Introduction
This document is a type-C standard as stated in EN 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.
1 Scope
This document together with EN 474-1:2022 deals with all significant hazards, hazardous situations and
events relevant to tractor-dozers when used as intended and under the conditions of misuse which are
reasonably foreseeable by the manufacturer (see Annex A) associated with the whole lifetime of the
machine as described in EN ISO 12100:2010, 5.4.
The following significant and relevant hazards are not covered in this document:
— Laser;
— Lightning.
The requirements of this document are complementary to the common requirements formulated in
EN 474-1:2022. This document does not repeat the requirements of EN 474-1:2022 but supplements or
modifies the requirements for tractor-dozers.
This document does not provide requirements for main electrical circuits and drives of machinery when
the primary source of energy is an external electrical supply.
This document does not provide performance requirements for safety related functions of control
system(s).
This document does not deal with towing of trailers.
This document does not deal with demolition machinery.
This part also deals with fork application, log handling application, single heavy object handling
application and lifting operation application.
This document is not applicable to tractor-dozers which are manufactured before the date of publication
of this document by CEN.

3.1
tractor-dozer
self-propelled crawler or wheeled machine with equipment having either dozing attachment which cuts,
moves, and grades material through forward motion of the machine or a mounted attachment used to
exert a push or a pull force (see EN ISO 6165:2012)
4 Safety requirements and/or protective/risk reduction measures
4.1 General
4.1.1 Context
Tractor-dozers shall comply with the safety requirements and/or protective/risk reduction measures of
this clause. In addition, the machines shall be designed according to the principles of EN ISO 12100:2010
for relevant but not significant hazards which are not dealt with by this document.
4.1.2 Specific relation to EN 474-1
Tractor-dozers shall comply with the requirements of EN 474-1:2022, as far as not modified or replaced
by the requirements of this part.
There are general requirements specified in EN 474-1:2022 that are not applicable because the risk
assessment has shown that for tractor-dozers the corresponding hazard does not exist. For tractor-
dozers 4.2.2, 4.3.5, 4.12, 4.14.2.3, 4.22.5, Annex B and Annex C in EN 474-1:2022, are not applicable.
