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).

ISO 8437-2:2019(E)
Introduction
The structure of safety standards in the field of machinery is as follows.
a) Type-A standards (basic standards) give basic concepts, principles for design and general aspects
that can be applied to machinery.
b) Type-B standards (generic safety standards) deal with one or more safety aspects or safeguards
that can be used across a wide range of machinery:
1) type-B1 standards on particular safety aspects (e.g. safety distances, surface temperature,
noise);
2) type-B2 standards on safeguards (e.g. two-handed controls, interlocking devices, pressure
sensitive devices, guards).
c) Type-C standards (machinery safety standards) deal with detailed safety requirements for a
particular machine or group of machines.
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 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 provisions of this type-C standard are different from those which are stated in type-A or type-B
standards, the provisions of this type-C standard shall take precedence over the provisions of the other
standards for machines that have been designed and built according to the provisions of this type-C
standard.

Snow throwers — Safety requirements and test
procedures —
Part 2:
Pedestrian-controlled snow throwers
1 Scope
This document specifies safety requirements applicable to combustion engine powered pedestrian-
controlled snow throwers. It is intended to be used with ISO 8437-1 and ISO 8437-4 to achieve the full
requirements and means of verification for pedestrian-controlled snow throwers.
The ISO 8437 series deals with significant hazards, hazardous situations and events relevant to snow
throwers used as intended and under the conditions reasonably foreseeable by the manufacturer.
It does not apply to the following:
— electrically powered and battery powered snow throwers;
— hand-held snow throwers;
— airport or highway snow removal machines and equipment;
— machines intended for use in potentially explosive atmospheres.
It does not deal with hazards related to the following:
— battery circuits exceeding 42 V;
— mains connected starting motor;
— magneto grounding circuits;
— working environment;
— electromagnetic compatibility.
The ISO 8437 series is not applicable to machines that were manufactured before the date of its
publication.

4 Requirements for pedestrian-controlled snow thrower safety
4.1 General
The machines shall comply with the safety requirements and/or protective measures of this clause.
In addition, the machine shall be designed in accordance with the principles of ISO 12100 for hazards
relevant but not significant that are not dealt with by this document (e.g. sharp edges on the outside of
the machine).
4.2 Controls
4.2.1 General
Operator controls shall be located within, and have a range of movement which remains within, the
operator control position given in Figure 1, except for
— engine controls,
— snow discharge chute, and
— snow discharge deflector.
Compliance shall be checked by inspection and measurement.
The controls shall be designed such that they can be operated by an operator with and without arctic
mittens (see Figure 2).
Compliance shall be checked by functional test.
No controls shall be in any hazard zone (see Figure 1). The discharge hazard zone shall be limited by
a line tangent to, or in line with, the inside walls of the discharge chute. The discharge hazard zone
moves as the discharge chute is moved from side to side. The operator position shall not intersect the
discharge hazard zone.
Compliance shall be checked by inspection and functional test.
Controls where the purpose is not obvious to the user shall have the function, direction and/or method
of operation clearly identified by a durable label or mark.
Compliance sha
