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 12649 was prepared by Technical Committee ISO/TC 130, Graphic technology.
Introduction
During the development of this International Standard, existing relevant standards of other countries were
taken into consideration. An effort has been made to harmonize the requirements of all countries, recognizing
that national standards or laws may dictate national requirements. In cases where it was known that there is a
national requirement that differs from this International Standard, that has been noted.
This International Standard was developed to harmonize three U.S. safety standards:
 ANSI B65.2, Safety standard — Binding and finishing systems,
 ANSI B65.3 Safety standard — Guillotine cutters, mill trimmers, and integral handling equipment,
 ANSI B65.4, Safety standard — Three-knife trimmers, including rotary, and single- and multiple-knife
trimmers;
and three European standards:
 prEN 1010-1, Safety of machinery — Safety requirements for the design and construction of printing and
paper converting machinery — Part 1: Common requirements,
 EN 1010-3, Safety of machinery — Safety requirements for the design and construction of printing and
paper converting machinery — Part 3: Cutting machines,
 EN 1010-4, Safety of machinery — Safety requirements for the design and construction of printing and
paper converting machinery — Part 4: Bookbinding, paper converting and paper finishing machines.

INTERNATIONAL STANDARD ISO 12649:2004(E)

Graphic technology — Safety requirements for binding and
finishing systems and equipment
1 Scope
This International Standard provides safety specifications for the design and construction of binding and
finishing equipment operated in a system configuration or in stand-alone mode.
This International Standard provides safety requirements for the design and construction of equipment used to
convert printed or blank substrates into cut, folded, collated, assembled, bound, or otherwise finished product.
It may also be applied to processes for preparing substrate for the printing process.
It addresses recognized hazards specific to binding and finishing equipment and systems in the following
areas:
 mechanical;
 electrical;
 slipping, tripping, falling;
 ergonomics;
 noise;
 radiation;
 fire and explosion;
 thermal;
 emissions.
This International Standard applies to new machines manufactured after December 31 of the year following
the year of issue of this International Standard.
Equipment covered by this International Standard may be used in a stand-alone configuration, or in
combination with other machines affected by an integrated control system. These may include but are not
limited to, the combinations of the machines noted in Clause 4.

status of a machine in which motion can be initiated by the operator
3.78
remote control
connection to the control station of a machine by use of an external communication link
3.79
routine and regular access
repetitive access to a hazard point that is required for manual feeding of a machine during normal production
activity
3.80
safe condition
machine status in which movement of the main drive motor(s) (prime mover) of the motion zone is prevented,
which may apply to the entire machine or to one or more motion zones, and which exists only when one or
more stop/safe or emergency stop pushbuttons is/are latched in the depressed position
3.81
sheet-folding machine
apparatus to cut, perforate and/or crease single or multiple folds in single sheets of paper
3.82
significant hazard
potential source of severe or disabling injury or death
3.83
single-cycle device
mechanism that ensures that only one cutting cycle occurs for each manual activation or automatic cut
NOTE See anti-repeat device (3.2).
3.84
smooth roller
cylinder
elongated solid body with a circular cross-section having a smooth surface; i.e. with grooves or elevations no
more than 4 mm deep and with circumferential slots no more than 8 mm wide with no sharp or cutting edges
(see Figure 2)
Dimensions in millimetres

3.85
status lights
lights that indicate machine status or machine process condition
NOTE These are not the same as personnel warning lights (3.71).
3.86
stored energy
potential energy that may be released without actuation of the machine drive or controls
3.87
tool
implement, such as a key or wrench, designed to operate a fastener
NOTE An improvised implement such as a coin or fingernail file is not considered to be a tool.
3.88
trip nip bar
movable protective bar located at an in-running nip which, when pushed, activates the interlocked safety
system of the machine
3.89
two-hand control
safety device that consists of two manual control devices that must be operated simultaneously by a single
operator to initiate potentially hazardous machine motion

3.90
warning period
time interval during which machine motion is prevented and a warning is given to personnel that machine
motion is about to occur
3.91
wireless control
transmission of commands and signals between a machine-control system and the motion-control station(s)
using means other than a physical connection
3.92
zero speed
condition of machine movement in which the drive control system is actively holding the machine at a position
and while machine movement is not discernible, machine movement can be initiated without warning
NOTE Zero speed can be considered to be an armed condition (3.3).
