Th

19、is standard (EN 16603-10-06:2014) originates from ECSS-E-ST-10-06C. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2015, and conflicting national standards shall be withdrawn at the late

20、st by February 2015. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document will supersede EN ISO 21351:2005. This document has

21、 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 specifically space systems and has therefore precedence over any EN covering the same scope but with a wider domain of applicability (e.g. : aeros

22、pace). According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, Fran

24、sses the process for and the content of the Technical requirements specification (TS). This document is an adaptation of ISO 21351 “Space systems Functional and technical specifications” to the ECSS context. BS EN 16603-10-06:2014EN 16603-10-06:2014 (E) 6 1 Scope This Standard provides an overview o

25、f the purposes and positions of the technical requirements specification, defines the different types of requirements, and defines requirements on the TS and on its requirements. This Standard is applicable to all types of space systems, all product elements, and projects. This standard may be tailo

26、red for the specific characteristic and constraints of a space project in conformance with ECSS-S-ST-00.

27、SS Standard. For dated references, subsequent amendments to, or revision of any of these publications, do not apply. However, parties to agreements based on this ECSS Standard are encouraged to investigate the possibility of applying the more recent editions of the normative documents indicated belo

28、w. For undated references, the latest edition of the publication referred to applies.

29、s, definitions and abbreviated terms 3.1 Terms from other standards For the purposes of this Standard, the terms and definitions from ECSS-S-ST-00-01 apply. 3.2 Terms specific to the present standard3.2.1 constraint characteristic, result or design feature which is made compulsory or has been prohib

30、ited for any reason NOTE 1 Constraints are generally restrictions on the choice of solutions in a system. NOTE 2 Two kinds of constraints are considered, those which concern solutions, and those which concern the use of the system. NOTE 3 For example constraints can come from environmental and opera

31、tional conditions, law, standards, market demand, investments and means availability, or the organizations policy. NOTE 4 Adapted from EN 1325-1. 3.2.2 environment natural conditions and induced conditions that constrain the design definitions for end products and their enabling products NOTE Exampl

32、es of natural conditions are weather, climate, ocean conditions, terrain, vegetation, dust, light and radiation. Example of induced conditions are electromagnetic interference, heat, vibration, pollution and contamination. 3.2.3 environment external factors affecting an enterprise or project 3.2.4 e

33、nvironment external factors affecting development tools, methods, or processes BS EN 16603-10-06:2014EN 16603-10-06:2014 (E) 9 3.2.5 function intended effect of a system, subsystem, product or part NOTE 1 Adapted from EN 1325-1. NOTE 2 Functions should have a single definite purpose. Function names

34、should have a declarative structure (e.g. “Validate Telecommands”), and say “what” is to be done rather than “how”. Good naming allows design components with strong cohesion to be easily derived. 3.2.6 functional analysis technique of identifying and describing all functions of a system NOTE Adapted

35、 from EN 1325-1. 3.2.7 life cycle time interval between the conceptual exploration of the product introduction to its withdrawal from service 3.2.8 mission a possible instantiation of the mission statement in a mission concept NOTE 1 Each mission is described in an MDD. NOTE 2 The implementation in

36、time is called mission scenario. 3.2.9 need what is necessary for, or desired by, the user NOTE 1 A need can be declared or undeclared; it can be an existing or a potential one. NOTE 2 The user is a person or an organization for which the product is designed and which exploits at least one of its fu

37、nctions at any time during its life cycle. NOTE 3 For the space community, the needs are often called mission statement. NOTE 4 Adapted from EN 1325-1. 3.2.10 specification document stating requirements NOTE 1 A specification can be related to activities (e.g. procedure document, process specificati

38、on and test specification), or products (e.g. technical requirements specification) NOTE 2 Adapted from ISO 9000:2000. BS EN 16603-10-06:2014EN 16603-10-06:2014 (E) 10 3.2.11 technical requirements specification document by which the customer establishes the intended purpose of a product, its associ

39、ated constraints and environment, the operational and performances features NOTE The TS is the baseline of the business agreement to develop or purchase the selected solution. This specification is called in some projects System Requirements Document (SRD). 3.3 Abbreviated terms For the purpose of t

40、his Standard, the abbreviated terms from ECSS-S-ST-00-01 and the following apply: Abbreviation Meaning IEC International Electrotechnical Commission TS technical requirements specification MDD mission definition documentBS EN 16603-10-06:2014EN 16603-10-06:2014 (E) 11 4 Technical requirements specif

41、ication purpose and description 4.1 Technical requirements specification purpose and description The technical requirements specification is a document through which a customer expresses his needs (or those that he is responsible for expressing) and the related environment and constraints in terms o

42、f technical requirements. The technical requirements contained in the TS allow for potential suppliers to propose the best technical and programmatic solutions. NOTE The intention of the technical requirements specification is not to assume or refer to specific solutions. The TS is the technical ref

43、erence for the qualification of the design and for the acceptance of the end product. In that scope, the technical requirements contained in the TS are subject to the agreed change process defined in the business agreement. They are attainable and verifiable. NOTE The change process itself can chang

44、e in between project phases (Phase 0, A, B, C/D). 4.2 TS content A technical requirements specification is typically composed of three major sets of information: General information related to the context of the document (e.g. administrative information, normative documents and informative documents

45、); General information related to the context of the project, the product or system; Technical requirements (described in clauses 6 and 8). BS EN 16603-10-06:2014EN 16603-10-06:2014 (E) 12 The specification provides the general information related to its context: Administrative information: to provi

46、de all the information regarding, for example, the owner, status, identification, distribution list, and management rule; Scope: to define without ambiguity the subject of the TS and aspects covered, thereby indicating limits of applicability; References: to list all the normative (applicable) docum

47、ents and standards, with titles, issue revision, and dates that are referred to in the TS; Terms, definitions and abbreviated terms: to list the specific terms and abbreviated terms used in the TS. It also provides general information related to the context of the project, product or system: to prov

48、ide a clear and rapid understanding of the project and the main needs or mission statements; to give indications of the market as additional information, as well as information about the context of the project and the objectives (situation of the project in a larger programme, further developments);

49、 to provide information on the environment and its constraints; to detail the different situations of the product or system life cycle. BS EN 16603-10-06:2014EN 16603-10-06:2014 (E) 13 5 Process for establishing a technical requirements specification 5.1 General The management of a programme necessitates the establishment of a set of successive states of a product and a network of customer and supplier relationships. The successive states of a product are characterised by initially a “high level” (e.g. rather of functional type) definition of needs / r
