Designation:F315315Standard 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 parentheses 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-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,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 must ultimately bedetermined by the designer,installer,and recognizing body.1.4 Thisverificationprocessspecificallyaddressesdefinition,identification,and verification of system functions.Processes conducted under this specification may not satisfy allapplicable external requirements;additional 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 the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2F3060 Terminology for Aircraft3.Terminology3.1 The following are a selection of relevant terms.SeeTerminology F3060 for more definitions and abbreviations.3.2 Definitions:3.2.1 defect,nan unexpected or improper behavior.3.2.2 intended function,na capability the system is de-signed to provide when installed on an aircraft.3.2.3 system,na combination of components,parts,andelements that are interconnected to perform one or morefunctions.3.2.4 test scenario,na set of inputs,pre-conditions,ex-ecution steps,expected results,and pass/fail crtieria defined bythe manufacturer to verify proper function.Test scenarios arederived from the intended functions established for the system.3.2.5 verification,nconfirmation,through the collectionand review of objective evidence,that specified requirementshave been fulfilled.4.Organizational Requirements4.1 An organization complying with this specification shallmanage under configuration control all life cycle data whichare generated by applying this specification.4.2 The organization shall keep a record of the documenta-tion used to show compliance of each approved systemconfiguration produced to all applicable consensus specifica-tions and regulatory requirements in effect at the time ofmanufacture.4.3 Revisions to documentation affecting compliance shallbe tracked and the change process for developing,reviewing,and incorporating revisions to compliance documentation shallbe controlled.4.4 The organization must ensure and verify the use of theproper revision of any compliance document.5.Product Definition Process5.1 Function Identification:5.1.1 Document the intended function(s)of the system.5.2 Function Classification:5.2.1 For each function identified under 5.1,determine anddocument whether it is to be verified under this specification orby other means.NOTE1Other means of verification may be proprietary or may bebased on other standards,as best suits the developers objectives withregard to safety,marketability,and compliance concerns.1This specification is under the jurisdiction ofASTM Committee F39 on AircraftSystems and is the direct responsibility of Subcommittee F39.03 on Design ofAvionics Systems.Current edition approved July 15,2015.Published September 2015.DOI:10.1520/F3153-15.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.3 Function Specification:5.3.1 For each function identified for verification under thisspecification in 5.2,document the specifications of thefunction,including:5.3.1.1 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.NOTE2The requirements of 5.1 and 5.3 may be met by a suitablyannotated copy of the systems user or ins
