11、on for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing 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 ha

12、s the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The p

13、rocedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the edit

17、o be used in a mission. Mature technology corresponds to the highest TRL, namely TRL 9, or flight proven elements.The TRL scale can be useful in many areas including, but not limited to the following examples:a) For early monitoring of basic or specific technology developments serving a given future

18、 mission or a family of future missions;b) For providing a status on the technical readiness of a future project, as input to the project implementation decision process;c) In some cases, for monitoring the technology progress throughout development.The TRL descriptions are provided in Clause 3 of t

19、his International Standard. The achievements that are requested for enabling the TRL assessment at each level are identified in the summary table in Clause 4. The detailed procedure for the TRL assessment is to be defined by the relevant organization or institute in charge of the activity.This Inter

20、national Standard was produced by taking due consideration of previous available documents on the subject, in particular including those from the National Aeronautics Space Administration (NASA), the US Department of Defence (DoD) and European space institutions (DLR, CNES and ESA).

It is applicable primarily to space system hardware, although the definiti

22、ons could be used in a wider domain in many cases.The definition of the TRLs provides the conditions to be met at each level, enabling accurate TRL assessment.2 Terms and definitionsFor the purposes of this document, the following terms and definitions apply.2.1breadboardphysical model (2.10) design

24、ing on previous realizations, or when the element is used in a new domain, such as new environmental conditions or a new specific use not previously demonstrated.Note 2 to entry: Wherever used in this International Standard, “critical function” always refers to “technology critical function” and sho

25、uld not be confused with “safety critical function”.Note 3 to entry: Wherever used in this International Standard, “critical function” always refers to “critical function of an element”.2.3critical part of an elementelement (2.4) part associated to a critical functionNote 1 to entry: The critical pa

26、rt of an element can represent a subset of the element and the technology verification for the critical function may be achievable through dedicated tests achieved on the critical part only.Note 2 to entry: Wherever used in this International Standard, “critical part” always refers to “technology cr

A technology can be declared mature at a given time, and degraded later at a lower readiness level because of the obsolescence of its components or because
