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 document 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).

Introduction
This document defines commercial specifications for road surface cleaning machines which are designed
to clean debris from improved road and pavement surfaces. These machines are typically equipped
with a pick-up system and can convey the spoil into the hopper which can be then be discharged at a
dumping ground, unload station, in a debris container or refuse reload stations. Road surface cleaning
machines are equipped with sweep gear to scarify debris.
Chassis-mounted sweepers typically have a large capacity hopper and are designed to operate on
streets, highways, airports and large vehicle parking areas (i.e. traffic areas) or industrial plants where
a larger volume of debris needs to be swept.
Self-propelled sweepers and pedestrian-controlled sweepers typically have a lesser capacity hopper
and, by design, are more manoeuvrable to clean debris from narrow streets, pedestrian zones or small
parking lots.
Towed sweepers (e.g. towed by a tractor or other vehicle) can be used for similar applications as
mentioned above.
Additional equipment for special cleaning applications can also be attached to a sweeper.

Sweepers — Commercial specifications
1 Scope
This document establishes content for commercial specifications for sweepers that are self-propelled
(see Annex A) with an integrated chassis, chassis-mounted, pedestrian-controlled or towed behind a
vehicle.
This document applies to road surface cleaning machines used in outdoor improved surface applications
for cleaning debris from public areas, roads, airports and industrial plants. This document does not
specifically cover the carrier vehicle or towing vehicle (e.g. lorry).
This document does not apply to:
— cleaning machines for winter maintenance;
— cleaning machines for indoor applications;
— rotary road brush attachments which can be coupled to tractors and other machinery;
— machines or components that are specifically designed for cleaning tram lines and rail tracks;
— industrial sweepers.

container which is attached to the machine by mechanical or pneumatic means, or by combination of each.
Note 2 to entry: Combinations of these types of road surface cleaning machines are possible.
3.1.1
chassis-mounted sweeper
sweeper (3.1), where the sweeping attachments are fixed or mounted on a carrier vehicle chassis

3.1.2
self-propelled sweeper
sweeper (3.1) with a specially designed chassis, where the sweeping attachments are integrated
