AAT ICAS quality resources


quality in terms of conformance

questions about the relative conformance of an ICAS method or application to an ICAS standard may be considered with regard to the use or function of a feature or system with regard to any conditions bearing on its scope of use. the guidelines below may be used to test or determine the relative conformance of a particular feature or system to an ICAS standard. validity of a determination may be based on the extent to which any test measure indicates a corresponding factor or function, and the extent to which a test finding may be generalized to situations other than the test.


AAT ICAS quality guidelines

AAT ICAS quality guidelines may be applied to determine the conformance of a use or application of ICAS with an effective AAT ICAS standard. a determination of conformance with one or more guidelines does not necessarily constitute conformance with an AAT ICAS standard. AAT ICAS quality guidelines are not a substitute for other applicable guidelines. guidelines are subject to change.
