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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are
cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all
such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

Introduction
This document 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 organisations, market surveillance, etc.).
Others can be affected by the level of machinery safety achieved with the means of this 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 the 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.
The ISO 13105 series deals with machinery designed for smoothing and finishing concrete on
construction sites. These machines are commonly referred to as “power trowels”.

INTERNATIONAL STANDARD ISO 13105-2:2023(E)
Building construction machinery and equipment —
Machinery for concrete surface floating and finishing —
Part 2:
Safety requirements and verification
1 Scope
This document specifies safety requirements for machines used for concrete surface floating and
finishing. This includes pedestrian-controlled equipment and ride-on equipment.
This document is not applicable to:
— internal or external vibrators or ancillary equipment used with internal and external vibrators, e.g.
air compressors, hydraulic power sources, and voltage transformers;
— remote-controlled or hand-held smoothing machines and self-acting (e.g. robotic) smoothing
machines;
— strike-off type machines commonly known as screeds.
This document deals with significant hazards, hazardous situations, or hazardous events relevant
to machinery for concrete surface floating and finishing (power trowels) when used as intended and
under conditions of misuse which are reasonably foreseeable by the manufacturer.
This document is not applicable to machines which are manufactured before the date of its publication.

4 Safety requirements and/or protective/risk reduction measures
4.1 Overview
Machinery shall conform to the safety requirements and/or protective/risk reduction measures of this
clause.
In addition, the machine shall be designed according to the principles of ISO 12100 for relevant but not
significant hazards (see Annex B), which are not dealt with by this document.
4.2 General requirements for all machines
4.2.1 Guarding of the rotating blades
A means shall be provided to protect the operator or bystanders from inadvertently coming in contact
with rotating blades. The guarding device shall be designed so that the operator can visually see the
interaction of the blades with the concrete surface and in conformity with the dimensions given in
Annex C.
If the guarding device is constructed of tubes (or bars), there shall be a gap not exceeding 90 mm
between the concentric tubes (or bars). See Figures C.1 and C.2. The distance between the tip of
the blade and the outer edge of the guarding device shall be dependent on the type of machine and
performance expected. For flotation of concrete close to a vertical wall, that difference can be near zero.
The lowest outer tube (or bar) of the blade guarding device shall be able to withstand an impact force,
directed horizontally towards the guarding device, equal to two times the mass of the machine without
exposing the blades to the deformation.
4.2.2 Blade guarding device ground clearance
The height of the lowest outer tube (or bar) of the blade guarding device with blades in the unpitched
position shall not exceed 60 mm from the concrete surface. See Figures C.1 and C.2.
4.2.3 Blade pitch adjustment
Whenever practicable, the adjustment of the blade pitch shall be carried out from the normal operating
position. Where this is neither possible nor practicable, means shall be provided to protect personnel
from contact with the blade, e.g. blade lock or equivalent. Instructions for blade pitch adjustment shall
be given in the operator's manual. See 6.1.2, t).
4.2.4 Electrical devices
4.2.4.1 Electrical contact of persons with live parts
4.2.4.1.1 Direct contact
Protection from direct contact with live parts shall be in accordance with IEC 60204-1:2016, 6.2.
4.2.4.1.2 Indirect contact
Protection from indirect contact with live parts shall be in accordance with IEC 60204-1:2016, 6.3.
4.2.4.2 External influences on electrical equipment
4.2.4.2.1 Damage to electrical equipment
The position of the electrical equipment in the machinery shall guarantee protection from mechanical
damage to electrical equipment.
Flexible leads with insulation meeting specification H 07 RN-F or A 07 RN-F in accordance with
EN 50525-2-21 or at least equivalent specification shall be used.
Plug devices shall be qualified for more difficult (rough) conditions in accordance with IEC 60309-1.
4.2.4.2.2 Protection from dust
Electrical components shall meet the dust protection requirements to IP-5X in accordance with
IEC 60529:2001, 13.4.
4.2.4.2.3 Protection from water
Electrical components shall meet the water protection requirements to IP-X5 in accordance with
IEC 60529:2001, 14.2.5.
4.2.4.3 Protection against residual voltages
Live parts having a residual voltage greater than 60 V after the supply has been disconnected shall be
discharged to 60 V or less within a time period of 5 s after disconnection of the supply voltage, provided
that this rate of discharge does not interfere with the proper functioning of the equipment.
4.2.4.4 Prevention of the occurrence of a touch voltage
For engine powered machines which generate electrical power above 60 V for accessories, the
requirements of IEC 60204-1:2016, 6.3.
