标准摘要
[中文适用范围]： IEC 60297 的这一部分规定了机箱和相关印刷板的尺寸和物理属性，以便为嵌入式计算设备提供机械和环境完整性。它们用于机器控制、医疗、运输、航空航天和电信等各种应用，通常基于单板计算机。为了轻松定义合适的机箱和相关的单板尺寸，该标准基于 44.45 毫米（1.75 英寸）的结构网格。 [外文原描述]： IEC 60297-3-109:2015 specifies dimensions and physical properties of chassis and associated printed boards in order to provide mechanical and environmental integrity for embedded computing devices. They are used in various applications such as machine control, medical, transportation, aerospace and telecommunication, typically based on single board computers. For the easy definition of the suitable chassis and associated single board dimensions, this standard is based on a structural grid of 44,45 mm (1,75 in). Key words: Dimensions, Mechanical Structures, Chassis, Embedded Computing Devices
英文名称Mechanical structures for electrical and electronic equipment - Dimensions of mechanical structures of the 482,6 mm (19 in) series - Part 3-109: Dimensions of chassis for embedded computing devices
