IEC 60917-1:20 19 RLV包含官方IEC国际标准及其红线版本。Redline版本仅提供英文版本，为您提供了一种快速简单的方法来比较IEC官方标准与其以前版本之间的所有变化。 IEC 60917-1:20 19规定了设备实践和模块化顺序之间的关系，这些关系适用于安装在各种装置中的电子和电气设备的主要结构尺寸，其中必须考虑尺寸接口以实现机械兼容性。该文件还为电气和电子设备的机械结构的零件和组件建立了术语，以阐明设备实践和模块化订单之间的具体关系。本第二版取消并取代1998年出版的第一版及其修正案1:2000.本版是技术性修订。与上一版相比，此版本包括以下重大技术变更: a)为电气和电子设备实践添加了有关新制定的机械结构详细规范标准的信息； b)添加了有关新制定的性能测试标准的信息，用于验证电气和电子设备实践的环境性能和安全方面以及热性能和热管理问题； c)介绍了电气和电子系统的机械结构、环境性能和安全验证之间的关系以及电气和电子设备实践中的热性能和热管理问题。 关键词:IT机柜,机械结构

IEC 60917-1:2019 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60917-1:2019 specifies the relationships between equipment practices and the modular order which are applicable to the main structural dimensions of electronic and electrical equipment mounted in various installations where dimensional interfaces have to be considered for mechanical compatibility. This document also established terms for parts and assemblies of mechanical structures for electrical and electronic equipment, to clarify the specific relations between equipment practices and modular order. This second edition cancels and replaces the first edition published in 1998 and its Amendment 1:2000. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) added information on newly developed detail specification standards of mechanical structures for the electrical and electronic equipment practices;
b) added information on newly developed performance test standards for the verifications of environmental performances and safety aspects and issues of the thermal performance and thermal management for the electrical and electronic equipment practices;
c) introduced the relations between the mechanical structure for electrical and electronic system, the verification of environmental performance and safety aspects and issues of the thermal performance and thermal management for the electrical and electronic equipment practices.
