safe and comfortable environment for human beings undertaking a space mission.
When other forms of life are accommodated on board, the ECLSS also ensures the appropriate environmental conditions for those living organisms.
This Standard applies to all ECLSS for:
- all manned space endeavours and man-rated space products as defined in ECSS-E-00, and
- any other form of life to be maintained on board.
When viewed from the perspective of a specific project context, the requirements defined in this standard should be tailored tomatch the genuine requirements of a particular profile and circumstances of a project.
NOTE Tailoring is a process by which individual requirements or 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.
