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.

Introduction
This document addresses electronic and electrical systems used for functional safety in earth‐
moving machinery.
The structure of safety standards in the field of machinery is as follows.
Type‐A standards (basis standards) give basic concepts, principles for design and general aspects
that can be applied to machinery.
Type‐B standards (generic safety standards) deal with one or more safety aspects, or one or more
types of safeguards that can be used across a wide range of machinery:
— type‐B1 standards on particular safety aspects (e.g. safety distances, surface temperature,
noise);
— type‐B2 standards on safeguards (e.g. two‐hands controls, interlocking devices, pressure
sensitive devices, guards).
Type‐C standards (machinery safety standards) deal with detailed safety requirements for a
particular machine or group of machines.
This document, when taken together with the other parts of ISO 19014, is a type‐C standard as
stated in ISO 12100.
This document is of relevance, in particular, for the following stakeholder groups representing the
market players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance
etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by
the above‐mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e. g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above‐mentioned stakeholder groups have been given the possibility to participate at the
drafting process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous
events are covered are indicated in the Scope of this document.
When requirements of this type‐C standard are different from those which are stated in type‐A or
type‐B standards, the requirements of this type‐C standard take precedence over the requirements
of the other standards for machines that have been designed and built according to the
requirements of this type‐C standard.

4 Functional status classifications
4.1 Class A
All safety functions of the device under test (DUT) perform as designed during and after the test.
4.2 Class B
All safety functions of the DUT perform as designed during the test. The DUT may perform outside of the
designed tolerance during the test; however, all functions shall automatically return within the specified
tolerance after the test. Memory functions shall remain class A.
The functions of the DUT that are required to perform as designed during the test, and the functions that
may perform beyond the specified tolerance, shall be specified by the machine manufacturer.
4.3 Class C
For DUTs that are powered and monitored, one or more functions of a DUT do not perform as designed
during the test, but return automatically to normal operation after the test.
For DUTs that re not powered and monitored, the DUT performs as designed after the test.
4.4 Class D
One or more functions of a DUT do not perform as designed during the test and do not return to normal
operation after the test until the DUT is reset.
5 Tests and requirements
5.1 General
The test conditions specified in this document are the minimum requirements. The EMM manufacturer
Deleted: equipment
shall ensure electrical and electronic components are suitable for the environment in which they are used.
The EMM manufacturer shall determine the use environment as it applies to the test conditions in this
Deleted: equipment
document. The environmental requirements for each application depend on its mounting location (engine
compartment, operator station, chassis, etc.), which shall be taken into account when developing the test
specification.
Significant variation in environmental conditions due to diurnal and seasonal cycles can be expected and
shall be considered when testing according to this document.

Deleted: /FDIS
The EMM manufacturer shall test any components that are likely to be submerged in, or exposed to,
Deleted: equipment
chemical agents (mining liquids, salts, alkaline, fertilizer, etc.) and ensure the components are immune to
contamination or degradation.
Components that are immune to contaminants may be exempt from testing if the EMM manufacturer
provides documentary evidence to that effect. The EMM manufacturer shall determine suitability for
Deleted: equipment
chemical exposure according to ISO 16750‐5. Resistance to the specified chemical agents should be
considered as early as possible (e.g. during the material selection process.)
See Annex A for an example of a test checklist, which includes a column for the EMM manufacturer to
Deleted: equipment
document the rationale for excluding a test.
NOTE If explosion proofing is required, refer to IEC 60079. National or regional requirements can apply.
5.2 Dust
5.2.1 Purpose
Electronic components (controllers, joysticks, displays, switches, solenoids, etc.) adversely affected by
dust ingress shall be protected against the ingress of dust present in the operating environment.
This test verifies that the DUT is immune to dust intrusion. Failure mode is electrical or mechanical
malfunction caused by dust intrusion into the DUT housing or dust settling on the surface of electrical
contacts.
Components that are sealed and meet a minimum IP rating of 6X according to IEC 60529 or IP rating of
IP6KX according to ISO 20653 may be exempt from the requirements of this test.
5.2.2 Test method
Dust testing shall be performed in accordance with ISO 20653 or IEC 60529. The DUT shall be mounted
according to its normal mounting orientation in the EMM.
The functional status shall be class C (4.3).
5.3 Chemical resistance
5.3.1 Purpose
This test verifies that the DUT is protected against contact with acids, corrosive gases and salts that can be
present in the operating environment.
DUT exposed to specified chemical agents shall be resistant to those agents. The DUT shall be tested with
all chemicals with which it is likely to come into contact, except DUT materials for which documentary
evidence shows immunity to the contaminant and, therefore, need not be tested.
A material is considered to be immune to a contaminant if there is no change in properties sufficient to
affect the material performance.
Manufacturer and type of chemical agents shall be agreed upon between the test laboratory and EMM
manufacturer.
5.3.2 Test method
If required, chemical resistance testing shall be performed in accordance with ISO 16750‐5. The DUT need
not be powered and monitored during this test.
The functional status shall be class C (4.3).
