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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards 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.
Attention is drawn to the possibility that some of the elements of this part of ISO 8178 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 8178-6 was prepared by Technical Committee ISO/TC 70, Internal combustion engines,
Subcommittee SC 8, Exhaust gas emission measurement.
ISO 8178 consists of the following parts, under the general title Reciprocating internal combustion engines —

ISO 8178-6:2000(E)
Introduction
Results of an emissions test shall be presented clearly and should include all information pertinent to the derivation
of the emission test results. An accuracy or uncertainty analysis relevant to the test system used and engine being
evaluated should be made by the laboratory. A record shall be made of the measurement equipment being used,
the ambient conditions, the engine performance and the fuel used. Recommendations for the data to be recorded
are given regardless to the type of fuel being used.
The data format recommended in this part of ISO 8178 is intended to be used by individuals measuring emissions
using ISO 8178-1, ISO 8178-2, ISO 8178-9 or ISO 8178-10, but is not intended to contradict or replace existing
data formats which may be required by some regulatory bodies.
As expressed in ISO 8178-1 and ISO 8178-2, the emission results shall be stated in either "g/kWh" (preferred) or in
"g/m ". It should be noted that some regulators require the results to be expressed in unique measurement units;
this should be determined prior to testing.

Part 6:
Report of measuring results and test
1 Scope
This part of ISO 8178 specifies as a standard data format for reporting the measurement results of exhaust
emissions from RIC engines for mobile, transportable and stationary use, excluding engines for motor vehicles
primarily designed for road use. This part of ISO 8178 may be applied to engines used e.g. earth-moving
machines, generating sets and for other applications. This part of ISO 8178 applies to measurement in the
laboratory and at site.
For engines used in machinery covered by additional requirements, (e.g. occupational health and safety
regulations, dust regulations for powerplants) additional test conditions and special evaluation methods may apply.
NOTE Since the standard report format defined in this part of ISO 8178 is intended to be applicable to all types of internal
combustion engine, in certain cases some items are not necessary for specific engines and/or tests, especially when measuring
at site. On the other hand, some additional items might be necessary according to test purposes. Deletion and addition of items
to be reported should be based on agreement between the parties involved.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this part of ISO 8178. For dated references, subsequent amendments to, or revisions of, any of these publications
do not apply. However, parties to agreements based on this part of ISO 8178 are encouraged to investigate the
possibility of applying the most recent editions of the normative documents indicated below. For undated
references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain

5 Emissions test report
5.1 Introduction
The recommended test report consists of eleven data sheets (see annex A) that contain all the information
pertinent to a test run in a very compact way. The test report is a single document that can be filed easily for later
review of the test results by authorities, customers and engine manufacturers. It incorporates the final test results
and the information needed to trace the final results to the values originally measured, as well as the information on
the test engine, the test cell equipment and the test fuel. The report format is applicable to all test cycles and fuels.
5.2 General information
Table A.1 includes the information essential for engine approval, such as engine identification, engine application,
test cycle and test identification. The emission test results may be listed for five different test cycles, if applicable.
The gaseous and particulate emissions shall be expressed in grams per kilowatt hour whenever possible. Other
units shall be indicated if used according to the provisions laid down in the scope. The smoke test results shall be
listed for the smoke cycle applicable to the indicated application. The smoke values shall be expressed per metre
whenever possible. Exceptions are only allowed if regulators require other units.
5.3 Engine information
Table A.2 contains the basic features of the engine under test. This information is sufficient to build up an engine
with the same emission behaviour for confirmatory testing. If more information is demanded by authorities or
customers, this may be appended to the test report. Table A.3 and Table A.4 contain other information to identify
the features of the engine family and group respectively. These features are derived from ISO 8178-7 for engine
family and ISO 8178-8 for engine group. If the engine family or group concept does not apply for the engine under
test, Table A.3 or Table A.4 does not have to be submitted.
