ISO 16290:2013 pdf download.Space systems一Definition of the Technology Readiness Levels (TRLs) and their criteria of assessment.
ISO 16290 defines Technology Readiness Levels (TRLs). It is applicable primarily to space system hardware, although the definitions 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 definitions
For the purposes of this document, the following terms and definitions apply.
2.1
breadboard
physical model (2.10) designed to test functionality and tailored to the demonstration need
2.2
critical function of an element
mandatory function which requires specific technology (2.19) verification
Note ito entry: This situation occurs when either the element or components of the element are new and cannot be assessed by relying 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 should 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”.
2.3
critical part of an element
element (2.4) part associated to a critical function
Note 1 to entry: The critical part ofan 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 critical part”.
Note 3 to entry: Wherever used in this International Standard, “critical part” always refers to “critical part of an element”.
2.4
element
item or object under consideration for the technology readiness assessment
Note I to entry: The element can be a component, a piece of equipment, a subsystem or a system.
2.5
element function
intended effect of the element (2.4)
2.6
functional performance requirements
subset of the performance requirements (2.14) of an element (2.4) specifying the elementfunctions (2.5)
Note 1 to entry: The functional performance requirements do not necessarily include requirements resulting from the operational environment (2.11).
2.7
laboratory environment
controlled environment needed for demonstrating the underlying principles and functional performance
Note 1 to entry: The laboratory environment does not necessarily address the operational environment (211).
2.8
mature technology
technology defined by a set of reproducible processes (2.17) for the design, manufacture, test and operation ofan element(2.4) for meeting a set of performance requirements (2.14) in the actual operational environment (2.11)
2.9
mission operations
sequence of events that are defined for accomplishing the mission.ISO 16290 pdf download.
