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.

Introduction
This ISO standard is a "Type C" standard as defined in ISO 12100.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this standard.
Where there are provisions of this type-C standard which are different from those which are stated in type A or
B standards, the provisions of this type-C standard take precedence over the provisions of the other standards,
but only for trucks that have been designed and built in accordance with the provisions of this type-C standard.

Rough-terrain trucks — Visibility — Test methods and their
verification
1 Scope
This standard applies to rough-terrain variable-reach trucks (herein-after referred to as ‘trucks’) that have a
specific seated operator’s position, on the left hand side of the boom, or centre position (excluding operator
position on the right side of the boom).
For the purpose of this standard, where specified, truck dimensions do not include equipment such as working
lights, mirrors, etc.
This standard specifies a static test method for determining and evaluating the operator’s visibility on a
rectangular 1 m boundary close around the rough-terrain variable-reach truck and on a 12 m visibility test
circle. Performance requirements for visibility are specified in this standard.

This standard does not apply to
- trucks designed to handle freight containers (reach stackers)
- articulated telescopic wheel loaders
- slewing trucks
- lorry mounted trucks
Note: The method used does not capture all of the aspects of the operator’s visibility, but provides information
to assist in determining the acceptability of visibility from the truck.

references, only the edition cited applies. For undated references, the latest edition of the referenced

light bulbs, laser, LEDs or equivalent). Each light source shall be horizontally movable on the light bar from
32,5 mm up to 202,5 mm on each side of the light source position centre point. It shall be possible to rotate
the light bar through 360° around the light source position centre point. The light source position centre point
shall be located 680 mm above and 20 mm in front of the seat index point (SIP) as described by ISO 5353
(see Figure 1).
4.2 Vertical test object
The vertical test object shall be 1,5 m high, 100 mm wide and be maintained substantially perpendicular to the

4.3 Observation mirror
To determine the maskings on the visibility test circle or the rectangular 1 m boundary, a hand held mirror can

object. The observation mirror shall have a maximum size of 100 mm x 150 mm.
5 Truck test configuration
5.1 Equipment of the truck
The truck shall be equipped with standard fork arms and equipment according to the manufacturer’s standard
