What is BS EN 60297-3-106 - Dimensions of subracks and chassis about? 
Electronic systems based on chassis design have become one of the most important platforms used for servers, industrial electronics, information technology (IT) and telecommunication equipment. The IEC 60297 series of standards provides definitions of mechanical structure and dimensions for 19 in cabinets and racks and their compatible subracks and chassis. The combination of 19 in based cabinets or racks and subracks and chassis is broadly applied to all industrial electronic fields in the world.
BS EN 60297-3-106 specifies dimensions for mounting flanges of 19 in subracks or chassis that are to be mounted into metric cabinets or racks. Additional dimensions for subracks or chassis are according to the IEC 60297 series, and for metric cabinets or racks to the IEC 60917 series.
EMC, seismic, climatic and environmental requirements and tests, are defined in the IEC 61587 series. The drawings used in BS EN 60297-3-106 do not intend to indicate product design, only the specific dimensions that should be used. The terminology used in BS EN 60297-3-106 complies with IEC 60917-1.
