本标准涉及环境控制和生命支持（ECLS）的纪律以及与其他工程学科，管理和产品保证领域的接口。 它还介绍了相关3级标准的结构和适用性。 本标准涵盖的环境控制和生命支持系统（ECLSS）包括与为进行太空任务的人类提供安全舒适的环境保证有关的方面。 当其他形式的生活在船上时，ECLSS也确保这些生物体的适当的环境条件。 本标准适用于以下所有ECLSS: - 所有载人空间努力和人造空间产品，以及 - 任何其他形式的生命要维持在船上。 该标准可能针对符合ECSS-S-ST-00的空间项目的具体特征和限制

This Standard 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 man­rated space products, and - any other form of life to be maintained on board. This standard may be tailored for the specific characteristics and constrains of a space project in conformance with ECSS-S-ST-00.
