1.1 本指南介绍了在亚轨道上搭载机组人员、太空飞行参与者、任务专家或其他人类的亚轨道航天器的设计。 1.2 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.3 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ===意义和用途====== 5. 1. 本指南旨在供开发亚轨道航天器的设计团队使用。它包含了通过技术界的经验已知的设计主题的共识，这是在设计过程中必须注意的最低限度，以确保人类安全飞行和返回地球的高概率。

1.1 This guide addresses the design of suborbital space vehicles that carry flight crew, spaceflight participants, mission specialists or other humans on suborbital trajectories. 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This guide is intended to be used by design teams developing suborbital space vehicles. It contains a consensus of the design topics known through experience of the technical community to be the minimum to which attention must be paid during the design process to ensure a high probability of safe flight and return to Earth of humans.
