The work of preparing

14、International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaiso

15、n with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of tec

16、hnical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is dra

17、wn 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 14621-2 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 14, Space sys

18、tems and operations. ISO 14621 consists of the following parts, under the general title Space systems Electrical, electronic and electromechanical (EEE) parts: Part 1: Parts management Part 2: Control programme requirements BSISO146212:2003. vi BSISO146212:2003ANRETNIITOTS LANDNADRA OSI -126413002:2

19、)E( ISO 3002 r llAithgs reservde 1 Space systems Electrical, electronic and electromechanical (EEE) parts Part 2: Control programme requirements 1S c o p e This part of ISO 14621 establishes technical guidelines for developing and documenting an electrical, electronic and electromechanical (EEE) par

These guidelines are tailorable to the needs of each individual programme based on the project

21、performance criteria, risk tolerance, budget, mission duration, environment, schedule and other considerations. This part of ISO 14621 is applicable to all customers and suppliers furnishing flight hardware and is suitable for reference in proposal instructions. 2 Normative references The following

29、ng clauses. The customer and suppliers may include additional tasks not described below, and exclude tasks described herein based on other factors such as project design implementation, and the projects risk tolerance, in order to institute the most effective parts control programme for the space sy

30、stem. The customer should reference this part of ISO 14621 in the request for proposal or statement of work and should identify any additional tasks, deletions, or other special requirements with regard to parts. The supplier BSISO146212:20032OSI -126413002:2)E( ISO 3002 r llAithgs reservde 3 shall

31、implement a parts control programme covering each of the subjects in 5.2 to 5.20 and any additional tasks included in the request for proposal or statement of work. If any of these tasks are excluded, they should be so identified. 5.2 Organization The space hardware supplier shall identify the organ

32、ization responsible for managing its parts control programme and describe the organizations approaches, skills, and authority to implement, manage, and control the parts control programme efficiently, including reporting, as specified in ISO 14300-1. 5.3 Parts selection and standardization The space

33、 hardware supplier shall have an EEE parts selection and standardization process and implementation plan, which will allow it to meet the cost, schedule, operating, stability, environmental, radiation, material, safety, quality and reliability requirements defined for the related space programme, as

34、 described in ISO 14300-1 and ISO 14300-2. The space hardware supplier shall describe the process for selection and standardization of the parts as defined in ISO 14621-1. This includes the approach for technology insertion and the methodology and rationale for selection of parts manufacturers and s

35、ervice companies. The space hardware supplier shall optimize the use of previously qualified or approved parts for equivalent applications, thereby restricting the number of different part types, encouraging standardization and reducing life cycle costs and risk of obsolescence. The supplier is reco

36、mmended to have a preferred parts list (PPL), a parts usage list or an equivalent approved parts list which includes parts suitable from the viewpoint of quality assurance, cost availability, usage history, new and current technology, and data to support their space radiation sensitivity. 5.4 Parts

37、evaluation and characterization The space hardware supplier shall define the process to be implemented for the evaluation and characterization of the EEE parts. Where adequate assessment data does not already exist, the space hardware supplier shall define and describe how it will verify the capabil

38、ity of each selected part type to meet the mission requirements, in accordance with ISO 14621-1. The manufacturer or service company used by the space hardware supplier shall be capable of demonstrating that they meet the performance requirements and expectations of the programme. This includes a de

39、scription of the configuration controls that ensure that the parts used for space hardware are equivalent in form, fit, function and performance to the evaluated parts. 5.5 Parts requiring specific authorization Prior to incorporating EEE parts into any space hardware, the supplier shall develop a r

40、isk management plan (see 5.18) for EEE parts requiring specific authorization or restriction for reasons such as limited-life, limited useful shelf life, instability, operation outside temperature range, or other reliability risks. The supplier shall address the methodology used for custom and in-ho

41、use developed parts. These parts shall be subjected to the same evaluation criteria as all other parts. 5.6 Radiation hardness assurance programme The space hardware supplier shall define the development and implementation of a EEE parts radiation hardness assurance (RHA) programme addressing all ap

42、plicable phases of the programme emphasizing the early development phase, such as system design radiation impact analysis, technical parts review, RHA test programme design, radiation evaluation testing and RHA impact reporting. BSISO146212:20033ISO -12641:2)E(3002 4 ISO 3002 All rithgs reresvde The

43、 space hardware supplier shall document how the part types shall be reviewed to establish their sensitivity to all radiation effects, the manner in which these effects are determined, whether there is a necessity for system mitigation techniques and, if so, how they will be implemented. 5.7 Parts de

44、rating The space hardware supplier shall document a process for derating all EEE parts, for all factors that degrade performance in order that the parts are capable of meeting probability of mission success and mission life requirements. Furthermore, the space hardware supplier shall verify derating

45、 conformance by analysis or test (parts stress analysis) in accordance with ISO 14621-1. 5.8 Parts approval process The space hardware supplier shall document the process for approval of each part before installation into space hardware and provide access to the part selection process, including ris

46、k assessment, before design acceptance sign-off, in accordance with the delegation level defined by the customer. 5.9 Parts procurement documents The space hardware supplier shall describe the process for originating the necessary procurement specifications and using existing specifications, such as

47、 controlled specifications, drawings, CIDs, or standard manufacturer part numbers for the procurement of parts. 5.10 Parts screening The space hardware supplier shall describe how all parts used in space hardware are to be screened to the extent appropriate for the space programme. The screening tes

48、t requirements shall be designed so that accumulated stresses do not jeopardize parts reliability. The relevant screening process shall be defined by the supplier and shall be available as input to the reliability programme. 5.11 Lot acceptance test (LAT)/quality conformance inspection (QCI)/technol

49、ogy conformance inspection (TCI) Based on the available technical performance and parts manufacturers test data, the procurement responsible shall apply the LAT/QCI/TCI rules defined by the space hardware supplier and, when necessary, shall select the appropriate level of LAT/QCI/TCI, in accordance with the space hardware suppliers requirements, to demonstrate that each lot is in accordance with the technical and
