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.

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 195, Building construction machinery and
equipment, Subcommittee SC 1, Machinery and equipment for concrete work.
ISO 13105 consists of the following parts, under the general title Building construction machinery and

Introduction
This part of ISO 13105 is a type-C standard as stated in ISO 12100.
This part of ISO 13105 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 part of ISO 13105
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 part of ISO 13105.
The machinery concerned and the extent to which hazards, hazardous situations, or hazardous events
are covered are indicated in the Scope of this part of ISO 13105.
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.
ISO 13105 deals with machinery designed for smoothing and finishing concrete on construction sites.
These machines are commonly referred to as “power trowels.”
INTERNATIONAL STANDARD ISO 13105-2:2014(E)
Building construction machinery and equipment —
Machinery for concrete surface floating and finishing —
Part 2:
Safety requirements and verification
1 Scope
This part of ISO 13105 specifies safety requirements for machines used for concrete surface floating and
finishing. This includes pedestrian-controlled equipment and ride-on equipment.
It is not applicable to
— internal or external vibrators or ancillary equipment used with internal and external vibrators, for
example, air compressors, hydraulic power sources, and voltage transformers,
— remote-controlled or hand-held smoothing machines and self-acting (robotic) smoothing machines,
and
— strike-off type machines commonly known as screeds.
This part of ISO 13105 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 part of ISO 13105 is not applicable to machines which are manufactured before the date of its
publication.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 12100, ISO 13105-1, and the
following shall apply.
3.1
nylon 6/6 substrate
polyhexamethylene adipamide material

4 Safety requirements and/or protective/risk reduction measures
Machinery shall comply with 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 which are not dealt with by this part of ISO 13105.
4.1 General requirements for all machines
4.1.1 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.
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 ISO 13105-1:2014, Figures A.1 and A.2.
The lowest outer tube (or bar) of the blade guarding device shall be able to withstand an impact force
equal to two times the weight of the machine without exposing the blades to the deformation.
4.1.2 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 ISO 13105-1:2014, Figures A.1 and A.2.
4.1.3 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, item t).
