(Main)Space engineering - Testing guidelines
Space engineering - Testing guidelines
This handbook provides additional information for the application of the Testing standard EN 16603-10-03.
This handbook will be the guideline for all space projects, related equipment and complete systems, by providing background information that aids the reader to better understand and meet the requirements of the standard.
The document would follow the flow of the Testing standard and in particular w hatever is excluded from the testing standard (see Scope of EN 16603-10-03) should also be excluded.
NOTE: EN 16603-10-03:2014 will be in parallel also updated to take into account the new TR.

Vesoljska tehnika - Smernice za preskušanje
Ta priročnik vsebuje dodatne informacije za uporabo standarda za preskušanje EN 16603-10-03.
Uporabljal se bo kot smernica za vse vesoljske projekte, povezano opremo in celovite sisteme, saj zagotavlja osnovne informacije, ki bodo bralcu pomagale bolje razumeti in izpolnjevati zahteve standarda.
Ta dokument bi moral slediti strukturi standarda za preskušanje, zlasti pa je iz njega priporočljivo izključiti vse, kar je izključeno tudi iz standarda za preskušanje (glej področje uporabe standarda EN 16603-10-03).
OPOMBA: Standard EN 16603-10-03:2014 se bo tudi sproti posodabljal tako, da bo v njem upoštevano novo tehnično poročilo (TR).
