ISO 13766-1:2018(E)
Introduction
This document is a type-C standard as stated in ISO 12100:2010.
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 organisations, 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.
With the increasing use of electronic devices in areas where earth-moving and machinery operates, there
is a need to ensure that the machinery is provided with adequate immunity to external electromagnetic
fields. As more machinery is fitted with electrical and electronic devices, it is necessary to ensure that
the emissions of electromagnetic fields from the machinery meet acceptable limits.
Electrical and high frequency disturbances emerge during the normal operation of many parts of
machine devices and systems. They are generated within a large frequency range with different
electrical characteristics and by conduction or radiation, which can be imparted to other electrical/
electronic devices and systems by conduction or radiation. Narrowband signals generated by sources
of interference inside or outside the machinery can also be coupled into electrical/electronic systems
whereby they can influence the normal function of electrical/electronic devices.
Electrostatic discharges are relevant to the machinery because control elements can be positioned
outside the operator station where potential differences could emerge at contact points. Conducted
transients in power supply wiring must be considered because the machinery can contain open systems,
in which several devices or components can be combined to complement machine functionality.
While there are many existing standards for a variety of products and systems, the test method
presented by ISO 13766:2018 provides for the specific test conditions of the machinery within its scope
as well as the electrical/electronic sub-assemblies (ESA) or ESA separate from the machinery. The test
method recognizes that due to their size and usage, the arrangement of the machines in the test facility
needs to be representative of their typical operating characteristics. This document provides test
methods and criteria which are acceptable for the machine types it covers, considering their unique
characteristics and operating parameters.
Because the machinery has a number of systems that consist of components that can be used on a
variety of machine types, the approach of defining ESA or separate ESAs for these components is
applied for the immunity and emissions test methods. This allows these components to be evaluated by

the test method in existing laboratory facilities consisting of specially equipped shielded rooms. When
electrical/electronic sub-assembly tests are conducted, it is necessary to consider any additional effects
imparted by wiring systems used to connect the sub-assemblies into the machinery. The tests can also
be conducted on the machinery.

NOTE In most regions of the world radiated immunity testing for large machines in open area test sites is
legally prohibited. Below 1 GHz conducted testing methods are available as a substitute. Above 1 GHz there is no
alternative to radiated immunity testing, and it is possible to perform the radiated immunity testing on ESA level
in an anechoic chamber.
When testing ESA it recommended that the integrity of the final system when combined at machine
level be tested.
The requirements of this document are also deemed to be fulfilled when the machinery has no such
equipment for which an immunity or emission test is required. In this case, no tests are necessary. For
all exceptions, see Clause 5.
4.1.1.2 Performance criteria for complete machines
The performance requirements are met if the machinery operates as intended and without unacceptable
degradation when tested in accordance with the requirements of 4.2, 4.3, 4.4 and 4.8.
4.1.1.3 Performance criteria for ESA
The performance requirements of this document are met if the machine’s ESA or separate ESA operate
as intended and without unacceptable degradation for their application in machinery in accordance
with the requirements of 4.5, 4.6, 4.7, 4.8 and 4.9.
4.1.2 Test specimen
The test specimen may be of a machine type or ESA type as defined in 3.18 and 3.19.
If a single test specimen is to be used to judge the performance of a population of like machinery, the
reference limits for emissions and immunity shall be made more restrictive by a 20 % reduction for
emissions limits and a 25 % increase for immunity limits so as to account for variability of emission and
immunity due to any manufacturing variations of machine or ESA types and testing factors.
For a subsequent test on similarly configured machinery, conformity to the reference limits shall be
accepted as fulfilment of the requirements of this document.
For electrostatic discharge and conducted transients, the reference limits are valid for all testing of any
test specimen.

4.1.3 Additional requirements for immunity tests
When a test specimen is subjected to the immunity requirements, operator controls and any automatic
controls for the machinery and any attachments or machinery shall remain functional so as to provide
continued control of the machinery. This also applies to secondary or shut-down systems which are
intended to be operated when the primary control has failed.
4.2 Specifications for broadband electromagnetic emission radiated from machinery
4.2.1 Method of measurement
The electromagnetic radiation shall be measured using the method specified in Annex B at either of the
defined antenna distances. The choice of antenna distance is at the option of the user.
4.2.2 Broadband reference limits
For measurements made using the method specified in Annex B and a machinery-to-antenna spacing of
(10,0 ± 0,2) m, the emission reference limit shall be
— 34 dB (µV/m) (50 µV/m) in the 30 MHz to 75 MHz frequency band,
— 34 dB (µV/m) to 45 dB (µV/m) (50 µV/m to 180 µV/m) in the 75 MHz to 400 MHz frequency band, this
limit increasing logarithmically (linearly) with frequencies above 75 MHz, as shown in Figure A.1, and
— in the 400 MHz to 1 000 MHz frequency band, shall remain constant at 45 dB (µV/m) (180 µV/m).
For measurements made using the method specified in Annex B using a machinery-to-antenna spacing
of (3,0 ± 0,05) m, the emission reference limit shall be
— 44 dB (µV/m) (160 µV/m) in the 30 MHz to 75 MHz frequency band,
— 44 dB (µV/m) to 55 dB (µV/m) (160 to 562 µV/m) in the 75 MHz to 400 MHz frequency band, this limit
increasing logarithmically (linearly) with frequencies above 75 MHz as shown in Figure A.2, and
— in the 400 MHz to 1 000 MHz frequency band, shall remain constant at 55 dB (µV/m) (562 µV/m).
On a single test specimen, the measured values, expressed in dB (µV/m) or (µV/m), shall be at least
2,0 dB or (20 %) below the reference limits.
NOTE The 20 % factor applies regardless of the use of CISPR 12:2007 or CISPR 12:2007+AMD1: 2009.
4.3 Specifications concerning narrowband electromagnetic emission radiated from
machinery
4.3.1 Method of measurement
The electromagnetic emission shall be measured using the method specified in Annex C, at either of the
defined antenna distances. The choice of antenna distance is at the option of the user.
4.3.2 Narrowband reference limits
For measurements made using the method specified in Annex C using a machinery-to-antenna spacing
of (10,0 ± 0,2) m, the emission reference limit shall be
— 24 dB (µV/m) (16 µV/m) in the 30 MHz to 75 MHz frequency band,
— 24 dB (µV/m) to 35 dB (µV/m) (16 µV/m to 56 µV/m) in the 75 MHz to 400 MHz frequency band, this
limit increasing logarithmically (linearly) with frequencies above 75 MHz as shown in Figure A.3, and
— in the 400 MHz to 1 000 MHz frequency band, shall remain constant at 35 dB (µV/m) (56
