Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directives

AMENDMENT 1: Conformance test assertions
Page 1, Clause 1
Add the following text to the existing Scope:
“This part of ISO/IEC 19794 also specifies elements of conformance testing methodology, test assertions,
and test procedures as applicable to this part of ISO/IEC 19794. It establishes test assertions pertaining
to the structure of the signature/sign processed dynamic data format (Type A Level 1 as defined in
ISO/IEC 19794-1X AMD 1), test assertions pertaining to internal consistency of the types of values that
may be contained within each field (Type A Level 2 as defined in ISO/IEC 19794-1X AMD 1), and semantic
test assertions (Type A Level 3 as defined in ISO/IEC 19794-1X AMD 1).
The conformance testing methodology specified in this part of ISO/IEC 19794 does not establish:
• 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 data records conforming to the requirements
of this part of ISO/IEC 19794.”
Page 1, Clause 2
Add the following text to the existing “Conformance” clause:
“Biometric data interchange format conformance tests conform to this part of ISO/IEC 19794 if they
satisfy all of the normative requirements set forth in clauses X, Y, and Z. Specifically, they shall use the
test methodology specified in Clauses A, B, and C of ISO/IEC 19794-1x AMD 2, and all Level 1, Level 2 and
Level 3 tests shall use the assertions defined in Table N of Clause M in this part of ISO/IEC 19794.
Implementations of this part of ISO/IEC 19794 tested according to the specified methodology shall be
able to claim conformance only to those biometric data record (BDB) requirements specified in this part
of ISO/IEC 19794 that are tested by the test methods established by this methodology.
Implementations of this part of ISO/IEC 19794 do not necessarily need to conform to all possible aspects
of this part of ISO/IEC 19794, but only to those requirements that are claimed to be supported by the
implementation in an implementation conformance statement (ICS), filled out in accordance with
Clause K of ISO/IEC 19794-1x AMD 1 and Table K of Clause R of this part of ISO/IEC 19794.”

Annex A
(normative)
Conformance test assertions
A.1 Introduction
This normative annex specifies elements of conformance testing methodology, test assertions, and test
procedures as applicable to signature/sign processed dynamic data.
The normative annex establishes
— conformance test assertions on the structure and internal consistency of signature/sign processed
dynamic data as specified in this part of ISO/IEC 19794 (Type A Level 1 and Level 2 as defined in
ISO/IEC 19794-1X AMD 1),
— semantic conformance test assertions on signature/sign processed dynamic data as specified in
this part of ISO/IEC 19794.
This normative annex does not establish
— conformance test assertions on CBEFF structures embedding signature/sign processed dynamic
data,
— test assertions on other characteristics of biometric products (e.g. acceptance, performance,
robustness, security),
— conformance test assertions on systems that do not produce signature/sign processed dynamic
data as specified in this part of ISO/IEC 19794.
The conformance testing methodology specified in ISO/IEC 19794-1X AMD 1 shall apply. The content
of the tables below is based on ISO/IEC 19794-1X AMD 1 and shall only be used in the context of that
conformance testing methodology.
The conformance test assertions are listed in the order in which the corresponding fields are required
to appear, if present, in a conforming record.
A.2 Table of requirements
The normative requirements of this part of ISO/IEC 19794 are listed in the Table A.1. The supplier of the
IUT shall explain which optional components of the standard are supported and the testing laboratory
shall note the results of the test.
