ISO 17763:2018

Overview

ISO 17763:2018 - Space systems: Human-life activity support systems and equipment integration in space flight is the first‑level, top‑level standard defining a coherent framework for habitability and life‑support integration across human space flight programmes. It establishes the scope, structure and general techno‑medical requirements for human habitation environments in spacecraft, space stations, lunar/planetary bases and extravehicular activity (EVA). The standard applies to all development phases - design, production, testing, operation and maintenance - and supports long‑term missions (up to 3 years).

Key Topics and Requirements

• Three‑level standard structure: ISO 17763 is the first level; second‑level documents define techno‑medical requirements; third‑level documents contain task‑specific requirements (Annex A explains the concept).
• Applicability and conformance: Requirements apply to all manned space objects and phases of flight programmes. Programs must define verifiable, program‑specific requirements and perform permanent monitoring and verification of conformance.
• Human habitation environment: Defines concepts for material, energy and information flows in pressurized habitable compartments, addressing physiological, comfort, safety and hygiene needs.
• Techno‑medical requirements: Covers biomedical, hygiene/sanitary, ergonomic, design and construction requirements to support crew health, safety and operational efficiency.
• Life‑support approaches: Acknowledges current reliance on physico‑chemical regeneration systems for oxygen, water and waste processing; recognizes biological closed‑loop environments as future objectives.
• Supply and maintenance: Specifies that habitation conditions must be provided and maintained at required levels throughout mission lifecycle; verification through hardware tests and operational monitoring is mandated.
• Scope limits: Addresses crew medical fitness prerequisites and permits controls for experimental equipment, materials and unmanned systems operated in crewed compartments.

Practical Applications and Users

Who uses ISO 17763:

• Space agencies (mission architects and programme managers)
• Life Support System (LSS) designers and systems integrators
• Spacecraft and habitat manufacturers
• Medical and human factors engineers (techno‑medical teams)
• Test, verification and certification authorities
• Safety, operations and maintenance personnel

How it’s used:

• Defining habitability and safety requirements early in design
• Integrating life‑support equipment with vehicle architecture
• Developing verification and monitoring plans for flight programmes
• Guiding procurement and acceptance of crew‑used hardware and experiments

Related Standards

• Second‑level standards: Techno‑medical requirements for spacecraft crew habitation environment (detailed biomedical and environmental requirements, including spacesuit considerations)
• Third‑level standards: Task‑specific normative documents supporting the second level
