ISO 14620-1:2002定义了为遵守ISO 14300-2中定义的安全政策而实施的安全计划和技术安全要求。其目的是保护飞行和地面人员、运载火箭、相关有效载荷、地面支持设备、公共、公共和私人财产以及环境免受与空间系统相关的危害。发射场操作由ISO 14620-2描述。通过实施系统安全计划来实施安全政策，并辅以风险评估，风险评估可总结如下:通过反复进行系统安全分析，识别并逐步评估具有潜在危险失效影响的危险特性（系统和环境危害）和功能；与系统特性和功能故障相关的潜在危险后果应遵循危险降低顺序，从而从系统设计和运行中消除危险，将危险降至最低，并应用和验证危险控制；逐步评估并接受风险评估，以证明符合安全目标、支持设计交易、识别和评级风险因素、支持项目资源分配以降低风险、评估风险降低进度，并支持安全和项目决策过程（例如豁免批准、剩余风险接受）；正式验证所采用的危害和风险控制措施的充分性，以支持安全验证和风险接受；安全合规性由项目评估，并获得相关部门的安全批准。ISO 14620-1:2002适用于在任何项目阶段对人员或公众、空间飞行系统、地面支持设备、设施、公共或私人财产或环境存在潜在危害的所有空间项目。将这些要求强加给项目供应商的活动要求客户的项目产品保证和安全组织也以与项目安全关键性相称的方式响应这些要求。当从特定计划或项目背景的角度来看时，ISO 14620-1:2002中定义的要求应根据计划或项目的特定概况和环境的真实要求进行调整。

ISO 14620-1:2002 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.The safety policy is applied by implementing a system safety programme, supported by risk assessment, which can be summarized as follows: hazardous characteristics (system and environmental hazards) and functions with potentially hazardous failure effects are identified and progressively evaluated by iteratively performing systematic safety analyses; 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; 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); the adequacy of the hazard and risk control measures applied are formally verified in order to support safety validation and risk acceptance; safety compliance is assessed by the project and safety approval obtained from the relevant authorities.ISO 14620-1:2002 is applicable to all space projects where during any project phase there exists the potential for hazards to personnel or the general public, space flight systems, ground support equipment, facilities, public or private property, or the environment.The imposition of these requirements on the project suppliers' activities requires that the customer's project product assurance and safety organization also respond to these requirements in a manner which is commensurate with the project's safety criticality.When viewed from the perspective of a specific programme or project context, the requirements defined in ISO 14620-1:2002 should be tailored to match the genuine requirements of a particular profile and circumstances of a programme or project.
