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 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 70, Internal combustion engines.

ISO 8528-13:2016(E)
This corrected version of ISO 8528-13:2016 incorporates the following corrections plus other minor
editorial modifications.
6.8.3.5 was corrected as follows:
b) When the accessible hot surfaces are less than 10 cm they shall be verified in accordance with
6.8.3.1.
b 1) The surfaces temperatures shall be verified by measurement,
c 2) The generating set shall be operated at its rated power until the surface temperatures stabilize,
d 3) The test shall be conducted in a well-ventilated location not directly exposed to sunshine,
e 4) If the test is conducted at an ambient temperature outside of the nominal (20 ± 3) °C the
reported temperatures shall be corrected by Formula (1):
Annex C b) 7) was corrected as follows:
Since the choice of protection arrangement to be carried out depending depends on the characteristic
of the generator, running conditions and scheme of grounded liaisons determined by the user, the
instructions and operation and instructions manual shall contain all information needed to the user
to carry out correctly these protective measures according to the user (information for grounded,
allowable lengths of connection cables, devices of complementary protection, etc.).

4 General
If the installation of a generating set can create hazards in addition to those covered by this part of
ISO 8528, the safety requirements and/or protective measures related to these additional hazards
are the responsibilities of the installer, if necessary with the agreement of the manufacturer of the
generating set. The installer will be responsible for ensuring compliance for the additional hazards
arising because of the installation.
5 Hazards
The hazards relevant to RlC engine driven generating sets that shall be considered in order to prevent
personal injury are listed in Annex A.
6 Safety requirements and tests
6.1 General
Machinery shall comply with the safety requirements and/or protective measures of this Clause. In
addition, the machine shall be designed according to the principles of ISO 12100 for relevant but not
significant hazards, which are not dealt with by this part of ISO 8528.
6.2 Starting system
6.2.1 Requirements
Starting systems can be triggered manually or automatically.
Electrical starting systems normally operate at voltages of 24 V or below. Electrical starting systems
above 24 V are not dealt with in this part of ISO 8528 and the installer of the engine shall ensure safe
operation after connecting the engine to the driven machinery.
For engines with compressed air starting, the starting pneumatic system shall comply with the
installation requirements and with the operation and safety information specified in the manuals
provided by the starting system components suppliers.
Crank handle starting systems shall meet the requirements specified in ISO 11102-1 and ISO 11102-2.
In addition, the following requirements apply:
— starting handles shall have sufficient clearance from the mounting surface to ensure safe turning;
— diesel engines with a manual starter shall have a decompression facility which shall not be required
to be hand-held during cranking.
ISO 8528-13:2016(E)
The only permissible hand starting systems are crank handle (as defined above) and recoil starting
devices as described in ISO 14314. The marking required in ISO 14314:2004, 7.3 shall not apply.
6.2.2 Verification
Compliance with the requirements shall be verified by inspection and testing of the starting systems.
6.3 Stopping
6.3.1 Requirements
6.3.1.1 Normal stopping
All generating sets shall have a normal stopping device which can be manually or automatically
actuated. Stopping controls shall remain in the stop position when operated. This shall operate by a
device ensuring the cutting off of the fuel or the ignition (for spark ignition engines) supply. This device
should include an air supply cut-off.
6.3.1.2 Stopping in case of failure
Generating sets except low power generating sets shall be provided with an automatically actuated
stopping device in case of failure.
This device shall monitor one or more signals of the generating set and if these signals are out of the
allowable range it shall trigger the automatic stop.
The main signals used to actuate automatic stopping may include, but not be limited to, the following:
a) for the RIC engine
1) overspeed,
2) low lubricating oil pressure,
3) high coolant temperature, and
4) low coolant level;
b) for the generator
1) excessive overvoltage, and
2) overload.
These signals or other measures used to actuate automatic stopping shall be specified depending on the
application.
6.3.2 Verification
Normal stopping shall be verified by inspection and testing of the stopping device in manual and in
automatic modes (if provided in the application).
Automatic stopping in case of failure shall be verified by testing the action of typical failure modes
in operating conditions (an appropriate method shall be used to create typical failure conditions, e.g.
manual triggering, short-circuiting of contacts).

ISO 8528-13:2016(E)
6.4 Emergency stopping
6.4.1 Requirements
