The additional requirements were publis
23、hed inIEC 60297-4:1995 with A mendment 1:1999.The extended requirements were published in the IEC 60297-5-1XX series (2001).Responding to market requirements and for more clar ityitbecame necessary t o merge andtechnically enhance these standard “parts”into3 “new” standards for subracks andassociate
24、d plug-in units. This “merged”standard series now defined as IEC 60297-3-101,IEC60297-3-102 and IEC 60297-3-103 explains its relationship tothe previous “fragmented”IEC60297-X standards, see Figure 1.The nomenclature ofthese new standards has beenrevised. The relationship to IEC 60297-1(Part 1: Pane
25、lsand Racks) has been maintained. The relationship to IEC 60297-2 (Part 2:Cabinets and pitches of rack structures) hasbeen maintained. The relationship to IEC 61587-1(Part 1: Climatic, mechanical tests and safety aspects for cabinets, racks, subracks andchassis) and IEC TS 61587-3 (Part 3: Electroma
26、gnetic shielding performance tests forcabinets, racks and subracks) has been added.The IEC60297-3-101 standard defines the interfaces ofthe basic 482,6 mm (19 in) subrackand associated plug-in units.Figure 1 Relationship between the newIEC 60297-3 series and the old IEC 60297 seriesSubracks and plug
