IAASS-SSI-1700 Commercial Human-Rated System
These requirements are intended to protect the flight personnel (i.e., crew and flight participants), the vehicle and relevant launcher or carrier, and any other interfacing system from CHS-related hazards. This document contains technical and system safety program requirements applicable to the CHS development and flight operations. CHS ground operations, interfacing ground systems, and ground support equipment (GSE) safety certification is outside the scope of this standard.
The technical requirements in this standard are applicable to the CHS, which, depending on the phase of the mission, is either the crewed vehicle or the composite (i.e., vehicle integrated on launcher or carrier). They apply also to external interfaces (e.g., with control centers, launch pad, recovery system). The requirements apply to all phases of the mission, including docking to a crewed station. The applicability of these requirements and their apportionment to CHS system functions, elements, and external interfaces, will be determined by the safety analysis.
Unique safety requirements for launchers and carriers mandated by national regulations, and unique safety requirements for the phases when they operate separately from the vehicle are outside the scope of this standard. Furthermore, all requirements related to public safety are outside the scope of this standard, in particular during launch, air-carried/air-launch, and re-entry phases.
This document establishes the safety requirements applied by the IAASS Space Safety Institute (SSI) for the safety certification of Commercial Human Rated Systems (CHS). This standard covers any human-rated system commercially developed and operated to perform suborbital, orbital, or interplanetary missions, including transport vehicles such as capsules or winged bodies, orbital stations, unmanned cargo transport vehicles intended to dock with crewed stations, bases, descent and ascent vehicles, and integrated systems (e.g., capsule on launcher). NOTE: The mandatory (i.e., shall) requirements in this standard are based on selected best practices from past and present governmental space programs.
