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 com-
mittee 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 stan-
dardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
The main task of technical committees is to prepare International Standards. Draft International Stan-
dards adopted by the technical committees are circulated to the member bodies for voting. Publication
as an International Standard requires approval by at least 75% of the member bodies casting a vote.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of normative document:
— an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical ex-
perts in an ISO working group and is accepted for publication if it is approved by more than 50%
of the members of the parent committee casting a vote;
— an ISO Technical Specification (ISO/TS) represents an agreement between technical experts in an
ISO working group and is accepted for publication if it is approved by 2/3 of the members of the
parent committee casting a vote.
An ISO/PAS or ISO/TS is reviewed every three years with a view to deciding whether it can be trans-
formed into an International Standard.
Attention is drawn to the possibility that some of the elements of this part of ISO 10303 may be the
subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO/TS 10303–304 was prepared by Technical Committee ISO/TC 184,Industrial
automation systems and integration, Subcommittee SC4, Industrial data.
This International Standard is organised as a series of parts, each published separately. The structure of
this International Standard is described in ISO 10303-1.
Each part of this International Standard is a member of one of the following series: description meth-
ods, implementation methods, conformance testing methodology and framework, integrated generic re-
sources, integrated application resources, application protocols, abstract test suites, application inter-
preted constructs, and application modules. This part is a member of the abstract test suites series.

Introduction
ISO 10303 is an International Standard for the computer-interpretable representation and exchange of
product data. The objective is to provide a neutral mechanism capable of describing product data
throughout the life cycle of a product independent from any particular system. The nature of this de-
scription makes it suitable not only for neutral file exchange, but also as a basis for implementing and
sharing product databases and archiving.
This International Standard is organized as a series of parts, each published separately. The parts of
ISO 10303 fall into one of the following series: description methods, integrated resources, application
interpreted constructs, application protocols, abstract test suites, implementation methods, and confor-
mance testing. The series are described in ISO 10303–1. This part of ISO 10303 is a member of the
abstract test suite series.
The purpose of an abstract test suite is to provide a basis for evaluating whether a particular implemen-
tation of an application protocol actually conforms to the requirements of that application protocol. A
standard abstract test suite helps ensure that evaluations of conformance are conducted in a consistent
manner by different test laboratories.
This part of ISO 10303 specifies the abstract test suite for ISO 10303-204, application protocol Me-
chanical design using boundary representation. The abstract test cases presented here are the basis for
conformance testing of implementations of ISO 10303-204.
This abstract test suite is made up of two major parts:
— the test purposes, the specific items to be covered by conformance testing;
— the set of abstract test cases that meet those test purposes.
The test purposes are statements of the application protocol requirements that are to be addressed by
the abstract test cases. Test purposes are derived primarily from the application protocol’s application
elements and application interpreted model, as well as from other sources such as standards referenced by
the application protocol and requirements stated in the application protocol conformance requirements
clause.
The abstract test cases address the test purposes by:
— specifying the requirements for input data to be used when testing an implementation of the appli-
cation protocol;
— specifying the verdict criteria to be used when evaluating whether the implementation successfully
converted the input data to a different form.
The abstract test cases set the requirements for the executable test cases that are required to actually
conduct a conformance test. Executable test cases contain the scripts, detailed values, and other ex-
