1.1这些实践的目的是为舱室和人孔设计提供标准，以及有关机械、生命支持、控制、通信和应急系统以及相关医疗设施的信息。 1.2除设计标准外，还规定了这些设施的正确操作指南。这些指南是基于迄今为止作为双子座和阿波罗计划的一部分，由各种设施进行的载人试验操作所积累的大量经验。 1.3本标准无意解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

1.1 The purpose of these practices is to provide criteria for chamber and manlock design, as well as information concerning mechanical, life-support, control, communications and emergency systems, and associated medical facilities. 1.2 In addition to design criteria, guidelines for the proper operation of these facilities are set forth. Such guidelines are based on the considerable experience accumulated to date by the manned test operations conducted by various facilities as part of the Gemini and Apollo programs. 1.3 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 and health practices and determine the applicability of regulatory limitations prior to use.
