This part of ISO/IEC 29109 specifies elements of conformance testing methodology, test assertions, and test procedures as applicable to ISO/IEC 19794-4. It establishes — test assertions of the structure of the finger image data format as specified in ISO/IEC 19794-4:2005 (Type A Level 1 as defined in ISO/IEC 29109-1:2009), — test asssertions of internal consistency by checking the types of values that may be contained within each field (Type A Level 2 as defined in ISO/IEC 29109-1:2009), — tests of semantic assertions (Type A Level 3 as defined in ISO/IEC 29109-1:2009). It does not establish — tests of conformance of CBEFF structures required by ISO/IEC 19794-4:2005, — tests of other characteristics of biometric products or other types of testing of biometric products (e.g. acceptance, performance, robustness, security), — tests of conformance of systems that do not produce ISO/IEC 19794-4:2005 records.
