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-

plicit information required to conduct a conformance test on a specific implementation of the application
protocol.
At the time of publication of this document, conformance testing requirements had been established
for implementations of application protocols in combination with ISO 10303–21 and ISO 10303–22.
Accordingly, this part of ISO 10303 only specifies test purposes and abstract test cases appropriate to
such implementations.
For ISO 10303–21, two kinds of implementations, preprocessors and postprocessors, must be tested.
Both these are addressed in this abstract test suite.
For ISO 10303–22, a class of applications will possess the capability to upload and download appli-
cation protocol-compliant standard data access interface-models and/or schema instances to and from
applications that implement the standard data access interface. This abstract test suite addresses such
applications.
The abstract test cases presented here are the basis for conformance testing of implementations of ISO
10303-204. The test cases in this part of ISO 10303 are documented in the EXPRESS-I language and
can potentially be readily adapted to other implementation methods.

4 Test purposes
This clause specifies the test purposes for this part of ISO 10303. Test purposes are derived from the
information requirements contained in clause 4 of ISO 10303-204, the AIM EXPRESS schema in an-
nex A of ISO 10303-204, and AIC parts referenced by ISO 10303-204. The test purposes are organized
in this clause by type.
AE test purposes are individually identified by the prefix “ae” in the test purpose number. Each test
purpose derived from the information requirements shall be interpreted as:
Correctly instantiate in the implementation under test the semantic associated with the
unique application concept corresponding to (insert test purpose here) in at least one test case
within the test suite.
AE test purposes apply to the input specifications of both preprocessor and postprocessor test cases. AE
test purposes are derived from the AP information requirements as follows:
— application objects (4.2 of ISO 10303-204). A test purpose derived from an application object is
a simple statement of the object’s name. Each application object test purpose is documented in a
separate subclause.
— application objects with categorisations (subtypes) (4.2 of ISO 10303-204). Test purposes derived
from application objects with categorisations are statements of the application object name as a
specific subtype.
— application object attributes (4.2 of ISO 10303-204). Test purposes derived from application object
attributes are statements of the application object name with a specific attribute name.
— application asertions (4.3 of ISO 10303-204). Test purposes derived from application assertions are
statements describing the relationship between two application objects. Application assertion test
purposes address the directions of relationships as well as the number (cardinality) of relationships.
Each application object test purpose is listed as a separate subclause, with its related application object
attribute test purposes. The application assertion test purposes form another subclause.
AIM test purposes are identified by the prefix “aim” in the test purpose number. Each test purpose
derived from the AIM EXPRESS shall be interpreted as follows:
Correctly instntiate in the implementation under test the AIM element associated with the
unique AIM entity corresponding to (insert test purpose here) in at least one test case within
the test suite.
AIM test purposes apply to the input specifications of postprocessor test cases only. AIM test purposes
are derived directly from the expanded EXPRESS listing contained in annex A of ISO 10303-204 as
follows:
— AIM entities. A test purpose derived from an AIM element is a simple statement of the entity name.
— AIM entity attributes. Test purposes derived from AIM entity attributes are statements of the AIM
entity with a given attribute.
Each AIM entity test purpose is grouped with its attribute test purposes, all of which are contained in
4.2.
Other test purposes are derived from implicit domain requirements, rule checking requirements and from
the AICs referenced by ISO 10303-204. Each other test purpose is a statement of some requirement that
shall be met by any conforming implementation. Other test purposes are grouped in clause 4.4 and later.
AE and AIM test purposes are individually identified by the prefix ‘ae’ or ‘AIM’ and a number which
relates to the UoF of origin. The codes used for UoF identification are given below.
Table 1 – Test purpose source identification
Source UoF AE test purpose number AIM identifier code
Advanced B-rep UoF and AIC ae2 - ae99 aim8 - aim105, aim107 - aim172

NOTE 1 Many of the AE test purposes for the advanced B-rep UoF are also applicable to the elementary B-rep
UoF. In such cases a multiple reference is given to the relevant test cases.
4.1 Application element test purposes
AE test purposes are individually identified by the prefix “ae” in the test purpose number. Each test
purpose derived from the information requirements shall be interpreted as:
Correctly instantiate in the implementation under test the semantic associated with the unique application
concept corresponding to (insert test purpose here) in at least one test case within the test suite.
Correctly instantiating an information requirement implies that the semantics of the application element
are preserved between the input and the output of a test as well as conformance to the reference path
specified in the mapping table of the AP. AE test purposes apply to the input specifications of both
preprocessor and postprocessor test cases. AE test purposes are derived from the AP information re-
quirements as follows:
— application objects (4.2 of ISO 10303-204). A test purpose derived from an application object is
a simple statement of the object’s name. Each application object test purpose is documented in a
separate subclause.
— application objects with categorisations (subtypes) (4.2 of ISO 10303-204). Test purposes derived
from application objects with categorisations are statements of the application object name as a
specific subtype.
— application object attributes (4.2 of ISO 10303- 204). Test purposes derived from application object
attributes are statements of the application object name with a specific attribute name.
— application assertions (4.3 of ISO 10303-204). Test purposes derived from application assertions are
statements describing the relationship between two application objects. Application assertion test
purposes address the directions of relationships as well as the number (cardinality) of relationships.
Each application object test purpose is listed as a separate subclause, with its related application object
attribute test purposes and assertion test purposes.
