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. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. IsO shall not be held responsible for identifying any or all such patent rights. ISO 10786 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 14, Space systems and operations.

Currently, there is no International Standard that covers all the aspects that can be used for spaceflight structuralitemssuchasspacecraftplatforms,interstageadaptors,launchvehiclebusesandrocketmotor cases. The purpose of this International Standard is to establish general requirements for structures. It provides the uniform requirements necessary to minimize the duplication o
