序言这是信息技术设备的通用CSA和UL标准-安全-第23部分:大型数据存储设备。这是CAN/CSA-C22的第一版。2第60950-23号和第一版UL 60950-23。本标准基于IEC 60950-23第一版。1.范围IEC 60950的本部分规定了信息技术设备（ITE）的要求，该设备具有包含危险移动部件的自包含数据存储系统。这些数据存储系统通常足够大，允许人员完全进入，但是，这些系统还包括类似的大型设备，允许完整的肢体或头部进入包含危险移动部件的区域。 这些要求是对IEC 60950-1中相关要求的补充。弹药筒附件组件的最大三维范围通常具有0.75 m3或以上的最小运动包络。设备应安装在受限访问位置，如数据中心。IEC 60950-1第1.2.7.3条中提到的2.1.3和4.5.4（IEC 60950-1第一版中的4.5.1）的例外情况不适用于本第23部分。注1:本范围内设备的一个例子是自动信息海量存储和检索系统，该系统使用完整的危险移动部件来处理记录的介质（例如盒式磁带、盒式磁带、光盘等）。 )以及类似的功能。本标准不适用于带有非独立危险运动部件的设备，例如安装在工业环境中的机器人设备。注2:有关工业环境中机器人设备的相关标准，请参见IEC 60204-1、IEC 60204-11和ISO 10218。

PrefaceThis is the common CSA and UL Standard for Information Technology Equipment - Safety - Part 23: Large Data Storage Equipment. It is the first edition of CAN/CSA-C22.2 No. 60950-23 and the first edition of UL 60950-23. This standard is based on IEC 60950-23, first edition.1. ScopeThis part of IEC 60950 specifies requirements for information technology equipment (ITE) with self contained data storage systems that contain hazardous moving parts. These data storage systems are typically large enough to permit a person to enter completely, however, the systems also include similar large equipment permitting complete limb or head access to the area containing hazardous moving parts. These requirements are additional to the relevant requirements in IEC 60950-1. The maximum three dimensional reach of a cartridge accessory assembly typically has a minimum motion envelop of 0,75 m3 or more.The equipments shall be installed in a RESTRICTED ACCESS LOCATION, such as a data centre. The exceptions for 2.1.3 and 4.5.4 (4.5.1 in IEC 60950-1, first edition) noted in 1.2.7.3 of IEC 60950-1 do not apply to this Part 23.NOTE 1 An example of equipment covered by this scope is an automated information mass storage and retrieval system that uses integral hazardous moving parts for the handling of recorded media (for example, tape cartridges, tape cassettes, optical disks, etc.) and similar functions.This standard is not applicable to equipment with non-self-contained hazardous moving parts, such as robotic equipment installed in an industrial environment.NOTE 2 For standards related to robotic equipment in an industrial environment, see IEC 60204-1, IEC 60204-11 and ISO 10218.
