Standards Summary2Introduction to the Standards SummaryWhy is Schroff committed to standardsand modular concepts?Commercial electronic devices are investmentswith relatively long life cycles,where highreliability and availability are predominantrequirements.In order to keep the cost low and atthe same time maintain a very high quality level,standard designs with predefined performancelevels are indispensable.Subracks, cases andcabinets are structural parts ofany equipment.Thestandards philosophy allows short developmenttime and fast market introduction for theseproducts without expensive development,testingand validation procedures.Are standard product platforms as flexibleand cost effective as proprietary designs?If a certain product with relatively high quantitiesand a long, steady lifecycle is demanded,mostlikely a proprietary design will be favorable.Butfor most electronics markets the requiredinvestments are too high for proprietary designs,if we consider all development and sourcing costsrealistically. Standard product platforms typicallyconsist of a modular concept which provides awide variety of off-the-shelf products.Contents of the standards summaryThis standards summary is the third release withupdated contents.The purpose of this document isto inform designers and project engineers aboutthe most important mechanical standards oftheglobally developed and approved IEC standards ina very condensed manner. Users are encouragedto look up more detailed information on IEC's Website or in other printed sources.3Michael ThompsonUSAPrincipal EngineerPaul MazuraGermanyVice President ProductDevelopment andStandardizationAkio ShimadaJapanManager MarketingandStandardizationKeith ReynoldsUKTechnical ManagerThe Schroff commitment to standardsSince 1978 Schroff is activ...
