The work of preparing International Standards is normally carried out through IsO International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization International Standards are drafted in accordance with the rules given in the ISO/lEC Directives, Part 2 The main task of technical committees is to prepare International Standards. Draft International Standards International Standard requires approval by at least 75 % of the member bodies casting a vote.

IV @ ISO 2005 - All rights reserved ISO 14954:2005(E) INTERNATIONAL STANDARD Space systems Dynamic and static analysis Exchange of mathematical models Scope This International Standard normalizes the exchange of mathematical models between payload contractors (PLC) and launch service providers (LSP). It identifies standard methods for modelling the dynamic behaviour of both launch vehicles (LV) and payload (PL), particularly when they are coupled prior to launch and during the early moments of the launch phase. In standardmode,thedelivered modelsrepresentdynamicand staticbehaviouratthe launcher interface.The requirements provided in this International Standard are the minimum necessary for dynamic coupled analysis. They may not be sufficient for stress analysis. The payload models are full integrated models from the different parts of the payload under the payload contractor authority, including also their own adapter to LV interfaceinthecasethattheadapterisapartofthepayload This
