测量、控制和实验室用电气设备的安全要求.第2-091部分:机柜X射线系统的特殊要求，除以下情况外:1.1.1范围内包含的设备替换:将文本替换为以下内容:机柜X射线系统是一个包含安装在机柜中的X射线管的系统，该系统独立于现有建筑结构（可能放置X射线管的地板除外），旨在包含至少一部分被辐照的材料，提供辐射衰减，并在产生X射线时将人员从内部排除。这些柜式X射线系统用于工业、商业和公共环境，例如检查材料、分析材料和筛选行李。 1.1.2不在范围内的设备添加:将以下新项目添加到列表中:aa）拟向人类或动物施加X射线的设备；bb）装有X射线管但未完全屏蔽X射线危害的设备，例如:拟在屏蔽室内使用的设备，操作期间不包括人员；拟与单独便携式或临时屏蔽一起使用的设备；用于产生X射线的设备。1.2.1范围中包含的方面补充:在第一段末尾添加以下内容:IEC 61010的本部分规定了机柜X射线系统的设计和施工方法要求，以便为操作员、旁观者、经过培训的服务人员和周围区域提供足够的保护，防止意外伤害- X射线辐射和与输送机相关的机械危险。

Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use - Part 2-091: Particular Requirements for Cabinet X-Ray SystemsUL 61010-2-091 (IEC 61010-2-091:2012)1 Scope and objectThis clause of Part 1 is applicable, except as follows:1.1.1 Equipment included in scopeReplacement:Replace the text with the following:A CABINET X-RAY SYSTEM is a system that contains an X-ray tube installed in a cabinet which, independently of existing architectural structures except the floor on which it may be placed, is intended to contain at least that portion of a material being irradiated, provide radiation attenuation, and exclude personnel from the interior during generation of X-radiation.These CABINET X-RAY SYSTEMS are used in industrial, commercial, and public environments, for example, to inspect materials, to analyze materials, and to screen baggage.1.1.2 Equipment excluded from scopeAddition:Add the following new items to the list:aa) equipment intended to apply X-radiation to humans or animals;bb) equipment incorporating an X-ray tube but not incorporating complete shielding against X-radiation hazards, such as:equipment intended to be used within a shielded room which excludes personnel during operation;equipment intended to be used with separate portable or temporary shielding;equipment intended to produce an emerging beam of X-radiation.1.2.1 Aspects included in scopeAddition:Add the following text at the end of the first paragraph:This part of IEC 61010 specifies requirements for the design and methods of construction of CABINET X-RAY SYSTEMS to provide adequate protection for OPERATORS, bystanders, trained service personnel, and the surrounding area against unintentionally-emitted X-radiation and from mechanical HAZARDS related to their conveyors.
