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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 22242 was prepared by Technical Committee ISO/TC 195, Building construction machinery and
equipment.

Introduction
A whole range and many different types of machinery are needed for building and maintaining traffic routes,
roads, highways, runways, aprons, etc. These can be divided into the following main groups, falling within the
particular scopes of ISO Technical Committees.
⎯ Tractors and machinery for agriculture and forestry (ISO/TC 23)
EXAMPLE Brush-cutters and brush saws, log loaders, portable chain saws, branches-shredders, drainage pipe
layers, digger ploughs and other machines defined in ISO 3339.
⎯ Earth-moving machinery (ISO/TC 127)
EXAMPLE Excavators, tractor dozers, scrapers, loaders, dumpers, trenchers, graders, rollers, vibratory plates,
rammers and other machines defined in ISO 6165, ISO 6747, ISO 7131, ISO 7132, ISO 7133, ISO 7134 and
ISO 8811.
⎯ Building construction machinery and equipment (ISO/TC 195)
EXAMPLE Formworks, drum mixers, machines and equipment for concrete-mix production, truck concrete
mixers and concrete transport skips, concrete pumps, vibrating beams, floating machines, concrete vacuum
treatment units, core drilling units and other machines defined in ISO 11375.
⎯ General-use machinery and equipment
EXAMPLE Power tools such as hammers, industrial vacuum cleaners, blowers, water pumps, portable chain
saws, liquid gas heating units, infrared heaters.
⎯ Machines and equipment designed especially for road construction and maintenance (ISO/TC 195).
This International Standard identifies and describes elements of this last group.
