This standard (EN 16602-20-10:2014) originates from ECSS-Q-ST-20-10C. This European Standard shall be g
17、iven the status of a national standard, either by publication of an identical text or by endorsement, at the latest by March 2015, and conflicting national standards shall be withdrawn at the latest by March 2015. Attention is drawn to the possibility that some of the elements of this document may b
18、e the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. This document has been developed to cover s
19、pecifically space systems and has therefore precedence over any EN covering the same scope but with a wider domain of applicability (e.g. : aerospace). According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this Europ
20、ean Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slov

BS EN 16602-20-10:2014EN 16602-20-10:2014 (E) 5 1 Scope This Standard applies to all parties involved at all levels in the utilization of OTS items into space segment hardware and launchers. For the purpose of this Standard, Off-the-Sh
22、elf (OTS) Items are those that, even if not necessarily developed for space applications, can be procured from the market and utilized in a space system. This Standard contains the requirements for the utilization of OTS Items, in terms of their selection, characterization and procurement for space
23、system use. This Standard considers complex OTS items, as for example: motherboards, cards, data storage units/items, optical equipments, photo cameras and video units, LANs, mechanical/electrical and electromechanical devices, batteries, sensors, monitoring support units, medical equipments and ite
24、ms, laptops. This Standard does not cover: software OTS, re-use of OTS items already qualified for space applications, NOTE However, items not belonging to the same lot of the OTS item already evaluated using this standard, can be subjected to partial re-evaluation and re-qualification since, on the
25、 commercial market, fast evolution of the design occurs. Pieces, parts and materials, such as electrical, electronic and electromechanical (EEE) parts, thermocouples, rivets, fasteners, connectors, fittings, adhesives, insulation, wiring and plumbing. This standard is not specifically addressing the
26、 re-use of OTS items for the same space application for which they were initially qualified. This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.

39、iminary equipment specification be issued. In parallel to this an OTS Plan is prepared. At this point, the relevant market survey can be started. For each OTS item candidate an evaluation dossier is initiated and all these OTS item candidates are compared to the project requirements in order to have
40、 a preliminary make or buy decision. As an input to the System SRR, a preliminary OTS make/buy decision milestone identifies a restricted number (maximum three) of OTS item candidates for which the buy approach is viable. Refer to Figure 4-1 first sector. NOTE The liability for introducing an OTS It
41、em into the Project remains always with the design authority which is in charge of the make-or-buy decision. 4.1.2 OTS item characterization and selection After the System SRR, the updated equipment specification and OTS Plan is used as input to the characterization of each OTS item candidate. Durin
42、g the characterization the OTS item candidates are deeply investigated in order to assess their performance and qualification status and to identify any possible modification to be introduced in the OTS item or in the system hosting it and any delta qualification activity. The OTS item evaluation do
43、ssiers are incrementally updated to reflect the results of these investigations; at the end the best suitable OTS item candidate is selected, and all related modifications and delta qualification activities are identified thus confirming that the OTS item is qualifiable. The OTS item evaluation doss
44、ier of the selected candidate, together with the equipment specification and the OTS Plan, both updated for PDR, are used to support the final make-or-buy decision milestone at the System PDR. Refer to Figure 4-1 second sector. BS EN 16602-20-10:2014EN 16602-20-10:2014 (E) 10 4.1.3 OTS item procurem
45、ent and qualification After the final make-or-buy decision milestone at the System PDR, if the “Buy“ decision has been taken, the procurement activities can start. Since this ECSS is not dealing with the simple re-procurement of already space qualified OTS Items, two options for procurement can be e
46、nvisaged: OTS Items for qualification and OTS Items for flight are procured at different times; Both OTS Items for qualification and for flight are procured at the same time. The supplier selects which option is the best based on the relevant Project programmatic needs. Regardless of the procurement
47、 option selected, the Supplier then performs the necessary qualification and acceptance related activities as per the Project applicable requirements, detailed inside the OTS plan and the equipment specification. The qualification phase ends when the selected OTS Item has reached the Qualification s
48、tatus requested by the Project. The output of this phase is the completed OTS Item Evaluation Dossier that is used to support the OTS Item Qualification status assessment. Procurement of flight units, when the flight hardware is procured separately from the one used for qualification, is then initia
