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.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

This document was prepared by Technical Committee ISO/TC 127, Earth-moving machinery,
Subcommittee SC 4, Terminology, commercial nomenclature, classification and ratings.

Earth-moving machinery — Hydraulic breakers —
Terminology and commercial specifications
1 Scope
This document establishes the terminology and content of commercial specifications for hydraulic
breakers which are mounted as an attachment on a carrier, typically earth-moving machinery such as
an excavator, backhoe loader, skid steer loader, and compact loader as defined in ISO 6165; or mounted
on a rig, pedestal boom system, demolition robot, etc., at the end of an arm.
Hydraulic breakers are typically used to demolish or break rock, concrete, brickwork, asphalt, etc.
This document does not cover breakers powered by pneumatic, thermomechanical, or electromagnetic
energy. This document does not cover portable or hand-held breakers either.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at http:// www .electropedia .org/
3.1
carrier
mobile or stationary machinery that provides power and a range of motion for the mounted item
Note 1 to entry: Mobile machinery is typically an excavator, backhoe loader, skid steer loader, or compact loader.
Stationary machinery is typically a pedestal boom system, demolition robot, etc.
3.2
attachment
assembly of components that can be mounted onto the carrier (3.1) for specific use
[SOURCE: ISO 6746-2:2003, 3.5, modified — The term “base machine and equipment” has been replaced
with “carrier”.]
3.3
hydraulic breaker
percussive hydraulic attachment (3.2) used for breaking up concrete, rock, brickwork, asphalt, etc.
3.3.1 Accumulator
3.3.1.1
hydraulic accumulator
pressure storage reservoir that enables a hydraulic system to cope with extremes of demand and to
smooth out pulsations

3.3.1.2
piston accumulator
energy storage chamber charged with nitrogen into which the upper end of the piston (3.3.8)
reciprocally projects and which imparts stored energy onto the upper surface area of the piston to
assist with piston acceleration
3.3.2
back head
device that closes the upper end of the cylinder and has a space into which the upper end of the piston
(3.3.8) reciprocally projects
3.3.3
bracket
side plate
device that supports the power cell (3.3.7) which includes mounting holes to either bolt on to the carrier
(3.1) mounting adapter (3.3.11) or to connect directly to the mounting flange holes on the carrier
3.3.4
tool
device that transmits the impact energy of the reciprocating piston (3.3.8) to the material to be broken
3.3.5
front head
device that attaches to the lower end of the cylinder to guide and support the tool (3.3.4)
3.3.6
housing
device that encloses the power cell (3.3.7) on all sides and has mounting holes or is connected to the
carrier (3.1) with a mounting adapter (3.3.11)
Note 1 to entry: Types of housings can be side-mount open, top-mount open, side-mount closed, and top-
mount closed.
Note 2 to entry: The refer
