标准摘要
[中文适用范围]： IEC 60297 的这一部分提供了 R 型子架和插入式单元@的尺寸和特性，即 482@6 毫米（19 英寸）系列@机械结构的加固型变体，具有增强的抗振性和抗冲击性和/或改进的 EMC Performance@适用于更恶劣的环境。这导致了一个子架标准，其外部与 IEC 60297-3-100 兼容，但内部与 IEC 60297-3-101 很大程度上不兼容。与 IEC 60297-3-101（测试设置和负载定义选自 IEC 61587-1 和IEC 61587-5）。 [外文原描述]： IEC 60297-3-108:2014 provides dimensions and features for R-type subracks and plug-in units, i.e. ruggedized variants of the mechanical structures of the 482,6 mm (19 in) series, with enhanced vibration and shock resistance and/or improved EMC performance, for use in more harsh environment. This leads to a subrack standard which is externally compatible with IEC 60297-3-100 but internally largely incompatible with IEC 60297-3-101. R-type subracks, chassis integrated subracks and plug-in units incorporate dimensions and features which provide for a higher level of ruggedness, compared with IEC 60297-3-101 (test set-up and load definitions are selected from IEC 61587-1 and IEC 61587-5). Key words: R-Type, Subracks, Plug-in unit
英文名称Mechanical structures for electronic equipment - Dimensions of mechanical structures of the 482,6 mm (19 in) series - Part 3-108: Dimensions of R-type subracks and plug-in units
