(Main)Space engineering - Fracture control
Space engineering - Fracture control
This ECSS Engineering Standard specifies the fracture control requirements to be imposed on space segments of space systems and their related GSE.
The fracture control programme is applicable for space systems and related GSE when required by ECSS-Q-ST-40 or by the NASA document NST 1700.7, incl. ISS addendum.
The requirements contained in this Standard, when implemented, also satisfy the fracture control requirements applicable to the NASA STS and ISS as specified in the NASA document NSTS 1700.7 (incl. the ISS Addendum).
The NASA nomenclature differs in some cases from that used by ECSS. When STS/ISS-specific requirements and nomenclature are included, they are identified as such.
This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.

Vesoljska tehnika - Kontrola razpok
Ta tehnični standard ECSS določa zahteve za kontrolo razpok, ki se izvaja na vesoljskih delih vesoljskih sistemov in njihovih povezanih GSE. Program za kontrolo razpok velja za vesoljske sisteme in z njimi povezane GSE, če to zahteva standard ECSS-Q-ST-40 ali Nasin dokument NST 1700.7, vklj. z dodatkom ISS. Ko se izvajajo zahteve iz tega standarda, te izpolnjujejo tudi zahteve za kontrolo razpok, ki veljajo za NASA STS in ISS, kot je določeno v Nasinem dokumentu NSTS 1700.7 (vklj. z dodatkom ISS). Nasina nomenklatura se v nekaterih primerih razlikuje od tiste, uporabljene pri ECSS. Ko so vključene zahteve, določene s STS/ISS, in nomenklatura, so prepoznane kot take. Ta standard se lahko prilagodi posameznim lastnostim in omejitvam vesoljskega projekta v skladu s standardom ECSS-S-ST-00.
