1.1 意图: 1.1.1 本标准旨在为远程热电池环境中使用的机械驱动系统的设计、选择、质量保证、安装、操作和维护提供一般指南。本文中使用的术语机械驱动系统包括用于向设备系统、子系统、组件和其他组件传递运动的所有单个组件。它还包括完整的定位系统和单个单元，提供动力和监测运动所需的任何位置指示器。 1.2 适用性: 1.2.1 本标准适用于在以下一种或多种条件下使用的设备: 1.2.1.1 处理或加工的材料对人类或环境构成重大辐射危害。 1.2.1.2 设备通常将在长期寿命周期内使用（例如，超过两年），但不排除在较短寿命周期内的设备。 1.2.1.3 设备既不能直接用于操作或维护，也不能直接查看设备，例如，没有辐射屏蔽窗口、潜望镜或视频监控系统（指南 C1572 和 C1661 ). 1.2.2 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不是精确的等效值；因此，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。 1.3 用户注意事项: 1.3.1 本标准不能替代应用工程技能、经验证的实践和经验。其目的是提供指导。 1.3.1.1 本标准中规定的与设备设计有关的指南仅旨在提醒设计师和工程师注意那些对于设计、选择、操作和维护适用于特定使用条件的机械传动系统而言是必要的或非常可取的特征、条件和程序。 1.3.1.2 该指南阐述了发现操作或维护问题或故障原因的条件、实践、特征或缺乏特征的结果。 1.3.2 本标准不取代任何条件下适用于设备的联邦或州法规或两者以及规范。 1.3.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户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。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 机械驱动系统的可操作性和长期完整性是设计阶段应主要解决的问题；然而，应解决制造和测试期间发现的问题，并记录设计变更。在搬运和安装过程中，设备的可操作性和完整性可能会受到影响。因此，应在严格控制和监督的条件下搬运和安装受试设备。 4.2 本标准旨在作为其他标准以及适用于该用途设备设计的联邦和州法规、规范和标准的补充。 4.3 本标准为通用标准，适用于各种类型和配置的机械传动系统。

1.1 Intent: 1.1.1 The intent of this standard is to provide general guidelines for the design, selection, quality assurance, installation, operation, and maintenance of mechanical drive systems used in remote hot cell environments. The term mechanical drive systems used herein, encompasses all individual components used for imparting motion to equipment systems, subsystems, assemblies, and other components. It also includes complete positioning systems and individual units that provide motive power and any position indicators necessary to monitor the motion. 1.2 Applicability: 1.2.1 This standard is intended to be applicable to equipment used under one or more of the following conditions: 1.2.1.1 The materials handled or processed constitute a significant radiation hazard to man or to the environment. 1.2.1.2 The equipment will generally be used over a long-term life cycle (for example, in excess of two years), but equipment intended for use over a shorter life cycle is not excluded. 1.2.1.3 The equipment can neither be accessed directly for purposes of operation or maintenance, nor can the equipment be viewed directly, for example, without radiation shielding windows, periscopes, or a video monitoring system (Guides C1572 and C1661 ). 1.2.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.3 User Caveats: 1.3.1 This standard is not a substitute for applied engineering skills, proven practices and experience. Its purpose is to provide guidance. 1.3.1.1 The guidance set forth in this standard relating to design of equipment is intended only to alert designers and engineers to those features, conditions, and procedures that have been found necessary or highly desirable to the design, selection, operation and maintenance of mechanical drive systems for the subject service conditions. 1.3.1.2 The guidance set forth results from discoveries of conditions, practices, features, or lack of features that were found to be sources of operational or maintenance problems, or causes of failure. 1.3.2 This standard does not supersede federal or state regulations, or both, and codes applicable to equipment under any conditions. 1.3.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 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 ====== 4.1 Mechanical drive systems operability and long-term integrity are concerns that should be addressed primarily during the design phase; however, problems identified during fabrication and testing should be resolved and the changes in the design documented. Equipment operability and integrity can be compromised during handling and installation sequences. For this reason, the subject equipment should be handled and installed under closely controlled and supervised conditions. 4.2 This standard is intended as a supplement to other standards, and to federal and state regulations, codes, and criteria applicable to the design of equipment intended for this use. 4.3 This standard is intended to be generic and to apply to a wide range of types and configurations of mechanical drive systems.
