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 12643-1 was prepared by Technical Committee ISO/TC 130, Graphic technology.
This third edition of ISO 12643-1 cancels and replaces the second edition (ISO 12643-1:2009). Significant
changes incorporated into this third edition include, but are not limited to the following:
clarification of requirements for "remote control" versus "remote access";
addition of Clause 6, Verification of safety requirements and/or protective measures;
addition of Annex B listing significant hazards and hazard zones; and
reorganization of clauses to align with requirements in ISO Guide 78, Safety of machinery – Rules for
drafting and presentation of safety standards.
It is the intent of ISO/TC 130 that there be a transition period between the second and third editions of
ISO 12643-1. The user of this part of ISO 12643-1 is referred to Clause 4 of this standard for guidance in this
area.
As from 2014-01-01, ISO 12643-1:2011 will cancel and replace ISO 12643-1:2009. Accordingly, as from
2014-01-01, only ISO 12643-1:2011 will be applicable to new equipment manufactured.
ISO 12643 consists of the following parts, under the general title Graphic technology — Safety requirements
for graphic technology equipment and systems:
Part 1: General requirements
Part 2: Prepress and press equipment and systems
Part 3: Binding and finishing equipment and systems
Part 4: Converting equipment and systems
Part 5: Stand-alone platen presses
Requirements specific to printing prepress and press equipment and systems, binding and finishing
equipment and systems, converting equipment and systems and stand-alone platen presses that are not
included in this part of ISO 12643, are given in subsequent parts of ISO 12643 that contain additional
requirements specific to that type of equipment.

Introduction
This part of ISO 12643 is a type-C standard as stated in ISO 12100.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are covered
are indicated in the Scope of this document.
When requirements of this type-C standard are different from those which are stated in type-A or B standards, the
requirements of this type-C standard take precedence over the requirements of the other standards for machines
that have been designed and built according to the requirements of this type-C standard.
During the development of this part of ISO 12643, existing relevant standards of other countries were taken
into consideration. An effort has been made to take into consideration the requirements of many 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 part of ISO 12643, that has been noted.
This part of ISO 12643 was developed to harmonize the requirements of the following U.S. and European
safety standards:

4 Conformity with this part of ISO 12643
In order to claim conformity with this part of ISO 12643, all equipment manufactured as of 2014-01-01 shall be
in accordance with this third edition of ISO 12643-1 rather than ISO 12643-1:2009.
NOTE Although this third version of ISO 12643-1 cancels and replaces the second edition (ISO 12643-1:2009), a
transition period might be necessary for equipment manufactured prior to 2014-01-01. To meet this need, it is noted that
both versions of ISO 12643-1 can be purchased from ISO and its National Bodies.
5 Safety requirements and/or protective measures
5.1 General
Machinery shall comply with the safety requirements and/or protective measures of this subclause. In addition,
machinery shall be designed according to the principles of ISO 12100 for relevant but not significant hazards
that are not dealt with by this part of ISO 12643 (e.g. sharp edges of the machine frame).
5.2 Risk assessment
Risk assessment on machinery covered by all parts of ISO 12643 shall be conducted in accordance with
ISO 12100.
5.3 Guarding of significant hazards
5.3.1 General
Guarding, consistent with operation of the machine, shall be provided in those areas where it is recognized
that operators are exposed to significant hazards. Exposure to significant hazards is not considered to exist if,
during normal operation, the distance to the hazard complies with those specified in ISO 13857. Machinery
shall be designed using the risk assessment process and principles of ISO 12100 for hazards, and the
relevant parts of ISO 12643 for significant hazards.
Significant hazards vary from machine to machine. It is important that each machine be evaluated to
determine what hazards might exist and that shall be guarded.
Machines should be designed to allow normal production operations such as make-ready, wash-up,
operator-performed maintenance or troubleshooting without machine motion. Where machine motion is
required to perform these functions, guards and safety devices shall provide protection against hazards.
These operations shall be carried out using a hold-to-run device as specified in this part of ISO 12643, and
specified in the requirements for hold-to-run controls defined in ISO 12643-2 for prepress and press
equipment and systems, ISO 12643-3 for binding and finishing equipment and systems, ISO 12643-4 for
converting equipment and systems, or ISO 12643-5 for stand-alone platen presses.
Where moving components or product flow require surveillance, equipment shall be designed to allow the
needed visibility and to allow adjustments, if needed, to equipment operation with the guards remaining closed.
EXAMPLES A transparent guard or remote viewing system.
5.3.2 Guards
5.3.2.1 Guard types and travel
5.3.2.1.1 Types of guards
For the purpose of this part of ISO 12643, there are two types of guards, fixed and movable.
ISO/DIS 12643-1
Guards that do not have to be opened frequently shall be interlocked or shall be fixed in such a way that their
removal necessitates the use of a tool (see 3.62), such as a key or wrench, designed to operate a fastener.
The fixing systems of fixed guards that are designed for access by operators during operations (e.g. set-up,
make-ready, routine cleaning, etc.) shall remain attached to the guards or to the machine when the guards are
removed. Where possible, guards should be incapable of remaining in place without their fixings.
This requirement is not applicable to guards and enclosures removed by trained service personnel performing
maintenance when the machine is not available for production.
All movable guards shall be interlocked in accordance with 5.3.5.
Guards that are designed to be opened, removed, and/or moved at least once per working shift (on average)
during normal operation, with or without the use of a tool, shall be i
