1、Designation: F3153 15Standard Specification forVerification of Avionics Systems1This standard is issued under the fixed designation F3153; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in paren
2、theses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification provides a process by which theintended function and compliance with safety objectives ofavionics systems may be verified by system
3、-level testing.1.2 Software and hardware development assurance are notin the scope of this specification and this specification shouldnot be used if a development assurance process is required.1.3 The specification intentionally does not attempt todefine its own applicability with regard to the type
4、, category,class of aircraft, or criticality of function to which avionicssystems verified by the specification may be applied as doingso could ultimately place the language of the specification inconflict with external requirements and guidance. Aircraftapplicability, intended use, and limitations
5、must ultimately bedetermined by the designer, installer, and recognizing body.1.4 This verification process specifically addressesdefinition, identification, and verification of system functions.Processes conducted under this specification may not satisfy allapplicable external requirements; additio
6、nal review on the partof the system developer, integrator, or installer may be requiredto meet specific requirements or the specified mission of theaircraft, or both.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of t
7、he user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

United States15.3 Function Specification:5.3.1 For each function identified for verification under thisspecification in 5.2, document the specifications of thefunction, including:5.
17、3.1.1 A description of the function,5.3.1.2 An explanation of the intended use of the function,and5.3.1.3 Operating parameters or limitations that apply to thefunction.NOTE 2The requirements of 5.1 and 5.3 may be met by a suitablyannotated copy of the systems user or installation manual or by means
18、ofreference to a third-party specification (such as a TSO minimum perfor-mance standard).6. Verification Process6.1 Functional Verification Planning:6.1.1 Document the system test plan.6.1.2 For each function identified for verification under thisspecification in 5.2:6.1.2.1 Define a series of test
19、scenarios and pass/fail criteriathat trace to the functional requirement and that verify thefunctions correct operation within the set limits. In developingthe test scenarios, consider known failures in similar systemsor components, or both.6.1.2.2 The test scenario should include failure conditions
20、when appropriate and important to the system level function.NOTE 3Where applicable, make use of a functional, non-functional,ground, and flight tests, providing direct reference to the specificationsdocumented in 5.3 that make this specific test necessary.6.2 Testing:6.2.1 Execute the previously def
21、ined test scenarios.6.2.2 Review test results and document pass/fail for eachtest scenario.6.3 Test Failure Resolution:6.3.1 Resolve all test failures via one or more of thefollowing means:6.3.1.1 Revision to the system or its specifications,6.3.1.2 Revision of the system test plan,6.3.1.3 Justifica
22、tion for deferral to a future revision.6.3.2 Identify the test(s) to be re-executed to verify therevised version of the system.6.4 Regression Analysis and Testing:6.4.1 Changes to the system or intended installation whichcould affect any function verified under this specificationshould be re-verifie
23、d at such times that those changes are made.An analysis should be conducted to determine which functionsrequire re-verification based on the design of the system and itsintegration into the aircraft.7. Verification Document7.1 Produce a Statement of Verification that includes:7.1.1 The name of the s
24、ystem;7.1.2 The revision indicators (version numbers) for thesystem component(s) tested;7.1.3 A list of functions verified under this specification;7.1.4 A list of functions verified by other means;NOTE 4Whether and how these other means must be identified is outof scope of this specification.7.1.5
25、The date upon which the verification was successfullycompleted;7.1.5.1 The following statement: “The listed functions ofthe system have been tested and verified to operate in accor-dance with the functional and performance characteristicsoutlined in the system documentation. Testing has been con-duc
26、ted following the process defined in ASTM SpecificationF3153.”ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentionedin this standard.
