31、, subracks, chassis and plug-in units based on metric modular ordered dimensions. The later developed IEC 60917 series of standards, compared to IEC 60297, provides more logical design practices based on metric dimensioning. The IEC 60297 series of standards also define structures and interface dime

32、nsions for 19 in cabinets, racks and their compatible subracks and chassis. Because of the longer history of the IEC 60297 series of standards and their applications, the combination of 19 in based cabinets, racks, subracks and chassis are broadly applied for all industrial electronic fields in the

33、world. Requests for combined applications with both mechanical structures, the IEC 60917 series (metric standard) and the IEC 60297 series (19 in standard), resulted in requirements to mount metric subracks or chassis into 19 in standard cabinets or racks and, vice versa, 19 in subracks or chassis i

34、nto metric cabinets or racks. To cope with the requirements and needs, it is required to develop definitions for appropriate adaptation dimensions of flanges for metric or 19 in subracks or chassis to mount them into cabinets or racks in accordance with 19 in or metric standard. And the definitions

35、of adaptation dimensions bring economical solutions for installations of electronic equipment into existing cabinets or racks. Further, they provide guidance to electro-mechanical designers to develop systems suitable to be mounted into both IEC standard series flexibly. To meet such market needs, t

36、his standard defines adaptation dimensions for metric subracks or chassis applicable for 19 in cabinets or racks. (Dimensions for the applications, where 19 in subracks or chassis are mounted on metric cabinets or racks, are defined in a separate standard, i.e. IEC 60297-3-106.) BS EN 60917-2-4:2010
