This document defines the safety programme and the technical safety requirements that are implemented in order to comply with the safety policy as defined in ISO 14300‑2. It is intended to protect flight and ground personnel, the launch vehicle, associated payloads, ground support equipment, the general public, public and private property, and the environment from hazards associated with space systems. Launch site operations are described by ISO 14620‑2 and flight safety systems in ISO 14620‑3. The safety policy is applied by implementing a system safety programme, supported by risk assessment, which can be summarized as follows. a) Hazardous characteristics (system and environmental hazards) and functions with potentially hazardous failure effects are identified and progressively evaluated by iteratively performing systematic safety analyses. b) The potential hazardous consequences associated with the system characteristics and functional failures are subjected to a hazard reduction sequence whereby: hazards are eliminated from the system design and operations; hazards are minimized; and hazard controls are applied and verified. c) The risks that remain after the application of a hazard elimination and reduction process are progressively assessed and subjected to risk assessment, in order to: show compliance with safety targets; support design trades; identify and rank risk contributors; support apportionment of project resources for risk reduction; assess risk reduction progress; and support the safety and project decision-making process (e.g. waiver approval, residual risk acceptance). d) The adequacy of the hazard and risk control measures applied are formally verified in order to support safety validation and risk acceptance. e) Safety compliance is assessed by the project and safety approval obtained from the relevant authorities.
Abstract
Overview
ISO 14620-1:2018 - Space systems - Safety requirements - Part 1: System safety - defines the system safety programme and the technical safety requirements used to implement the safety policy (as defined in ISO 14300‑2). Its purpose is to protect flight and ground personnel, the launch vehicle and payloads, ground support equipment, the public, property and the environment from hazards associated with space systems. The standard describes an iterative hazard identification, hazard reduction and risk assessment process, ending with formal verification, validation and safety approval.
Key topics and technical requirements
The standard covers the full system-safety lifecycle and includes requirements for:
- System safety programme: scope, organization, roles (safety representative), authority, reporting lines and coordination with stakeholders.
- Safety risk management: systematic hazard identification, iterative safety analyses, hazard elimination/minimization, application and verification of controls.
- Safety engineering principles: design selection, order of precedence for hazard control, fail-safe concepts, environmental compatibility, and “safe without services” design considerations.
- Failure tolerance & redundancy: requirements for failure tolerance, separation of redundant elements, failure propagation control and design for minimum risk.
- Identification of safety-critical functions: classification, provisions to prevent inadvertent operation, and shutdown/failure tolerance requirements.
- Safety analysis techniques: mission and feasibility analysis, allocation of safety requirements to functions and subsystems, and justification of safety requirements.
- Safety programme elements: safety planning, training, certification, documentation (safety data package), accident/incident reporting and lessons-learned tracking.
- Verification and acceptance: verification tracking, risk assessment to demonstrate compliance with safety targets, support for design trades, waiver/residual risk processes and safety approval by authorities.
Practical applications
ISO 14620-1:2018 is used to:
- Develop and implement a system safety programme for spacecraft, launch vehicles and support systems.
- Define and allocate technical safety requirements across system, subsystem and interface levels.
- Perform structured hazard analyses and risk assessments to support design trades and safety decisions.
- Prepare safety documentation and verification evidence required for safety certification and regulatory acceptance.
Who should use this standard
- Spacecraft and launch vehicle system engineers and safety engineers
- Launch site operators and ground support engineers
- Project managers, integrators and suppliers/sub‑suppliers
- Regulatory authorities and safety certification bodies
