Tractors for agriculture and forestry — Roll-over protective structures — Static test method and acceptance conditions
ISO 5700:2013 specifies a static test method and the acceptance conditions for roll-over protective structures (cab or frame) of wheeled or tracked tractors for agriculture and forestry. It is applicable to tractors having at least two axles for wheels mounted with pneumatic tyres, or having tracks instead of wheels, with an unballasted tractor mass of not less than 600 kg and a minimum track width of the rear wheels greater than 1 150 mm. It is not applicable to tractors having a mass ratio (maximum permissible mass / reference mass) greater than 1,75.

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. www.iso.org/directives

Introduction
Testing of roll-over protective structures (ROPS) for wheeled or tracked tractors for agriculture and
forestry aims at avoiding or limiting risks to the driver resulting from accidental overturning during
normal operation (e.g. field work) of the tractor. The strength of the ROPS is tested by applying static
loads and a static crushing test to simulate actual loads which can be imposed on the cab or frame when
the tractor overturns either to the rear or to the side without free fall. The tests allow observations to be
made on the strength of the structure and the attachment brackets to the tractor and also of the tractor
parts that could be affected by the load imposed on the structure.
Provision is made to cover both tractors with the conventional forward-facing driver’s position only,
as well as those with a reversible driver’s position. For tractors with a reversible driver’s position, a
clearance zone is defined to be the combined clearance zones for the two driving positions. The point of
application of the side loading is determined as the mid-point between the seat index points measured
in the two positions.
It is recognized that there could be tractor designs — for example, lawn-mowers, narrow vineyard
tractors, low profile tractors used in low buildings with limited overhead clearance, orchards, etc., stilt
tractors and certain forestry machines such as forwarders — for which this International Standard is
not appropriate.
This International Standard specifies technical performance requirements, associated test procedures
and performance test report information. Technical harmonization with OECD is ensured by the
Maintenance Agency operating as specified in Annex C.

1 Scope
This International Standard specifies a static test method and the acceptance conditions for roll-over
protective structures (cab or frame) of wheeled or tracked tractors for agriculture and forestry.
It is applicable to tractors having at least two axles for wheels mounted with pneumatic tyres, or having
tracks instead of wheels, with an unballasted tractor mass of not less than 600 kg and a minimum track
width of the rear wheels greater than 1 150 mm. It is not applicable to tractors having a mass ratio
(maximum permissible mass / reference mass) greater than 1,75.
