Mechanical structures for electronic equipment - Dimensions of mechanical structures of the 482,6 mm (19 in) series - Part 3-105: Dimensions and design aspects for 1U high chassis
电子设备机械结构 - 482,6 Mm(19 In)系列机械结构尺寸 - 第3-105部分:尺寸和设计方面1u高底盘
IEC 60297-3-105:2008 specifies the dimensions for 1U chassis mounted into IEC 60297-3-100 compliant racks/cabinets where dimensions, loaded weight and accessibility require differing assembly methods. Guidance for cooling and reference for EMC, seismic and for the climatic and mechanical requirements and tests are provided, as defined in the IEC 61587 series.
