ISO/IEC 10641:1993

Information technology — Computer graphics and image processing — Conformance testing of implementations of graphics standards

Specifies a general framework addressing the following six components: conformance in the standard itself; test requirements document (defining what shall be tested for a computer graphics standard); test specifications document (addressing the test technique and the content of each test); test method (defining the implementation of the test specification document, including the test software); test procedures (defining the application of the test software, which consists of the procedures to be used in conformance testing); the establishment of test services. Is applicable to all standards within the scope of the ISO/IEC JTC1 subcommittee responsible for computer graphics and image processing.

Foreword
IS0 (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form
the specialized system for worldwide standardization. National bodies that are members of IS0 or IEC participate in the
development of International Standards through technical committees established by the respective organization to deal
with particular fields of technical activity. IS0 and IEC technical committees collaborate in fields of mutual interest.
Other international organizations, governmental and non-governmental, in liaison with IS0 and IEC, also take part in the
work.
In the field of information technology, IS0 and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft
International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication
as an International Standard requires approval by at least 75 % of the national bodies casting a vote.
International Standard ISO/IEC 10641 was prepared by Joint Technical Committee ISOLIEC JTC 1, Information tech-
nology, Sub-Committee SC 24, Computer graphics and image processing.
Annexes A and B of this International Standard are for information only.

Introduction
This International S tandard addresses conform nance testing of implementations of graphics stand‘ards. Conformance testing is
the method used to
determine the adherence or non-adherence of an implementation under test (WI’) to a staklard.
This International Standard specifies an approach for St2 ndards of products that
testing the conformance to computer graphics
claim to implement these standards. It addresses the conformance testing processes for all classes of graphics standards
This International Standard defirtes a general framework of procedures and guidelines for conformance testing, together with
definitions of terms and concepts.
The framework given in this International Standard, together with the Test Requirements document for a particular graphics
standard, provides a description of the procedures to be followed to achieve successful conformance testing of products for
conformance to a particular graphics standard.
The concept of conformance is central to every standard. The aims and benefits of a standard can be realized if there is a
means of testing for conformance.
The main reasons for introducing a document on conformance testing in the area of computer graphics are:
- To promote standards that are developed in a way such that products can be tested for conformance to the standards’
requirements;
- To promote that conformance is addressed in each standard;
- To promote test suites that are appropriately defined for testing products for conformance to all areas of the
standard, and are of high quality;
- To promote test methods for similar standards that are developed in a consistent way;
- To promote conformance testing that is carried out in a consistent way throughout the international graphics
community.
Users of this International Standard include:
- Developers of graphics standards;
- Implementors of graphics standards;
- Developers of graphics test suites;
- Testing laboratories;
- Certification bodies;
- Accreditation bodies.
Annexes A and B contain diagrams illustrating the relationships among the users of this International Standard and the
information shared by them.

Scope
This International Standard specifies a general framework for testing conformance to a computer graphics standard. The general
framework described in this International Standard addresses the following six components:
- Conformance in the standard itselfr
- Test Requirements document, defining what shall be tested for a computer graphics standard;
- Test Specifications document, addressing the test technique and the content of each test
- Test method, defining the implementation of the Test Specification document, including the test software;
- Test procedures, defining the application of the test software, which consists of the procedures to be used in
conformance testing;
- The establishment of test services.
This International Standard is applicable to all standards within the scope of the subcommittee within ISO/IEC JTCl responsible
for computer graphics and image processing.
