This specification describes a process for verifying the intended function and compliance with safety objectives of avionics systems by means of system-level testing. This verification process includes functional verification planning, testing, resolution of test failures, and regression analysis and testing. It also covers organizational requirements and the process of product definition (function identification, classification, and specification) as well as the requirements for producing a statement of verification.

1.1 This specification provides a process by which the intended function and compliance with safety objectives of avionics systems may be verified by system-level testing.

1.2 Software and hardware development assurance are not in the scope of this specification and this specification should not be used if a development assurance process is required.

1.3 The specification intentionally does not attempt to define its own applicability with regard to the type, category, class of aircraft, or criticality of function to which avionics systems verified by the specification may be applied as doing so could ultimately place the language of the specification in conflict with external requirements and guidance. Aircraft applicability, intended use, and limitations must ultimately be determined by the designer, installer, and recognizing body.

1.4 This verification process specifically addresses definition, identification, and verification of system functions. Processes conducted under this specification may not satisfy all applicable external requirements; additional review on the part of the system developer, integrator, or installer may be required to meet specific requirements or the specified mission of the aircraft, or both.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
